                request.Headers.Set("Pragma", "no-cache");                HttpWebResponse response = (HttpWebResponse)request.GetResponse();                Stream streamReceive = response.GetResponseStream();                Encoding encoding = Encoding.GetEncoding("GB2312");
                //StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("gb2312"));                 StreamReader streamReader = new StreamReader(streamReceive, encoding);

 Encoding encoding = Encoding.GetEncoding("UTF-8");
