I call for to consume json rest web service.
My classes are:
using System.Collections.Generic;
using System.Runtime.Serialization;
namespace WFAEsura
{
[DataContract]
class JsonResponse
{
[DataMember]
public string status { get; set; }
[DataMember]
public Result result { get; set; }
}
class Result
{
public string studentStatus { get; set; }
public List<Results> results { get; set; }
}
class Results
{
public string code { get; set; }
public string description { get; set; }
public double creditAmount { get; set; }
public int timeUnit { get; set; }
public string mark { get; set; }
public bool passed { get; set; }
public string staffMemberName { get; set; }
public List<Results> subResults { get; set; }
}
}
For to create these classes I've used
http://json2csharp.com/
My main class is
var syncClient = new WebClient();
string content = syncClient.DownloadString(baseUrl);
// Create the Json serializer and parse the response
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(JsonResponse));
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(content)))
{
// deserialize the JSON object
var jsonResponse = (JsonResponse)serializer.ReadObject(ms);
}
But in line jsonResponse = (JsonResponse)serializer.ReadObject(ms)
i've invalidDataContractException WFEsura.Result cann't be seralized.
Description is: An unhandled exception of type 'System.Runtime.Serialization.InvalidDataContractException' occurred in System.Runtime.Serialization.dll
Additional information: Type 'WFAEsura.Result' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.
In App.config i've
<startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> </startup>
What am I doing wrong?
