Json deserialize says children could not evaluate- xamarin.forms

I have xamarin.forms app in which I am trying to consume an API. I can get the results but cant deserialize the data. It says "Childern could not be evaluated"
My Json data
{
"success": true,
"user": {
"auth_uuid": "52320",
"current_store": 9,
"permissions": {
"write_notifications": true,
},
"has_accepted_mobile_one_terms": false,
"store": {
"id": 9,
"name": "South Street",
"number": "0009",
}
},
"message": "User Logged In",
"sidebarItems": [
{
"id": 53,
"name": "Notification Center",
}
],
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9"
}
My Corresponding C# class
public clas loginData
{
public class Permissions
{
public bool write_notifications { get; set; }
}
public class Store
{
public int id { get; set; }
public string name { get; set; }
public string number { get; set; }
}
public class User
{
public string auth_uuid { get; set; }
public int current_store { get; set; }
public Permissions permissions { get; set; }
public bool has_accepted_mobile_one_terms { get; set; }
public Store store { get; set; }
}
public class SidebarItem
{
public int id { get; set; }
public string name { get; set; }
}
public class RootObject
{
public bool success { get; set; }
public User user { get; set; }
public string message { get; set; }
public List<SidebarItem> sidebarItems { get; set; }
public string token { get; set; }
}
}
My common class for making API call
public class APICall
{
Uri baseAddress = new Uri(CommonValues.BaseURL);
string apiurl;
string postdata;
public ErrorMessageData errorMessage;
public APICall(string apiurl, string postdata)
{
this.apiurl = apiurl;
this.postdata = postdata;
this.loadingIndicator = loadingIndicator;
errorMessage = null;
}
public T APICallResult<T>()
{
try
{
var client = new HttpClient { BaseAddress = baseAddress };
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var req = new HttpRequestMessage(HttpMethod.Post, apiurl);
req.Content = new StringContent(postdata, Encoding.UTF8, "application/json");
string stringObtained = "";
Task<string> task = Task.Run(async () => await Threading(client, req));
task.Wait();
stringObtained = task.Result;
var jsonObtained = Regex.Unescape(stringObtained);
var resultJSON = '[' + jsonObtained + ']';
T resultObject;//Generic type object
try
{
resultObject = JsonConvert.DeserializeObject<T>(resultJSON);
return resultObject;
}
catch (Exception)
{
List<ErrorMessageData> errorMessages = JsonConvert.DeserializeObject<List<ErrorMessageData>>(resultJSON);
errorMessage = errorMessages[0];
return default(T);
}
}
catch (Exception e)
{
errorMessage = new ErrorMessageData();
errorMessage.Flag = false;
errorMessage.Message = e.Message;
return default(T);
}
}
async Task<string> Threading(HttpClient client, HttpRequestMessage req)
{
var resp = await client.SendAsync(req);
resp.EnsureSuccessStatusCode();
string stringObtained = await resp.Content.ReadAsStringAsync();
return stringObtained;
}
}
How I am making API call
ObservableCollection<loginData> AuthDataObj;
string postdataForAuth = "{\"email\":\"" + "sample#sam.com" + "\",\"password\":\"" + "1234" + "\"}";
NCAPICall callForAuth = new APICall("/auth/login", postdataForAuth, null);
try
{
AuthDataObj = callForAuth.APICallResult<ObservableCollection<loginData>>();
}
catch (Exception ex)
{
await DisplayAlert("Error", ex.Message, "ok");
}
How to solve this issue? Is this something related to mapping of data to my model class?Any help is appriciated.

You need to use RootObject for the deserialization.
Change this line of code
var AuthDataObj = callForAuth.APICallResult<ObservableCollection<RootObject>>();

how to get value from json response in xamarin android?(user login purpose in android app)

c# code:-
var handler = new HttpClientHandler();
HttpClient client = new HttpClient(handler);
string result = await client.GetStringAsync(url);
Console.WriteLine(result);
json respose(result):-
{
"accountstab": [
{
"LoginType": "r",
"RepId": 3368,
"RepName": "Aachi's M",
"RepUName": "aachis",
"RepPwd": "aachis123",
"WhlId": null,
"RepLocalId": null,
"WhoName": "Aachi's M",
"WhoTin": "32661034",
"WhoEmail": "hanee#gmail.com"
},
{
"LoginType": "r",
"RepId": 3335,
"RepName": "AL-NAJA M",
"RepUName": "alnaja",
"RepPwd": "chemmad",
"WhlId": null,
"RepLocalId": null,
"WhoName": "AL-NAJA",
"WhoTin": "7222075",
"WhoEmail": "abbas#gmail.com"
}
]
}
model class:
public class RootObject
{
public List<Accountstab> accountstab { get; set; }
}
public class Accountstab
{
public string LoginType { get; set; }
public int RepId { get; set; }
public string RepName { get; set; }
public string RepUName { get; set; }
public string RepPwd { get; set; }
public int? WhlId { get; set; }
public int? RepLocalId { get; set; }
public string WhoName { get; set; }
public string WhoTin { get; set; }
public string WhoEmail { get; set; }
}

I can be done with Newtonsoft.Json dll from NuGet:
using Newtonsoft.Json;
// ...
RootObject json = JsonConvert.DeserializeObject<RootObject>(result);
Usage example:
foreach (var item in json.accountstab)
Console.WriteLine(item.RepUName);
Output:
aachis
alnaja

if there is any problem with string value="null" in json , public string WhoTin { get; set; } this field are null is some records
The error of you json string is not caused by the null, it caused by the ' in the json below.
"RepName": "Aachi's M",
"WhoName": "Aachi's M",
The way you used to deserliaze the json data in Xamarin.forms is correct.
var jsondata = JsonConvert.DeserializeObject<Rootobject>(json);
When you change the ' in json data, it would be okay.
"RepName": "Aachi s M"
"WhoName": "Aachi s M",

Retrieving an element from JSON response

I am trying to get a field from the response from the rest services in the Web API we are building. The JSON looks like this:
{
"d": {
"results": [{
"__metadata": {
"id": "Web/Lists(guid'4ddc-41e2-bb44-0f92ad2c0b07')/Items(164)",
"uri": "https://teams.ax.org/sites/js/project/_api/Web/Lists(guid'4ddc-41e2-bb44-0f92ad2c0b07')/Items(164)",
"etag": "\"6\"",
"type": "SP.Data.St_x0020_CdsListItem"
},
"Folder": {
"__deferred": {
"uri": "https://teams.ax.org/sites/js/project/_api/Web/Lists(guid'4ddc-41e2-bb44-0f92ad2c0b07')/Items(164)/Folder"
}
},
"ParentList": {
"__deferred": {
"uri": "https://teams.ax.org/sites/js/project/_api/Web/Lists(guid'4ddc-41e2-bb44-0f92ad2c0b07')/Items(164)/ParentList"
}
},
"PM_x0020_NameId": 220,
"St_x0020_Name": "<div class=\"ExternalClassA14DB0FF86994403B827D91158CF34B0\">KO</div>",
}]
}}
I created these model classes:
public class SharepointDTO
{
public class Metadata
{
[JsonProperty("id")]
public string id { get; set; }
[JsonProperty("uri")]
public string uri { get; set; }
[JsonProperty("etag")]
public string etag { get; set; }
[JsonProperty("type")]
public string type { get; set; }
}
public class Deferred
{
[JsonProperty("uri")]
public string uri { get; set; }
}
public class Folder
{
[JsonProperty("__deferred")]
public Deferred __deferred { get; set; }
}
public class ParentList
{
[JsonProperty("__deferred")]
public Deferred __deferred { get; set; }
}
public class Result
{
[JsonProperty("__metadata")]
public Metadata __metadata { get; set; }
[JsonProperty("Folder")]
public Folder Folder { get; set; }
[JsonProperty("ParentList")]
public ParentList ParentList { get; set; }
[JsonProperty("PM_x0020_NameId")]
public int PM_x0020_NameId { get; set; }
[JsonProperty("St_x0020_Name")]
public string St_x0020_Name { get; set; }
}
public class D
{
[JsonProperty("results")]
public IList<Result> results { get; set; }
}
public class RootObject
{
[JsonProperty("d")]
public D d { get; set; }
}
}
No trying to call the rest service from the Web API and need to get the St_x0020_Name from response and store in a string.
SharepointDTO.RootObject retSharepointobj = await GetfromSharepoint(StNumber);
string StName = retSharepointobj.d.results.St_x0020_Name.ToString();
I am deserializing the JSON in the GetfromSharepoint method like
using (var client_sharePoint = new HttpClient(handler))
{
var response = client_sharePoint.GetAsync(SP_URL).Result;
var responsedata = await response.Content.ReadAsStringAsync();
var returnObj = JsonConvert.DeserializeObject<SharepointDTO.RootObject>(responsedata);
return returnObj;
}
But it throws an error:
'System.Collections.Generic.IList' does not contain a definition for 'St_x0020_Name' and no extension method 'St_x0020_Name' accepting a first argument of type 'System.Collections.Generic.IList' could be found (are you missing a using directive or an assembly reference?)

results is an array, so you have either loop thru like
foreach(var item in retSharepointobj.d.results){
string StName = item.St_x0020_Name.ToString();
}
or get a specific element, for example a first element like:
SharepointDTO.RootObject retSharepointobj = await GetfromSharepoint(StNumber);
string StName = retSharepointobj.d.results[0].St_x0020_Name.ToString();
or you can add an extra check like that
SharepointDTO.RootObject retSharepointobj = await GetfromSharepoint(StNumber);
if(retSharepointobj.d.results.length > 0){
string StName = retSharepointobj.d.results[0].St_x0020_Name.ToString();
}

Shouldn't this line:
string StName = retSharepointobj.d.results.St_x0020_Name.ToString();
Be like this?
string StName = retSharepointobj.d.results.First().St_x0020_Name.ToString();

Parse the JSON syntax if it is not parsed well

How do I parse the JSON data if it is not well parsed from newtonsoft json. Please refer my below code:
var web_uri = new Uri("www.example.com");
var resp = await client2.GetAsync(web_uri);
var resp_to_str = await resp.Content.ReadAsStringAsync();
var json_obj = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(resp_to_str);
Finally i parsed the JSON. now, it produces as expected.
{
"Sex": "Male",
"category": "A",
"ID": 14,
"created": "2016-03-03",
"Tag": "2340",
"members": [{
"type": "A",
"name": "fam_mem",
"state": "ca",
"Family": {
"myGuardName": "tony",
"details": [{
"address": "ca",
"type": "A"
}]
}
}]
}
**RootObject omyclass = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json_obj);**
Now i am getting error at the above line:
An exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in System.Linq.Expressions.dll but was not handled in user code
Additional information: The best overloaded method match for 'Newtonsoft.Json.JsonConvert.DeserializeObject(string)' has some invalid arguments
public class Detail
{
public string address { get; set; }
public string type { get; set; }
}
public class Family
{
public string myGuardName { get; set; }
public List<Detail> details { get; set; }
}
public class Member
{
public string type { get; set; }
public string name { get; set; }
public string state { get; set; }
public Family Family { get; set; }
}
public class RootObject
{
public string Sex { get; set; }
public string category { get; set; }
public int ID { get; set; }
public string created { get; set; }
public string Tag { get; set; }
public List<Member> members { get; set; }
}
TextBlock.Text = omyclass
I have updated the question

Hope it helps:
var web_uri = new Uri("www.example.com");
var resp = await client2.GetAsync(web_uri);
var resp_to_str = await resp.Content.ReadAsStringAsync();
RootObject omyclass = JsonConvert.DeserializeObject<RootObject>(resp_to_str); //pass the response string here.
Updated from OP's comment:
textBlock2.Text = omyclass + "----!"; will not work because omyclass is RootObject, not a string
You have to get the info you need and append it to textBlock2:
textBlock2.text = omyclass.Sex + "----!";
UPDATE 2 (OP get string as key value pair):
Usage: textBlock2.text = omyclass + "----!";
Override RootObject.ToString() and use Reflection to get properties & property values
public class RootObject
{
public string Sex { get; set; }
public string category { get; set; }
public int ID { get; set; }
public string created { get; set; }
public string Tag { get; set; }
public List<Member> members { get; set; }
public override string ToString()
{
var values = new List<string>();
foreach (var property in GetType().GetProperties())
{
values.Add(property.Name + ": " + property.GetValue(this));
}
return string.Join(", ", values);
}
}

The problem is that JsonConvert.DeserializeObject<T>(string) expects a string as an input argument -- but you are not passing in a string. You are passing in json_obj which is a dynamic returned by a previous call to deserialize:
var json_obj = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(resp_to_str);
var omyclass = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json_obj);
What JsonConvert returns from the first dynamic call is in fact a JToken containing a tree of LINQ-to-JSON tokens -- not a string. This causes the RuntimeBinderException upon making the second call.
There is no need to double-deserialize the JSON string in this manner. Just pass the resp_to_str to JsonConvert.DeserializeObject<RootObject>():
var omyclass = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(resp_to_str);
Prototype fiddle.
Update
If you want to see all the fields and properties of the deserialized class in a text box, you could re-serialize it to JSON:
var reserializedJson = JsonConvert.SerializeObject(omyclass, Formatting.Indented);
textBlock2.Text = reserializedJson;
If you do
textBlock2.Text = omyclass + "----!"
You are just showing the ToString() value for your class. And since you have not overridden this method it will just show the class name.
If you don't want to re-serialize you could use the following extension method:
public static class ObjectExtensions
{
public static StringBuilder ToStringWithReflection<T>(this T obj, StringBuilder sb)
{
sb = sb ?? new StringBuilder();
if (obj == null)
return sb;
if (obj is IEnumerable)
{
sb.Append("[");
var first = true;
foreach (var item in ((IEnumerable)obj))
{
if (!first)
sb.Append(",");
sb.Append(item == null ? "" : item.ToString());
first = false;
}
sb.Append("]");
}
else
{
var type = obj.GetType();
var fields = type.GetFields();
var properties = type.GetProperties().Where(p => p.GetIndexParameters().Length == 0 && p.GetGetMethod(true) != null && p.CanRead);
var query = fields
.Select(f => new KeyValuePair<string, object>(f.Name, f.GetValue(obj)))
.Concat(properties
.Select(p => new KeyValuePair<string, object>(p.Name, p.GetValue(obj, null))));
sb.Append("{").Append(obj.GetType().Name).Append(": ");
var first = true;
foreach (var pair in query)
{
if (!first)
sb.Append(", ");
sb.Append(pair.Key).Append(": ");
if (pair.Value is IEnumerable && !(pair.Value is string))
pair.Value.ToStringWithReflection(sb);
else
sb.Append(pair.Value == null ? "null" : pair.Value.ToString());
first = false;
}
sb.Append("}");
}
return sb;
}
public static string ToStringWithReflection<T>(this T obj)
{
return obj.ToStringWithReflection(new StringBuilder()).ToString();
}
}
Then do
textBlock2.Text = omyclass.ToStringWithReflection() + "----!"
Update 2
Or, if you want to include properties from your object hierarchy recursively, you can override the ToString() method of each, like so:
public class Detail
{
public string address { get; set; }
public string type { get; set; }
public override string ToString() { return this.ToStringWithReflection(); }
}
public class Family
{
public string myGuardName { get; set; }
public List<Detail> details { get; set; }
public override string ToString() { return this.ToStringWithReflection(); }
}
public class Member
{
public string type { get; set; }
public string name { get; set; }
public string state { get; set; }
public Family Family { get; set; }
public override string ToString() { return this.ToStringWithReflection(); }
}
public class RootObject
{
public string Sex { get; set; }
public string category { get; set; }
public int ID { get; set; }
public string created { get; set; }
public string Tag { get; set; }
public List<Member> members { get; set; }
public override string ToString() { return this.ToStringWithReflection(); }
}
Then the ToString() output will be:
{RootObject: Sex: Male, category: A, ID: 14, created: 2016-03-03, Tag: 2340, members: [{Member: type: A, name: fam_mem, state: ca, Family: {Family: myGuardName: tony, details: [{Detail: address: ca, type: A}]}}]}

You Can Use a Custom Json formatter and parse it the way you want.It can be implemented at framework level so that all data is parsed according to your requirements.Inherit the custom formatter from MediaTypeFormatter.
Implement the virtual and abstract functions of MediaTypeFormatter.Pasre the data according to your requirements here.
I have implemented the formatter this way and it even parses complex data to match the data that i want.

When serializing complex Json if not deserialized correctly the value becomes null.For deserializing complex Json use JsonMediaTypeFormatter.
My Example
In your config File add
config.Formatters.Clear();
config.Formatters.Insert(0, new JsonNetFormatterDecide()); // My custom formatter
config.Formatters.Insert(1, new JsonMediaTypeFormatter());//Default Formatter
config.MapHttpAttributeRoutes();`
So i used my custom formatter for all get operations.Format the data as i want and sent to client.The problem i faced was while accepting complex Json data(such as Jsonarrays within Jsonobjects). So in my config file i added the JsonMediaTypeFormatter() in index 1 of Config.formatters.
In my custom formatter
public override bool CanReadType(Type type)
{
return false;
}
This makes JsonMediaTypeFormatter which is a very popular formatter to Deserialize complex data to do the deserialization.
The bottomline is that you can use JsonMediaTypeFormatter toDeserialize complex Json Data
It has some predefined functions to deserialize.
By looking at your Json it seems as if Json arrays within Json objects is the reason why your Json is not deserialing correctly
If you plan to write your custom Json formatter ,You can implement at framework level like
public class JsonNetFormatterDecide : MediaTypeFormatter
{
//......
public override bool CanReadType(Type type)
{
return false; //this causes the // project to use the second formatter in the config file ie,JsonMediaTypeFormatter or the //default Json Formatter
}
}

Json deserialize not working in C# window 2012 servers

I am trying to deserialize the json string from Rest webserive in C#. Following is jsonstring and classes I used. But after deserialize it is giving null/empty value on server.But in local its working as expected. So what's going wrong with me?

In my local with local URL, im able to deserialize the json string and assigned to partnerdata. In server (windows 2012) after deployed into IIS(8.5) parameters values are null/ empty and there was no error while deserialize . Rest WS sending expected response's. and restResponse.error this value deserialized correctly but parameters are not deserialized.
So what's going wrong with me?

In the JSON string you show, "parameters" is an array of name/value pairs:
{
"error": false,
"parameters": [
{
"Programs": "ZZ_UNUSED_EU-01pp-Q669;EU-PPP-O003;ZZ_UNUSED_EU-PPP-CO05;100000;pbse;EU-m110-2007;EU-zz33-L053;EU-zz21-z084;ZZ_UNUSED_EU-01pp-Q875;EU-zz05-L029;ZZ_UNUSED_EU-RAD-003;ZZ_UNUSED_EU-RAD-004;ZZ_UNUSED_EU-RAD-007;ZZ_UNUSED_EU-RAD-012;ZZ_UNUSED_EU-RAD-015;ZZ_UNUSED_EU-zz22-RF21;ZZ_UNUSED_EU-PPP-CO130;ZZ_UNUSED_EU-01pp-Q962;ZZ_UNUSED_EU-01pp-Q963;EU-LandR-COM;EU-01pp-O960;EU-SI-HP-INTL;G_PC_SQ;G_Survey_Inv_TPE-FY11;G_MADO_3Com;G_eLocator_AIS;G_eLocator_ATP;G_eLocator_SCE;G_eLocator_TECI;G_L&R_SCREENED;G_L&R_CASE_OPEN;EU-MDF-Tool;EU-DI-SPT-FLASHPRO;EU-DI-SPT-FLASHPRO-FY11;EU-DI-SPT-FLASHPRO-FY12;G_SPT_PCLM_Prospect;G_SPT_PCLM_Enrolled;SPEC_P1_S1_GOLD_PPS_CAN;G_SPT_Joint_Business_Planning;EU_RET_CE_SCOPE;G_PARTNER_HPQ;ZZ_UNUSED_EU-01pp-O972;SPEC_P1_SERV_SILV_CAN;SPEC_P1_STOR_SILV_CAN;SPEC_P1_NW_SILV_CAN;SPEC_P1_S1_SILV_CAN;PM_P1_PLAT_PART_CAN;PM_P1_SILV_PART_PPS_SM_CAN;SPEC_P1_WK_GOLD_CAN;ZZ_UNUSED_EU-01pp-Q018;"
},
{
"PartnerSubTypes": "G_Tgt_Commercial_T2_Reseller_S;SSP;Supplies Commercial;"
},
Your code is attempting to deserialize parameters as a single object with many properties, e.g.:
{
"error": false,
"parameters": {
"Programs": "ZZ_UNUSED_EU-01pp-Q669;EU-PPP-O003;ZZ_UNUSED_EU-PPP-CO05;100000;pbse;EU-m110-2007;EU-zz33-L053;EU-zz21-z084;ZZ_UNUSED_EU-01pp-Q875;EU-zz05-L029;ZZ_UNUSED_EU-RAD-003;ZZ_UNUSED_EU-RAD-004;ZZ_UNUSED_EU-RAD-007;ZZ_UNUSED_EU-RAD-012;ZZ_UNUSED_EU-RAD-015;ZZ_UNUSED_EU-zz22-RF21;ZZ_UNUSED_EU-PPP-CO130;ZZ_UNUSED_EU-01pp-Q962;ZZ_UNUSED_EU-01pp-Q963;EU-LandR-COM;EU-01pp-O960;EU-SI-HP-INTL;G_PC_SQ;G_Survey_Inv_TPE-FY11;G_MADO_3Com;G_eLocator_AIS;G_eLocator_ATP;G_eLocator_SCE;G_eLocator_TECI;G_L&R_SCREENED;G_L&R_CASE_OPEN;EU-MDF-Tool;EU-DI-SPT-FLASHPRO;EU-DI-SPT-FLASHPRO-FY11;EU-DI-SPT-FLASHPRO-FY12;G_SPT_PCLM_Prospect;G_SPT_PCLM_Enrolled;SPEC_P1_S1_GOLD_PPS_CAN;G_SPT_Joint_Business_Planning;EU_RET_CE_SCOPE;G_PARTNER_HPQ;ZZ_UNUSED_EU-01pp-O972;SPEC_P1_SERV_SILV_CAN;SPEC_P1_STOR_SILV_CAN;SPEC_P1_NW_SILV_CAN;SPEC_P1_S1_SILV_CAN;PM_P1_PLAT_PART_CAN;PM_P1_SILV_PART_PPS_SM_CAN;SPEC_P1_WK_GOLD_CAN;ZZ_UNUSED_EU-01pp-Q018;"
"PartnerSubTypes": ""G_Tgt_Commercial_T2_Reseller_S;SSP;Supplies Commercial;""
In other words, the JSON you are receiving for "parameters"corresponds to a List<Dictionary<string, string>> with UseSimpleDictionaryFormat = false, rather than a single POCO with various properties.
Update
Given that this is a legacy application using an older version of .Net (possibly with some configuration issues, as the var keyword is causing you to have a compiler error), I am going to suggest switching to JavaScriptSerializer which is also a built-in .Net component. Change your data model as follows:
public class PartnerDataDictionary
{
public PartnerDataDictionary()
{
this.ParameterDictionary = new Dictionary<string, string>();
}
string _error;
public string error { get { return _error; } set { _error = value; } }
string _message;
public string message { get { return _message; } set { _message = value; } }
[System.Web.Script.Serialization.ScriptIgnore]
public Dictionary<string, string> ParameterDictionary { get; set; }
public List<Dictionary<string, string>> parameters
{
get
{
List<Dictionary<string, string>> dictList = new List<Dictionary<string, string>>();
foreach (KeyValuePair<string, string> pair in ParameterDictionary)
{
Dictionary<string, string> subDict = new Dictionary<string,string>(1);
subDict[pair.Key] = pair.Value;
dictList.Add(subDict);
}
return dictList;
}
set
{
if (value == null)
{
ParameterDictionary = new Dictionary<string, string>();
return;
}
Dictionary<string, string> dict = new Dictionary<string, string>();
foreach (Dictionary<string, string> entry in value)
foreach (KeyValuePair<string, string> pair in entry)
dict.Add(pair.Key, pair.Value);
ParameterDictionary = dict;
}
}
public string GetParameter(string key)
{
string value;
if (ParameterDictionary.TryGetValue(key, out value))
return value;
return null;
}
public void SetParameter(string key, string value)
{
ParameterDictionary[key] = value;
}
// Add other properties as needed, marking them as `ScriptIgnore`:
[System.Web.Script.Serialization.ScriptIgnore]
public string Programs
{
get { return GetParameter("Programs"); }
set { SetParameter("Programs", value); }
}
}
What I am doing here is reading the JSON as a list of dictionaries, then combining them into a dictionary in the setter for ease of use.
Then you can read and write your JSON parameters as follows:
PartnerDataDictionary data = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<PartnerDataDictionary>(json);
string programs = data.Programs;
Debug.WriteLine(programs);
Original Answer
You could simply change your PartnerData class to have such a list of dictionaries. If you want to continue to use your current data model, and also use DataContractJsonSerializer, you are going to need to introduce a data contract surrogate to do the conversion:
public class ObjectToPropertyDictionaryArraySurrogate<T> : IDataContractSurrogate
{
class ListDictionaryArray : List<Dictionary<string, string>>
{
}
#region IDataContractSurrogate Members
public object GetCustomDataToExport(Type clrType, Type dataContractType)
{
throw new NotImplementedException();
}
public object GetCustomDataToExport(MemberInfo memberInfo, Type dataContractType)
{
throw new NotImplementedException();
}
public Type GetDataContractType(Type type)
{
if (type == typeof(T))
return typeof(ListDictionaryArray);
return type;
}
public object GetDeserializedObject(object obj, Type targetType)
{
if (obj is ListDictionaryArray)
{
var array = (ListDictionaryArray)obj;
var dict = array.SelectMany(pair => pair).ToDictionary(pair => pair.Key, pair => pair.Value);
var json = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(dict);
return DataContractJsonSerializerHelper.GetObject<T>(json, new DataContractJsonSerializerSettings { UseSimpleDictionaryFormat = true });
}
return obj;
}
public void GetKnownCustomDataTypes(Collection<Type> customDataTypes)
{
throw new NotImplementedException();
}
public object GetObjectToSerialize(object obj, Type targetType)
{
if (obj.GetType() == typeof(T))
{
var json = DataContractJsonSerializerHelper.GetJson((T)obj, new DataContractJsonSerializerSettings { UseSimpleDictionaryFormat = true });
var dict = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<Dictionary<string, string>>(json);
var array = new ListDictionaryArray();
array.AddRange(dict.Select(pair => new[] { pair }.ToDictionary(p => p.Key, p => p.Value)));
return array;
}
return obj;
}
public Type GetReferencedTypeOnImport(string typeName, string typeNamespace, object customData)
{
throw new NotImplementedException();
}
public System.CodeDom.CodeTypeDeclaration ProcessImportedType(System.CodeDom.CodeTypeDeclaration typeDeclaration, System.CodeDom.CodeCompileUnit compileUnit)
{
throw new NotImplementedException();
}
#endregion
}
public static class DataContractJsonSerializerHelper
{
public static string GetJson<T>(T obj, DataContractJsonSerializer serializer)
{
using (var memory = new MemoryStream())
{
serializer.WriteObject(memory, obj);
memory.Seek(0, SeekOrigin.Begin);
using (var reader = new StreamReader(memory))
{
return reader.ReadToEnd();
}
}
}
public static string GetJson<T>(T obj)
{
var serializer = new DataContractJsonSerializer(typeof(T));
return GetJson(obj, serializer);
}
public static string GetJson<T>(T obj, DataContractJsonSerializerSettings settings)
{
var serializer = new DataContractJsonSerializer(obj.GetType(), settings);
return GetJson<T>(obj, serializer);
}
public static T GetObject<T>(string json, DataContractJsonSerializer serializer)
{
using (var stream = GenerateStreamFromString(json))
{
var obj = serializer.ReadObject(stream);
return (T)obj;
}
}
public static T GetObject<T>(string json)
{
var serializer = new DataContractJsonSerializer(typeof(T));
return GetObject<T>(json, serializer);
}
public static T GetObject<T>(string json, DataContractJsonSerializerSettings settings)
{
var serializer = new DataContractJsonSerializer(typeof(T), settings);
return GetObject<T>(json, serializer);
}
private static MemoryStream GenerateStreamFromString(string value)
{
return new MemoryStream(Encoding.Unicode.GetBytes(value ?? ""));
}
}
And then use it like:
var settings = new DataContractJsonSerializerSettings
{
UseSimpleDictionaryFormat = true,
DataContractSurrogate = new ObjectToPropertyDictionaryArraySurrogate<Paramter>(),
};
DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(PartnerData), settings);
