svc webservice response contains extra double qotation

I have a json stored in database in a ntext field, I want to return that in a svc (c#) webservice , webservice is get and response type is string such as below :

    [WebInvoke(Method = "GET",
       ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "gcwbcc/{cityCode}/{key}")]

but in result i get extra double qutation also all double qutions in json converts to \" then I have two problems one is extra double qutation , and second is convertint " to \" in result.

Solution

  • I solve it by changing return type of web method to stream and with writing this simple line of code:

    byte[] resultBytes = Encoding.UTF8.GetBytes(result); WebOperationContext.Current.OutgoingResponse.ContentType = "application/json; charset=utf-8"; return new MemoryStream(resultBytes);
