Answer 1

用HttpWebRequest不行吗？要自己解析？

Answer 2

HttpRequest类和HttpResponse类提供了Cookie属性，可以获取你要的信息

Answer 3

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(yourUrl);
req.Method = "GET";
CookieContainer cc = new CookieContainer();
req.CookieContainer = cc;
HttpWebResponse res = (HttpWebResponse)req.GetResponse();
string strR = req.Headers["Cookie"];

Answer 5

楼上的老大，别玩我了，运行结果为
reading...
end.

Answer 6

首先要搞清你的代码运行在服务器端还是客户端啊。楼上的写了那么多代码是在解析Client向Server提交的Cookie，当然拿不到。

Answer 7

当然是客户端...否则哪里来的cookie？

Answer 9

呵呵，还不行吗？试一下用javascript来。
在网页的地址输入栏里输入以下代码：
javascript:alert(document.cookie);
肯定能看到

Answer 10

这段还不行吗？你是在本地客户端读取本地的Cookie吗？
