ASP.NET Web API, Unwanted Quotes and Backslashes in Json

Question

NET MVC Web API's, i created a class of Response so that All Routes return same response pattern,

[DataContract]
    public class Response
    {
        [DataMember]
        public string ResponseMessage { get; set; }
        [DataMember]
        public int ResponseCode { get; set; }
        [DataMember]
        public object ResponsePayload { get; set; }        
    }

I am calling APIResponse Method from All routes to return Response, Every time i would Pass Either DataTable or DataSet in object responseObj param of below function, I have to use ADO.NET DB Access layer, :)

private Object APIResponse(object responseObj, string _message = Constants.RESPONSE_MESSAGE_SUCCESS, int code = _RESPONSE_SUCCESS_CODE)
        {

            Response _response = new Response();
            _response.ResponsePayload = responseObj;
            _response.ResponseMessage = _message;
           _response.ResponseCode = code;

            return Newtonsoft.Json.JsonConvert.SerializeObject(_response);
        }

if my responseObj param is of type DataSet, than i get Unwanted Quotes and Backslashes (Like in PHP if Magic Quotes are enable on Server) which produce a invalid JSON, Can you please help me in fixing this issue, to remove these slashes,

Sample JSON:

"{\"ResponseMessage\":\"Success\",\"ResponseCode\":200,\"ResponsePayload\":{\"StatusList\":[{\"StatusId\":1,\"Status\":\"To Be Dispatched\", ...........

In case of DataTable it create correct Json, only creating invalid Json in Case of DataSet, — shary

Is that definitely the returned JSON and not just a Visual Studio debugger "quickview" representation of it? (Which will add the backslashes.) — Snixtor

Why are you reinventing HTTP on top of HTTP? HTTP already has HttpStatusCode and ReasonPhrase for this purpose. — Darrel Miller

you should define your Get like this

public IEnumerable<string> Get(int id1)

public List<Response> Get( int id1)

instead of this

public string Get(int id1)
