I have been trying to get this json to deserialize for two days now using RestSharp. I have gone through the RestSharp github site, looked at countless examples, and spent much time here on Stack Overflow to try and find the answer to no avail. My code had previously worked perfectly but the vendor changed their API version and I was forced to do an update to keep using the application for my legal practice. My json is as follows(client info has been removed and replaced with generic info):
{
"data":[
{
"id":1035117666,
"client":
{
"id":905422394,
"name":"client1"
},
"display_number":"11-00012",
"description":"General",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2011-12-14",
"close_date":null,
"billing_method":"hourly"
},
{
"id":1035117768,
"client":
{
"id":905422506,
"name":"client2"
},
"display_number":"12-00037",
"description":"HOA",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2012-08-07",
"close_date":null,
"billing_method":"hourly"
}
],
"meta":
{
"paging":
{
"next":"https://app.goclio.com/api/v4/matters.json?fields=id%2C+client%7Bid%2C+name%7D%2C+display_number%2C+description%2C+practice_area%7Bid%2C+name%7D%2C+status%2C+open_date%2C+close_date%2C+billing_method&limit=2&page_token=BAh7BjoLb2Zmc2V0aQc%3D--b1ea3eba20c8acefbcdfc7868debd1e0ee630c64&status=Open"
},
"records":91
}
}
I built the following schema within my c# code:
public class MatterList
{
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
public class Meta
{
public Paging paging { get; set; }
public int records { get; set; }
}
public class Paging
{
public string previous { get; set; }
public string next { get; set; }
}
[DeserializeAs(Name = "data")]
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
public class PracticeArea
{
public int id { get; set; }
public string name { get; set; }
}
public class Client
{
public int id { get; set; }
public string name { get; set; }
}
When I run the RestSharp deserialize method I am sending the result to an object of type MatterList using the following line of code
MatterList matterList = jsonHandler.Deserialize<MatterList>(response);
I have so far attempted to deserialize without the Meta or Paging POCO classes with the accompanying change to the MatterList class (taking out the Meta property).
I have tried with and without the [DeserializeAs(Name="data")] directive.
I have tried to set the RootElement of the json response prior to deserialization.
I have tried to shorthand the deserialization by combining it with the Execute request code
IRestResponse<MatterList> matterList = client.Execute<MatterList>(request);
I have created a container class called MatterContainer which I placed between MatterList and Matter classes in the schema:
public class MatterList
{
public List<MatterContainer> matters { get; set; }
}
public class MatterContainer
{
public Matter matter { get; set; }
}
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
I know I am getting the json response back from the server correctly so my request is proper and MatterList is not null after deserialization. The problem is that I cannot get the deserialization to actually populate the List matters within the MatterList class.
I have been looking at this off and on for two days and cannot get past this hurdle. If anyone sees what I did wrong I would greatly appreciate the insight, I am at a point where I cannot progress further with my application.
Thanks!
I think your [DeserializeAs(Name = "data")] attribute is in the wrong place. Try putting it in the root class instead:
public class MatterList
{
[DeserializeAs(Name = "data")]
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
alternatively, try renameing that property to data

I don't know if there is an existing name for that case, but I'm trying to retrieve data from NASA API (https://api.nasa.gov/) and I have a simple challenge to catch a list of objects near earth. Here is the JSON response I have from the GET request I do to "https://api.nasa.gov/neo/rest/v1/feed?...."
{
"links": {
"next": "http://www.neowsapp.com/rest/v1/feed?start_date=2021-07-04&end_date=2021-07-04&detailed=false&api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym",
"prev": "http://www.neowsapp.com/rest/v1/feed?start_date=2021-07-02&end_date=2021-07-02&detailed=false&api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym",
"self": "http://www.neowsapp.com/rest/v1/feed?start_date=2021-07-03&end_date=2021-07-03&detailed=false&api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym"
},
"element_count": 6,
"near_earth_objects": {
"2021-07-03": [
{
"links": {
"self": "http://www.neowsapp.com/rest/v1/neo/3701710?api_key=NjgpxgSbYHXyFSBI3HaOhRowtjMZgAKv2t4DMRym"
},
"id": "3701710",
"neo_reference_id": "3701710",
"name": "(2014 WF497)",
"nasa_jpl_url": "http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=3701710",
"absolute_magnitude_h": 20.23,
"estimated_diameter": {
"kilometers": {
}
And that's the way it is built in Visual Studio (using the Special Paste option for JSON)
public class NearEarthObject
{
public Links links { get; set; }
public int element_count { get; set; }
public Near_Earth_Objects near_earth_objects { get; set; }
}
public class Links
{
public string next { get; set; }
public string prev { get; set; }
public string self { get; set; }
}
public class Near_Earth_Objects
{
public _20210703[] _20210703 { get; set; }
}
public class _20210703
{
public Links1 links { get; set; }
public string id { get; set; }
public string neo_reference_id { get; set; }
public string name { get; set; }
public string nasa_jpl_url { get; set; }
public float absolute_magnitude_h { get; set; }
public Estimated_Diameter estimated_diameter { get; set; }
public bool is_potentially_hazardous_asteroid { get; set; }
public Close_Approach_Data[] close_approach_data { get; set; }
public bool is_sentry_object { get; set; }
}
The question is, inside of the element "near_earth_objects", there is an element called "2021-07-03" (the date of the data I requested), the problem is that I am trying to include it into a DataGridView made in .NET C# (Windows Forms, but that doesn't matters here, I think) and the user wants to get the information by date. So, "2021-07-03" is a valid member just for one day, and the user should be able to get data from multiple days.
So, is there a way in C# to get all child objects inside of near_earth_objects without knowing their names since there will be the option to search for asteroids from date X to Y in my application?
Using System.Text.Json
The API response will map to the following classes
public class Neo
{
public Links Links { get; set; }
public int ElementCount { get; set; }
public Dictionary<string, List<NearEarthObject>> NearEarthObjects { get; set; }
}
public class Links
{
public string Next { get; set; }
public string Prev { get; set; }
public string Self { get; set; }
}
public class NearEarthObject
{
public Links Links { get; set; }
public string Id { get; set; }
public string Name { get; set; }
// Other properties
}
The NearEarthObjects is simply a Dictionary, where the key is the formatted date and value is a List containing NearEarthObject
The PropertyNamingPolicy will allow us to support the API's underscore property naming convention.
public class UnderscoreNamingPolicy : JsonNamingPolicy
{
public override string ConvertName(string name)
{
return name.Underscore();
}
}
Example usage
// using using System.Text.Json;
var response = await new HttpClient().GetStringAsync(url);
var neo = JsonSerializer.Deserialize<Neo>(response, new JsonSerializerOptions
{
PropertyNamingPolicy = new UnderscoreNamingPolicy()
});
foreach(var neos in neo.NearEarthObjects)
{
Console.WriteLine(neos.Key);
}
use System.Text.Json, JsonNamingPolicy
demo code
public class DynamicNamePolicy : JsonNamingPolicy
{
public override string ConvertName(string name)
{
var today = DateTime.Today.ToString("yyyy-MM-dd");
if (name.Equals("DateData")) //model property name
return today; //convert to json string property name
return name;
}
}
//data deserialize
string data = ""; //json string
var obj = JsonSerializer.Deserialize<NearEarthObject>(data, new JsonSerializerOptions
{
PropertyNamingPolicy = new DynamicNamePolicy(),
});
I have a json file, where i have to validate a json attribute element value based on another json element attribute value. But if there json elements with the same name. It always takes the last value always instead of parsing the json data fully. Please guide me.
Below the sample json file
{
"PLMXML":{
"language":"en-us",
"author":"Developer",
"date":"2020-05-22",
"traverseRootRefs":"#id6",
"Operation":{
"id":"id21",
"subType":"BS4_BaOP",
"catalogueId":"70700000209604"
},
"Operation":{
"id":"id28",
"subType":"BS4_BaOP",
"catalogueId":"70700000209603"
},
"OperationRevision":{
"id":"id6",
"subType":"BS4_BaOPRevision",
"masterRef":"#id21",
"revision":"A1"
}
}
}
And below the code which im trying to use
public void Readjsonfile(string jsondata)
{
var message = JsonConvert.DeserializeObject<plmxmldatamodel>(jsondata);
if (String.Equals(message.PLMXML.traverseRootRefs.Substring(1), message.PLMXML.OperationRevision.id))
{
Console.WriteLine("Condtion1");
if (String.Equals(message.PLMXML.OperationRevision.masterRef.Substring(1), message.PLMXML.Operation.id))
{
Console.WriteLine("Condition_2");
//Do something based on the condtion
}
}
}
public class Operation
{
public string id { get; set; }
public string subType { get; set; }
public string catalogueId { get; set; }
}
public class OperationRevision
{
public string id { get; set; }
public string subType { get; set; }
public string masterRef { get; set; }
}
public class PLMXML
{
public string language { get; set; }
public string author { get; set; }
public string date { get; set; }
public string traverseRootRefs { get; set; }
public Operation Operation { get; set; }
public OperationRevision OperationRevision { get; set; }
}
public class plmxmldatamodel
{
public PLMXML PLMXML { get; set; }
}
When i try to dedug this in the second if condtion, the value for message.PLMXML.Operation.id is always id28 , because of which second if condition fails. While the first if condition is passed as there is only one message.PLMXML.OperationRevision.id. i wanted behaviour where it would check complete json data and check if message.PLMXML.Operation.id with value id21 is present or not , So my data gets passed. Please kindly guide me here.I am very new to C# here.
From my observation you have couple of issues.
What happen you have double keys, and your parser taking the last value not the first one.
First of all your json should be corrected. I assume you have access to change your json and operation should be an array like follow:
{
"PLMXML":{
"language":"en-us",
"author":"Developer",
"date":"2020-05-22",
"traverseRootRefs":"#id6",
"Operations":[
{
"id":"id21",
"subType":"BS4_BaOP",
"catalogueId":"70700000209604"
},
{
"id":"id28",
"subType":"BS4_BaOP",
"catalogueId":"70700000209603"
}
],
"OperationRevision":{
"id":"id6",
"subType":"BS4_BaOPRevision",
"masterRef":"#id21",
"revision":"A1"
}
}
}
When array in place than use an online tool like to validate your json and use this tool to create a model.
Your model will be like this:
public partial class PlmxmlDataModel
{
[JsonProperty("PLMXML")]
public Plmxml Plmxml { get; set; }
}
public partial class Plmxml
{
[JsonProperty("language")]
public string Language { get; set; }
[JsonProperty("author")]
public string Author { get; set; }
[JsonProperty("date")]
public DateTimeOffset Date { get; set; }
[JsonProperty("traverseRootRefs")]
public string TraverseRootRefs { get; set; }
[JsonProperty("Operations")]
public Operation[] Operations { get; set; }
[JsonProperty("OperationRevision")]
public OperationRevision OperationRevision { get; set; }
}
public partial class OperationRevision
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("subType")]
public string SubType { get; set; }
[JsonProperty("masterRef")]
public string MasterRef { get; set; }
[JsonProperty("revision")]
public string Revision { get; set; }
}
public partial class Operation
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("subType")]
public string SubType { get; set; }
[JsonProperty("catalogueId")]
public string CatalogueId { get; set; }
}
And your method like this:
public void Readjsonfile(string jsondata)
{
var message = JsonConvert.DeserializeObject<PlmxmlDataModel>(jsondata);
if (String.Equals(message.Plmxml.TraverseRootRefs.Substring(1), message.Plmxml.OperationRevision.Id))
{
Console.WriteLine("Condtion1");
if (String.Equals(message.Plmxml.OperationRevision.MasterRef.Substring(1), message.Plmxml.Operations[0].Id))
{
Console.WriteLine("Condition_2");
//Do something based on the condtion
}
}
}
Now in your method I am looking for array index 0 with contain id 28, but if you are look for id 28 in any of the array then you can do some thing like:
if (message.Plmxml.Operations.Any(e => e.Id == message.Plmxml.OperationRevision.MasterRef.Substring(1)))
I'm running into an issue when I am trying to deserialize a webAPI GET call that returns a JSON object. The issue being one particular property is always null after being deserialized.
The JSON object looks like this:
{
"status":"OK",
"masterlist":{
"session":{
"session_id":intValue,
"session_name":"stringValue"
},
"0":{
"bill_id":intValue,
"number":"stringValue",
"change_hash":"stringValue",
"url":"stringValue",
"status_date":"dateValue",
"status":"stringValue",
"last_action_date":"dateValue",
"last_action":"stringValue",
"title":"stringValue",
"description":"stringValue"
},
"1":{
"bill_id":intValue,
"number":"stringValue",
"change_hash":"stringValue",
"url":"stringValue",
"status_date":"dateValue",
"status":"stringValue",
"last_action_date":"dateValue",
"last_action":"stringValue",
"title":"stringValue",
"description":"stringValue"
},
"2":{
"bill_id":intValue,
"number":"stringValue",
"change_hash":"stringValue",
"url":"stringValue",
"status_date":"dateValue",
"status":"stringValue",
"last_action_date":"dateValue",
"last_action":"stringValue",
"title":"stringValue",
"description":"stringValue"
}
}
}
As you can see the second property of masterlist isn't an array, that would make life too easy... But it looks more like a collection of name/value pairs. I have reviewed This post and the associated one listed within but they both pertain to if the name/value pair where at the root level where mine is not.
My method that I am using to deserialize is:
BillMaster billMasterList = new BillMaster();
using (HttpClient client = new HttpClient())
{
string json = Get("&op=getMasterList&state=TN");
billMasterList = JsonConvert.DeserializeObject<BillMaster>(json);
}
And the model classes the deserializer is binding to:
public class BillMaster
{
public string Status { get; set; }
public BillMasterList masterlist { get; set; }
}
public class BillMasterList
{
public BillMasterList_Session session { get; set; }
public Dictionary<int, BillMasterList_Array> BillMasterList_Array { get; set; }
}
public class BillMasterList_Array
{
public int bill_id { get; set; }
public string number { get; set; }
public string change_hash { get; set; }
public string url { get; set; }
public string status_date { get; set; }
public string status { get; set; }
public string last_action_date { get; set; }
public string last_action { get; set; }
public string title { get; set; }
public string description { get; set; }
}
When I run the code I don't throw any errors and I have values in my object except for BillMasterList_Array, that is always null. I'm obviously not doing something right but what it is alludes me.
I want to bind the Json data to the repeater I know only one process that is converting the Json data to data table and then binding data but here I am receiving multilevel json data i do't know how to convert them to data table
input json data:
{"apiAvailableBuses":
[{"droppingPoints":null,"availableSeats":40,"partialCancellationAllowed":false,"arrivalTime":"01:00 AM","cancellationPolicy":"[{\"cutoffTime\":\"1\",\"refundInPercentage\":\"10\"},{\"cutoffTime\":\"2\",\"refundInPercentage\":\"50\"},{\"cutoffTime\":\"4\",\"refundInPercentage\":\"90\"}]","boardingPoints":[{"time":"07:40PM","location":"K.P.H.B,Beside R.S Brothers","id":"2238"}],"operatorName":"Apple I Bus","departureTime":"8:00 PM","mTicketAllowed":false,"idProofRequired":false,"serviceId":"6686","fare":"1000","busType":"Hi-Tech A/c","routeScheduleId":"6686","commPCT":9.0,"operatorId":203,"inventoryType":0},

I am trying to convert it to data table by
public void getavailablebuses()
{
string url = string.Format(HttpContext.Current.Server.MapPath("files/getavailablebuses.json"));
using (WebClient client = new WebClient())
{
string json = client.DownloadString(url);
var result = JsonConvert.DeserializeObject<RootObject>(json);
string mm = JObject.Parse(json).SelectToken("apiAvailableBuses").ToString();
// var boardingpoint = JObject.Parse(mm).SelectToken("boardingPoints").ToString();
var Availablebuses = JObject.Parse(json).SelectToken("apiAvailableBuses").ToString();
DataTable dt = (DataTable)JsonConvert.DeserializeObject(Availablebuses, (typeof(DataTable)));
}
public class apiresult

}
public class cancellationPolicy

}
Here in the data table I am unable to get the boarding points, dropping points and cancellation policy
if I load cancellation policy as list or JObject I am getting error
so here I am loading cancellation policy as string.
but I am unable to load boarding points and dropping points.
Please help with this I am scratching my head from two days. Thanks in advance
"I know only one method to bind data to a repeater i.e data table." So this is a perfect opportunity to learn other ways, wouldn't you say?
Why don't you work with the result of JsonConvert.DeserializeObject<RootObject>(json);? This is a RootObject that has a property called apiAvailableBuses which seems to be exactly what you need to bind to your repeater, no?
By the way, a bit of code review:
apiresult and apiAvailableBuses violate Microsoft's rules WRT class names: those should be in PascalCase. Same for the properties of apiresult, e.g. message and success. Same for the properties of apiAvailableBuses.
RootObject has a public field: apiStatus. That probably needs to be a a property with a getter/setter.
Moreover, apiAvailableBuses is plural, which is incorrect, since the data therein is of only one bus. Same for boardingpoints: the class contains data for a single point, not multiple.
Be consistent: if you use string, then also use bool and not Boolean.
I'm writing here because I think I used all resources I could get. There must be something terribly wrong with my abstraction/approach because I cannot
make it work properly. Task is quite simple - I need to iterate through nested list(??) generated from json input(or maybe I'm doing it wrong from the scratch).
Using jquery with this json works great but this time I need to process data on the server side.
I got json input(example extract below):
{
"services":[
{
"service_status":"CRITICAL",
"service_host":{
"host_status":2,
"host_address":"192.168.1.12",
"host_name":"test1app_srv",
"host_problem_has_been_acknowledged":0,
"host_has_comments":0,
"host_notifications_enabled":1,
"host_checks_enabled":1,
"host_is_flapping":0,
"host_scheduled_downtime_depth":0,
"host_notes_url":"",
"host_action_url":"",
"host_icon_image":"server.gif"
},
"service_description":"test1app_srv",
"service_problem_has_been_acknowledged":0,
"service_has_comments":0,
"service_accept_passive_service_checks":1,
"service_notifications_enabled":1,
"service_checks_enabled":1,
"service_is_flapping":0,
"service_scheduled_downtime_depth":0,
"service_notes_url":"",
"service_action_url":"",
"service_icon_image":"services.gif",
"service_state_duration":" 0d 0h 2m 7s",
"service_last_check":"04-27-2013 23:49:55",
"service_current_attempt":1,
"service_max_attempts":1,
"service_plugin_output":"CRITICAL - Throughput : Threshold '600' failed for value 720"
},
{}
]
}
from which, using http://json2csharp.com/ I've generated c# classes:
public class ServiceHost
{
public int host_status { get; set; }
public string host_address { get; set; }
public string host_name { get; set; }
public int host_problem_has_been_acknowledged { get; set; }
public int host_has_comments { get; set; }
public int host_notifications_enabled { get; set; }
public int host_checks_enabled { get; set; }
public int host_is_flapping { get; set; }
public int host_scheduled_downtime_depth { get; set; }
public string host_notes_url { get; set; }
public string host_action_url { get; set; }
public string host_icon_image { get; set; }
}
public class Service
{
public string service_status { get; set; }
public ServiceHost service_host { get; set; }
public string service_description { get; set; }
public int service_problem_has_been_acknowledged { get; set; }
public int service_has_comments { get; set; }

public int service_scheduled_downtime_depth { get; set; }
public string service_notes_url { get; set; }
public string service_action_url { get; set; }
public string service_icon_image { get; set; }
public string service_state_duration { get; set; }
public string service_last_check { get; set; }
public int service_current_attempt { get; set; }
public int service_max_attempts { get; set; }
public string service_plugin_output { get; set; }
}
public class NagiosRootObject
{
public List<Service> services { get; set; }
}
I managed to get the NagiosRootObject.services content but I cannot access values from Service.service_host.
I focused on an approach utilizing
NagiosRootObject obj = JsonConvert.DeserializeObject<NagiosRootObject>(json);
I have all above and I'm using Json.NET from http://json.codeplex.com.
I have tried hints from
Deserializing JSON object into a C# list
Deserialize JSON array(or list) in C#
C# - How to implement IEnumerator on a class
Deserialize Json to Class that implements Ienumerable in Asp.net
and few related but witho no luck.
Knowing that there is so many tutorials and not being able to make use of it makes me really sad..
Help would be appreciated. This post is the last resort for this task... I need serious tips. Thank You
Using json.NET the following code works: (after putting your json in a file called 'json.txt')
using (var reader = File.OpenText("json.txt"))
{
var ser = JsonSerializer.Create(null);
var jReader = new JsonTextReader(reader);
var grp = ser.Deserialize<NagiosRootObject>(jReader);
}
However, the list is populated by two objects, and in the 2nd one all the values are null. This is because you have an empty element {} in your json.
Edit: Your code works just as well in my test, so no need to change it.
Have you tried:
var obj = new JavaScriptSerializer().Deserialize<NagiosRootObject>(jsonString);
If you want to parse this json in server then it is better to parse this json into XML and utilize that xml to traverse. In server side coding xml traversing is easy. Especially in C#.
Convert the json into XMl or wise versa using newtonsoft dll. The code to parse json to XMl is
XmlDocument doc = (XmlDocument)JsonConvert.DeserializeXmlNode(json);
Dpwnload the dll from the link

I hope this will help you.
