做过自动登录的进~~~~整了一天都没整出来。。。

Question

自动登陆post数据后，可以返回登陆后的url，但用Process.Start（）打开这个url后提示没有的登陆，我想原因是CookieHeader并没有还原回去，有什么方法可以CookieHeader一起提交并打开页面呢？
代码：
                string cookieheader;
                request = WebRequest.Create(url) as HttpWebRequest;
                request.AllowAutoRedirect = true;
                request.Method = "POST";
                request.ContentType = "application/x-www-form-urlencoded";
                CookieContainer cookieCon = new CookieContainer();
                request.ContentLength = data.Length;
                request.CookieContainer = cookieCon;
                outstream = request.GetRequestStream();
                outstream.Write(data, 0, data.Length);
                outstream.Close();                //发送请求并获取相应回应数据
                response = request.GetResponse() as HttpWebResponse;                cookieheader = request.CookieContainer.GetCookieHeader(new Uri(url));
                request.CookieContainer.SetCookies(new Uri(response.ResponseUri.ToString()),cookieheader);                //直到request.GetResponse()程序才开始向目标网页发送Post请求
                System.Diagnostics.Process.Start(response.ResponseUri.ToString());
