//myHttpWebRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0;)";
myHttpWebRequest.CookieContainer = new CookieContainer(); //暂存到新实例
cookies = myHttpWebRequest.CookieContainer; //保存cookies
myHttpWebRequest.GetResponse().Close();
string cookiesstr = myHttpWebRequest.CookieContainer.GetCookieHeader(myHttpWebRequest.RequestUri); --------------------编程问答-------------------- 那样写不行吧,应该这样:
