        public static string GetResponseText(string url)

        {

            string responseFromServer = null;

            Stream dataStream = null;

            StreamReader reader = null;

            try

            {

                WebRequest request = WebRequest.Create(url);

                request.Credentials = CredentialCache.DefaultCredentials;

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

                if (response.StatusDescription == "OK")

                {

                    try

                    {

                        dataStream = response.GetResponseStream();

                        reader = new StreamReader(dataStream, Encoding.GetEncoding("GB2312"));
