有关webrequest请求basic验证的问题
各位前辈：我想用httpwebrequest 请求一个https连接：
https://gmail.google.com/gmail/feed/atom
可是一直返回401错误，请前辈们帮忙看看是哪里出了问题。。。
WebProxy webProxy = new WebProxy(String.Format("http://{0}:{1}", proxyUrl, port));
string url = String.Format("https://gmail.google.com/gmail/feed/atom", gmailAccount, password);
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
req.Proxy = webProxy;
req.AllowAutoRedirect = true;
req.PreAuthenticate = true;
req.Credentials = new NetworkCredential(gmailAccount, password);
CookieContainer theCookies = new CookieContainer();
req.CookieContainer = theCookies;
req.Method = "Get";
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();//<======401 auth error
Stream respStream = resp.GetResponseStream();
DataSet ds = new DataSet();
ds.ReadXml(respStream);
用httpwatch检查到的https头：

请前辈们帮忙了……
多谢。 --------------------编程问答-------------------- up 大家帮忙啊………………真的不知道怎么回事，网上的都尝试过了…… --------------------编程问答-------------------- 还是没有解决哦…… --------------------编程问答-------------------- 请使用下面的代码:
WebClient objClient = new WebClient();
objClient.Credentials = new System.Net.NetworkCredential("username", "password");
string response = Encoding.UTF8.GetString(objClient.DownloadData("https://mail.google.com/mail/feed/atom"));
我验证过了，不过我这里不需要使用proxy
补充：.NET技术 , C#
