Return Json, but it includes backward slashes "\", which I don't want

Question

I use MVC4 web-api, c#, and want to return Json using Json.net.

The problem is it comes with "backward slashes".

I also added this code to Global.asax. GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();

Here is what it returns:

"{\"cid\":1,\"model\":\"WT50JB\",\"detail\":\"sdf??\",\"unit\":2,\"time_in\":\"2012-12-11T19:00:00\",\"time_out\":\"2012-12-12T13:00:06.2774691+07:00\",\"time_used_dd\":0.0,\"time_used_hh\":0.0}" 

So what I want to see is this: {"cid":1,"model":"WT50JB","detail":"sdf??","unit":2,"time_in":"2012-12-11T19:00:00","time_out":"2012-12-12T13:08:50.5444555+07:00","time_used_dd":0.0,"time_used_hh":0.0}

Here is JsonConvertor

string json = JsonConvert.SerializeObject(myObj); 

Answer 1

I had the same issue, until just a few moments ago. Turns out that I was "double serializing" the JSON string. I use a jQuery $.getJson( AJAX call to a JsonResult controller action. And because the action builds a C# Generic List<t> I thought that I had to use JSON.net/NewtonSoft to convert the C# Generic List<t> to a JSON object before returning the JSON using the following:

return Json(fake, JsonRequestBehavior.AllowGet); 

I didn't have to use the JsonConvert.SerializeObject( method after all, evidently this return will conver the serialization for us.

Hope it helps you or someone else too.

i found the solution here it is

return new HttpResponseMessage()  {     Content = new StringContent(json, System.Text.Encoding.UTF8, "application/json") };
