  try
            {
                string sHtml = "";
                CookieContainer cc = new CookieContainer();
                string url = "http://news.baidu.com/ns?word=%22%C3%C0%B5%C4%22+%22%B1%F9%CF%E4%22&ie=gb2312&bs=%22%C3%C0%B5%C4%22+%22%B1%F9%CF%E4%22&sr=0&cl=2&tn=newsdy&ct=1&clk=sortbyrel&bt=0&et=0&rn=100&class=0";
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
                //req.MaximumAutomaticRedirections = 1000;
                //req.Proxy   =   new   WebProxy("myproxyserveraddree",8080);   
                req.CookieContainer = cc;
                //req.UserAgent   =   "Mozilla/4.0   (compatible;   MSIE   6.0;   Windows   NT   5.2;   .NET   CLR   1.1.4322)";                   HttpWebResponse result = (HttpWebResponse)req.GetResponse();                StreamReader reader = new StreamReader(result.GetResponseStream(),                System.Text.Encoding.GetEncoding("GB2312"));
                sHtml = reader.ReadToEnd();
                reader.Close();
                result.Close();                StreamWriter sw = new StreamWriter("xinhua.html", false, System.Text.Encoding.GetEncoding("GB2312"));
                sw.Write(sHtml);
                sw.Close();
            }
            catch(Exception ex)
            {
