How to remove d: and __type from JSON response for ASP web service

I've found several solutions for this on the web that are for WCF web service and not ASP web service.

Currently, I'm getting back a JSON response that says:

{"d":[{"__type":"NetworkFuzzWebSvc.Sessions","BaseUri":"http://localbox","SessionId":"43b8716f-40ab-43bf-8311-575c2ecd2730}]}

I need it to return:

{"Sessions":["BaseUri":"http://localbox","SessionId":"43b8716f-40ab-43bf-8311-575c2ecd2730}]}

Here is a copy of the webservice code that I'm using (NetFuzzWebSvc.asmx):

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.Services;
using System.Web.Script.Services;

namespace NetworkFuzzWebSvc
{
    public class Sessions
    {
        public string BaseUri;
        public string SessionId;
    }

    /// <summary>
    /// Summary description for NetFuzzJson
    /// </summary>
    [WebService(Namespace = "http://localbox")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

    [ScriptService]
    public class NetFuzzJson : WebService
    {
        List<Sessions> Sessions = new List<Sessions>
        {
            new Sessions{
                        BaseUri = "http://localbox/", 
                        SessionId="43b8716f-40ab-43bf-8311-575c2ecd2730"
            }
        };

        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public List<Sessions> GetAllSessions()
        {
            return Sessions;
        }
    }

Anyone have a solution to this? Thanks!

I had the same problem, my solution is using Newtone Json Convert:

return JsonConvert.DeserializeObject<List<TestDTO>>(JsonConvert.SerializeObject(result))

you can also using this solution in aspx's web pages (web method)

If you're using ServiceStack.Text JSON Serializer you just need to:

JsConfig.ExcludeTypeInfo = true;

This functionality was automatically added back in v2.28, but the code above keeps that out of the serialization. You can also change this behavior by Type with:

JsConfig<Type>.ExcludeTypeInfo = true;

For remove "d" and "__type":

.svc

[ServiceContract]
public interface ITestService
{
    [OperationContract]
    [WebInvoke(Method = "POST",RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    List<TestDTO> GetAll();
}

.config

<behaviors>
  <endpointBehaviors>
    <behavior name="DebugJSonBehavior" >
      <enableWebScript />
      <!--need set automaticFormatSelectionEnabled attribute -->
      <webHttp automaticFormatSelectionEnabled="true" />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="DebugJSonBehavior" >
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

Js:

    $.ajax({
        type: "POST",
        url: _serviceUrl + "/TestService.svc/GetAll",
        data: "{}",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (dataret) { ... },
        error: function (xmlHttpRequest, textStatus, errorThrown) {... },
        complete: function () { ... }
    });

I don't think that you can. I think that is the format of the json that is returned.

You can try get rid of the ResponseFormat bit and return a string and use

JavaScriptSerializer ser = new JavaScriptSerializer(); 
string json = ser.Serialize(objectClass);
return json;

Or even better use the JSON.Net libraries.

Also look at How to not serialize the __type property on JSON objects for how to remove the __type bit.
