一定要用WebClient吗，WebRequestr用下面的测试通过

private string DownHtml(string url)
{
System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1) Web-Sniffer/1.0.24 ";
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream resStream = response.GetResponseStream();
System.IO.StreamReader sr = new System.IO.StreamReader(resStream, System.Text.Encoding.Default);
return (sr.ReadToEnd());
resStream.Close();
sr.Close();
}
