you're not performing request, once you're done writing request stream itself, perform actual web request:

  string result;    using (httpwebresponse response = (httpwebresponse)request.getresponse())   {        using (streamreader reader = new streamreader(response.getresponsestream()))        {             result = reader.readtoend();        }   } 

also, content type should text/xml or application/xml - api may complaining that. read documentation api , ensure you're sending correct.
