Answer 1

//获取网页源代码
private string GetHtmlCode(string url, Encoding encoding)
{
    System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
    request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)";
    System.Net.WebResponse response = request.GetResponse();
    System.IO.Stream resStream = response.GetResponseStream();
    System.IO.StreamReader sr = new System.IO.StreamReader(resStream, encoding);
    string html = (sr.ReadToEnd());
    resStream.Close();
    sr.Close();
    return html;
}
//调用
richTextBox2.Text = GetHtmlCode("http://www.zhantai.com/", Encoding.GetEncoding("gb2312"));

Answer 2

StreamReader rdr =new StreamReader(rsp.GetResponseStream(),Encoding.GetEncoding("GB2312"));
检查HTTP头，ContentType

Answer 3

 /// <summary>
        /// 得到整个网页的源码
        /// </summary>
        /// <param name="Url"></param>
        /// <returns></returns>
        public static string _GetHtml(string Url)
        {            Stream MyInStream = null;
            string Html = "";
            try
            {
                HttpWebRequest MyRequest = (HttpWebRequest)WebRequest.Create(Url);
                HttpWebResponse MyResponse = (HttpWebResponse)MyRequest.GetResponse();                MyInStream = MyResponse.GetResponseStream();                Encoding encode = System.Text.Encoding.UTF8;
                StreamReader sr = new StreamReader(MyInStream, encode);                Char[] read = new Char[256];
                int count = sr.Read(read, 0, 256);
                while (count > 0)
                {
                    String str = new String(read, 0, count);
                    Html += str;
                    count = sr.Read(read, 0, 256);
                }
            }
            catch (Exception)
            {
                Html = "错误";
            }
            finally
            {
                if (MyInStream != null)
                {
                    MyInStream.Close();
                }
            }
            return Html;
