Get the json format also in C# coding as string.

public JsonResult FileUploadDetails(HttpPostedFileBase[] Files,string request)
       {

           //Stream req = Request.InputStream;
           //string reqparm = Request.QueryString["request"];
           //req.Seek(0, System.IO.SeekOrigin.Begin);
           //var jsonStr = new StreamReader(reqparm).ReadToEnd();
           JObject obj = JObject.Parse(request);
            .................
              ...............
       }
