代码：

/// 
        /// Get网址，返回网页源码         /// 
        /// 需要Get的网址。例：http://www.baidu.com        /// 目标网页的编码集。便：utf-8，gb2312        /// 
              public string GetWeb(string webUrl, string charset)        {            WebRequest request = WebRequest.Create(webUrl);            WebResponse response = request.GetResponse();            Stream s = response.GetResponseStream();            StreamReader sr = new StreamReader(s, Encoding.GetEncoding(charset));//编码格式             string webHtml =  sr.ReadToEnd();//返回Html            sr.Dispose();            sr.Close();            s.Dispose();            s.Close();            return webHtml;        }

调用：

MessageBox.Show(GetWeb(", "gb2312"));

MessageBox.Show(GetWeb(", "utf-8"));
