how to Deserialize Json response from WCF Restful Service? - json

Question

I want to deserialize a Json response into my class object. I have created a WCF Restful Service, and from client using proxy object I'm calling a service method which return me a json. Now I want to convert that json into my class object.
My service is as follow:
[OperationContract]
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped,
UriTemplate = "GetProject/{projectID}")]
tblProject GetProject(String projectID);
Implementations:
public tblProject GetProject(String projectID)
{
tblProject pro = new tblProject();
pro = DAL.ProjectDAL.GetProject(Convert.ToInt32(projectID));
return pro;
}
and from controller in MVC I'm making request as:
public ActionResult Index()
{
var request = (HttpWebRequest)WebRequest.Create("http://localhost:8733/Design_Time_Addresses/RestServiceLibrary.RESTService/REST_ProjectService/getproject/2");
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Stream stream = response.GetResponseStream();
StreamReader reader = new StreamReader(stream);
string txtResult = reader.ReadToEnd();
return view();
}
and when I run I'm getting response as:
and when I call through a proxy method I got exception:
but my endpoints are there in config as,

Answer 1

you can use javascriptserializer
string s = "YouJsonText";
var serializer = new JavaScriptSerializer();
var result = serializer.Deserialize(s);
//or
YouCustomClass res = serializer.Deserialize<YouCustomClass>(sb.ToString());
Also, you can use CustomJsonConverter like this:
public class YouCustomClassConverter : JavaScriptConverter
{
public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
{
throw new NotImplementedException();
}
public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer)
{
throw new NotImplementedException();
}
//and first you need register type, which you want Deserialize
public override IEnumerable<Type> SupportedTypes
{
get { return new[] { typeof(YouCustomClass ) }; }
}
}
//and then example of using JavaScriptSerializer with custom converter
var ser = new JavaScriptSerializer();
ser.RegisterConverters(new JavaScriptConverter[] { new YouCustomClassConverter() });
try
{
YouCustomClass obj = ser.Deserialize(jsonString);
}
Note: you need use using System.Web.Script.Serialization;

class GetProjectResultWrapper
{
public GetProjectResult GetProjectResult{ get; set; }
}
class GetProjectResult
{
public string id {get;set;}
.....
......
}
JavaScriptSerializer ser = new JavaScriptSerializer();
GetProjectResultWrapper response = ser.Deserialize<GetProjectResultWrapper>(sb.ToString());
response .GetProjectResult;
