        byte[] data = (new ASCIIEncoding()).GetBytes(PostData);
        request.ContentLength = data.Length;
        Stream reqStream = request.GetRequestStream();
        reqStream.Write(data, 0, data.Length);
        reqStream.Close();

        //Get response
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        //Output response to a string            
        String result = "";
        using (Stream responseStream = response.GetResponseStream())
        {
            using (StreamReader reader = new StreamReader(responseStream, Encoding.UTF8))
            {
                result = reader.ReadToEnd();
                reader.Close();
            }
            return result;
        }
