                //System.GC.Collect();
                System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

                HttpWebRequest hr = (HttpWebRequest)WebRequest.Create(URL);

                hr.UserAgent = "Mozilla/5.0 (Windows NT 5.2; rv:42.0) Gecko/20100101 Firefox/42.0";
               
                hr.Headers.Add("Accept-Encoding", "gzip, deflate");
                hr.Method = "GET";
                hr.ContentType = "text/html;charset=GBK";
                hr.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
                hr.Referer = sRefer;
                hr.KeepAlive = true;
                hr.ReadWriteTimeout = 10000;
                hr.Timeout = 15000;
                hr.CookieContainer = new CookieContainer();
                HttpWebResponse wsp = (HttpWebResponse)hr.GetResponse();

这个时候wsp.Cookies.Count为0。

怎么解决下呢？实现成功获取页面Cookie值
