httpwebrequest网页抓取数据乱码

protected void Page_Load(object sender, EventArgs e)
{
string url = "http://www.veryzhun.com/planenumber.html";
string strall = HttpGet(url);
//string srr1 = GetHtmlFromGet(url,Encoding.GetEncoding("gb2312"));
}

    public static string HttpGet(string url)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "GET";
        request.ContentType = "text/html; charset=gb2312";

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        Stream myResponseStream = response.GetResponseStream();
        StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("gb2312"));
        string retString = myStreamReader.ReadToEnd();
        myStreamReader.Close();
        myResponseStream.Close();

        return retString;
    }

            我是新手  不知道为什么还是乱码  希望给位指点

解决方案

request.ContentType = "text/html; charset=gb2312";
你设置这个没用，要看服务器返回的是什么编码的。如果服务器没有指定，那么你各种编码都试下。
