 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";

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

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