wr.Headers.Add("Accept-Encoding: gzip, deflate");

wr.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Embedded Web Browser from: /; InfoPath.2; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)";

wr.KeepAlive = true;

wr.ServicePoint.Expect100Continue = false;

wr.AllowAutoRedirect = false;

HttpWebResponse wre = wr.GetResponse() as HttpWebResponse;

StreamReader sreader = new StreamReader(wre.GetResponseStream(), Encoding.GetEncoding("GBK"));

string sHtml = sreader.ReadToEnd();

wre.Close();

return sHtml;

}

catch

{

return "";
