在这段代码中工作............

        try
        {

            var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://localhost/Services/BasicService.svc/MemberRegistration");

            httpWebRequest.Method = "POST";
            httpWebRequest.ContentType = "application/json";
            using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
            {
                var NAME= "adss";
                var LoginTypes = 1;
                var Passwords = "asasaytsasasa"; var MobileNo = "23456fd587"; var imeino = "e35tfgg5"; var LoginIDs = "abfcsdskghj@google.com";

                string jSonData = "{" + "\"Name\":\"" + NAME + "\"," + "\"LoginType\":\"" + LoginTypes + "\"," + "\"Password\":\"" + Passwords + "\"," + "\"Mobile\":\"" + MobileNo + "\"," + "\"imei\":\"" + imeino + "\"," + "\"LoginID\":\"" + LoginIDs + "\"}";

                streamWriter.Write(jSonData);
                streamWriter.Flush();
                streamWriter.Close();

                var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
                using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
                {
                    var result = streamReader.ReadToEnd();
                }

            }


        }
        catch
        {

        }
