Deseriaize Json from WebAPI using HttpClient - c#

I have the following Json format returned from a WebAPI. Can you guys help to deserialize please?.
{
"#odata.context":"http://....... ","value":[
**{
"RecordNumber":"LDxxxx","RecordType":"Loan","PropertyAddress":{ "Address1":"601 xxxx","Address2":null,"Zip":"99999","City":"abc","State":"ab","County":"abcd" }
,"Summary":{ "BorrowerName":null,"ProductCode":null,"Status":"Not Registered" }
}**,{
"RecordNumber":"LDxxxx","RecordType":"Loan","PropertyAddress":{ "Address1":"601 xxxx","Address2":null,"Zip":"99999","City":"abc","State":"ab","County":"abcd" }
,"Summary":{ "BorrowerName":null,"ProductCode":null,"Status":"Not Registered" }
},
….]
}
I need what's in the value element. The bold is what is repeated in the return from API. I created a class that matches the description as below.
public class RootObject
{
[JsonProperty(PropertyName = "RecordNumber")]
public string RecordNumber { get; set; }
[JsonProperty(PropertyName = "RecordType")]
public string RecordType { get; set; }
[JsonProperty(PropertyName = "PropertyAddress")]
public PropertyAddress PropertyAddress { get; set; }
[JsonProperty(PropertyName = "Summary")]
public Summary Summary { get; set; }
}
Was able to skip the first record in the Json array using the following, got the "Value" part....but have not been successful in retrieving the "Value" object
var dict = JsonConvert.DeserializeObject<Dictionary<string, object>>(forecast);
foreach (var kv in dict.Skip(1))
{
JArray jsonVal = JArray.Parse(kv.Value.ToString());
}
Appreciate your help.

You can deserialize to concrete classes (with the help of http://json2csharp.com/)
var result = JsonConvert.DeserializeObject<SOTest.Result>(json);
public class SOTest
{
public class PropertyAddress
{
public string Address1 { get; set; }
public object Address2 { get; set; }
public string Zip { get; set; }
public string City { get; set; }
public string State { get; set; }
public string County { get; set; }
}
public class Summary
{
public object BorrowerName { get; set; }
public object ProductCode { get; set; }
public string Status { get; set; }
}
public class Value
{
public string RecordNumber { get; set; }
public string RecordType { get; set; }
public PropertyAddress PropertyAddress { get; set; }
public Summary Summary { get; set; }
}
public class Result
{
[JsonProperty("#odata.context")]
public string Context { get; set; }
public List<Value> Value { get; set; }
}
}

Error -
Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[Property]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'property_id', line 1, position 15.'
It is not deserializing because it is not valid json. To make it valid, and to make it a List<Property> add [ to the beginning of the json and ] to the end of the json. Just enclose the json in [ ... ] to make it valid and it will deserialize assuming the rest of it is valid and is not missing any commas or brackets.
try this, you will have to install NewtonsoftJson. It was tested using Visual Studio and Postman and works properly.
var jsonOrig= ...your json
var json = JsonConvert.SerializeObject(jsonOrig);
var jsonObj = JsonConvert.DeserializeObject<DataRoot>(json);

Problem trying to deserialize a json with a model

I am trying to deserialize a json (using Newtonsoft.Json), i created the classes, but in json code there is a variable that i don't know if it is corrected or i don't know how to deserialize.
I am getting a null exception on line : MessageBox.Show(root.matriculations._14000.name)
private void btnImportaDados_Click(object sender, EventArgs e)
{
string getDataUrl = "https://xxx.xxx.com/api/matriculations/get.json?entity_code=14000";
try
{
using (var webClient = new System.Net.WebClient())
{
var json = webClient.DownloadString(getDataUrl);
var root = JsonConvert.DeserializeObject<Rootobject>(json);
MessageBox.Show(root.matriculations._14000.name);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
public class Rootobject
{
public Matriculations matriculations { get; set; }
}
public class Matriculations
{
public _14000 _14000 { get; set; }
}
public class _14000

But that "14000" is a varible value depending from the parameter passed.
How can i do it?
Thank You.
Since 14000 cannot be a variable name you will have to resort to some manual intervention to capture that dynamic value. The cleanest way is to remove the Matriculations class and replace it with Dictionary<int, _14000> (or Dictionary<string, _14000>).
public class Rootobject
{
public Dictionary<int, _14000> matriculations { get; set; }
}
This will ensure that the key is captured correctly even if it is a number. You can read the object from the dictionary's values as such: root.matriculations.Values.First().name. (Remember to import System.Linq for using .First().)
For clarity you can rename _14000 to something more descriptive.
You do not have _14000 in returned JSON but 14000 under matriculations.

How to read sections of JSON document?

I have a JSON document and I want to access the details of the STATUS SECTION but it keeps returning null.
JSON Data is as shown:
{
"results":[
{
"messageId":"15712480583306574",
"to":"",
"from":"TestServer",
"sentAt":"2019-10-16T17:47:38.368+0000",
"doneAt":"2019-10-16T17:47:38.370+0000",
"smsCount":1,
"mccMnc":"null",
"price":{
"pricePerMessage":0.0,
"currency":"USD"
},
"status":{
"groupId":5,
"groupName":"REJECTED",
"id":8,
"name":"REJECTED_PREFIX_MISSING",
"description":"Number prefix missing"
},
"error":{
"groupId":0,
"groupName":"OK",
"id":0,
"name":"NO_ERROR",
"description":"No Error",
"permanent":false
}
}
]
}
C# Code is:
string JsonData = response.Content.ToString();
dynamic results = JsonConvert.DeserializeObject<dynamic>(JsonData);
var statuses = results.status;
foreach(var stat in statuses) {
string groupname = stat.groupName.Value;
string name = stat.name.Value;
string description = stat.description.Value;
}
It keeps returning null, How can I access these members? I am using Newtonsoft.
If you want to access the status object property you need to rewrite your whole code.
string JsonData = response.Content.ToString();
var input = JObject.Parse(str);
var results = input["results"].Children();
var status = results.First()["status"];
string groupname = status["groupName"].ToString();
string name = status["name"].ToString();
string description = status["description"].ToString();
Console.WriteLine(groupname);
Console.WriteLine(name);
Console.WriteLine(description);
The result in Console
REJECTED
REJECTED_PREFIX_MISSING
Number prefix missing
But I would rather use concrete class. You need to create multiple classes. Here is good example.
public class Envelope
{
public List<Item> Results { get; set; }
}
public class Item
{
public Status Status { get; set; }
}
public class Status
{
public int GroupId { get; set; }
public string GroupName { get; set; }
public int Id { get; set; }
public string Name { get; set; }
public string Description { get; set; }
}
After that the usage is much simpler.
string JsonData = response.Content.ToString();
MyEnvelope envelope = JsonConvert.DeserializeObject<MyEnvelope>(JsonData);
var status = envelope.results[0].status;
Console.WriteLine(status.GroupName);
Console.WriteLine(status.Name);
Console.WriteLine(status.Description);
Finest Option: Create A model for the JSON.
public class Price
{
public double pricePerMessage { get; set; }
public string currency { get; set; }
}
public class Status
{
public int groupId { get; set; }
public string groupName { get; set; }
public int id { get; set; }
public string name { get; set; }
public string description { get; set; }
}
public class Error
{
public int groupId { get; set; }
public string groupName { get; set; }
public int id { get; set; }
public string name { get; set; }
public string description { get; set; }
public bool permanent { get; set; }
}
public class Result
{
public string messageId { get; set; }
public string to { get; set; }
public string from { get; set; }
public DateTime sentAt { get; set; }
public DateTime doneAt { get; set; }
public int smsCount { get; set; }
public string mccMnc { get; set; }
public Price price { get; set; }
public Status status { get; set; }
public Error error { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
Then do RootObject results = JsonConvert.DeserializeObject<RootObject>(JsonData);
Fair Option: Get the exact JToken you want.
using System;
using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;
using Newtonsoft.Json.Linq;
public class Program
{
public static void Main()
{
string jsonData = "{\"results\":[{\"messageId\":\"15712480583306574\",\"to\":\"\",\"from\":\"TestServer\",\"sentAt\":\"2019-10-16T17:47:38.368+0000\",\"doneAt\":\"2019-10-16T17:47:38.370+0000\",\"smsCount\":1,\"mccMnc\":\"null\",\"price\":{\"pricePerMessage\":0.0,\"currency\":\"USD\"},\"status\":{\"groupId\":5,\"groupName\":\"REJECTED\",\"id\":8,\"name\":\"REJECTED_PREFIX_MISSING\",\"description\":\"Number prefix missing\"},\"error\":{\"groupId\":0,\"groupName\":\"OK\",\"id\":0,\"name\":\"NO_ERROR\",\"description\":\"No Error\",\"permanent\":false}}]}";
JObject jObject = JObject.Parse(jsonData);
Console.WriteLine(jObject.SelectToken("results[0].status"));
}
}

Deserialize Json List to C# List objects

I have class which return json string but I want to deserilize it into C# List Objects. My current code look like this
public class JsonBuilder
{
public static string BuildJson(DateTime fromDate, DateTime toDate)
{
var list = new List<dynamic>();
// create list with json object from service
var jsonObjList = JsonConvert.SerializeObject(list);
var des = (List<JsonObject>)JsonConvert.DeserializeObject(jsonObjList, typeof(List<JsonObject>));
return JsonConvert.SerializeObject(list);
}
Exception thrown when it tries to deserialize the "serialized" json string
An exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll but was not handled in user code
Additional information: Error converting value
InnerException:
{"Could not cast or convert from System.String to MvcWebApp.Models.JsonObject."}
Have you tried this:
var des = (List<DeserializeObjects>)JsonConvert.DeserializeObject(jsonObjList, jsonObjList.GetType()));
or this:
var des = (List<DeserializeObjects>)JsonConvert.DeserializeObject(jsonObjList, typeof(List<dynamic>));
else this post could also help you to achieve your goal:
Deserialize json object into dynamic object using Json.net
try this
var jsonObjList = JsonConvert.SerializeObject(list);
dynamic resultList = JsonConvert.DeserializeObject(jsonObjList);
I would try with this class
public class Author
{
public int id { get; set; }
public string slug { get; set; }
public string name { get; set; }
public string first_name { get; set; }
public string last_name { get; set; }
public string nickname { get; set; }
public string url { get; set; }
public string description { get; set; }
}
public class CustomFields
{
public List<string> tags { get; set; }
}
public class Post
{
public int id { get; set; }
public string type { get; set; }
public string slug { get; set; }
public string url { get; set; }
public string status { get; set; }
public string title { get; set; }
public string title_plain { get; set; }
public string content { get; set; }
public string excerpt { get; set; }
public string date { get; set; }
public string modified { get; set; }
public List<object> categories { get; set; }
public List<object> tags { get; set; }
public Author author { get; set; }
public List<object> comments { get; set; }
public List<object> attachments { get; set; }
public int comment_count { get; set; }
public string comment_status { get; set; }
public CustomFields custom_fields { get; set; }
}
public class YourObject
{
public string status { get; set; }
public int count { get; set; }
public int count_total { get; set; }
public int pages { get; set; }
public List<Post> posts { get; set; }
}
Then, you deserialize with this :
var yourObject = JsonConvert.DeserializeObject<YourObject>(json);

I am using below method to parse the string into object
public static T ParseObjectToJSON<T>(string responseText)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
using (MemoryStream stream = new MemoryStream(Encoding.Unicode.GetBytes(responseText)))
{
var rootObject = serializer.ReadObject(stream);
//return Convert.ChangeType(rootObject,typeof(T),System.Globalization.CultureInfo.CurrentCulture.TextInfo);
return (T)rootObject;
}
}
Below is the JSON string which I am trying to parse
https://docs.google.com/document/d/1k81M_UxIrXpHUPQNDUCHDfNw1wY7LM4mAaXjwpYMshk/edit?usp=sharing
The below json string is working
https://docs.google.com/document/d/1uQNwMmSyEZSolyxUVJl6gXzZPr6aRAf_WAogmUvVqt4/edit?usp=sharing
While parsing I get below error
The data contract type 'GAP.Entities.Room' cannot be deserialized because the member 'RoomImage' is not public. Making the member public will fix this error. Alternatively, you can make it internal, and use the InternalsVisibleToAttribute attribute on your assembly in order to enable serialization of internal members - see documentation for more details. Be aware that doing so has certain security implications.
Note- RoomImage is marked public in the entity class. I get this error only when JSON string contains RoomImage array string otherwise no erro.
Any help is highly appreciated.
Thanks

You can download and deserialize an JSON using Newtonsoft.
You have to reference the following DLL, and after that you can try this:
List<Room> deserializedObj = (List<Room>)Newtonsoft.Json.JsonConvert.DeserializeObject(responseText, typeof(List<Room>));
The problem with your json is that if RoomImage has a single element, your service returns it as an object {} not as an array of objects [{}].
So If you want to use type-safe classes in your code(since dynamically accessing is also possible) you should pre-process your json before deserializing. Below code works (of course, as everybody says, using Json.Net)
string json = your__json__string
//PreProcess
var jobj = JObject.Parse(json);
foreach (var j in jobj["ObjectList"])
{
if (!(j["RoomImage"] is JArray))
{
j["RoomImage"] = new JArray(j["RoomImage"]);
}
}
var obj = JsonConvert.DeserializeObject<RootObject>(jobj.ToString());
public class InternalOnly
{
public string RoomId { get; set; }
public string FloorId { get; set; }
}
public class RoomImage
{
public string ImagePath { get; set; }
public string ImageType { get; set; }
public string CreatedDate { get; set; }
public string CreatedId { get; set; }
public string LastUpdateDate { get; set; }
public string LastUpdateId { get; set; }
}
public class ObjectList
{
public string Name { get; set; }
public string EmailAddress { get; set; }
public string RoomListEmailAddress { get; set; }
public string MinimumXCoordinateInMap { get; set; }
public string MinimumYCoordinateInMap { get; set; }
public string MaximumXCoordinateInMap { get; set; }
public string MaximumYCoordinateInMap { get; set; }
public string RoomCapacity { get; set; }
public RoomImage[] RoomImage { get; set; }
public string FloorName { get; set; }
public string CreatedDate { get; set; }
public string CreatedId { get; set; }
public string LastUpdatedDate { get; set; }
public string LastUpdatedId { get; set; }
public string IsRestrictedRoom { get; set; }
public InternalOnly InternalOnly { get; set; }
public object Equipment { get; set; }
}
public class RootObject
{
public List<ObjectList> ObjectList { get; set; }
}
The property RoomImage is public but your class probably isn't.
Make sure the RoomImage class is also marked public. That should solve the problem.
Alternatively use a library like JSON.NET that can do this deserialization without the need for public classes.
