Answer 1

我觉得是cookie那个地方的问题，但是确实不清楚是哪的问题

Answer 2

request.CookieContainer = new CookieContainer();
request.CookieContainer.Add(response.Cookies);这两个地方有错。
应该是//定义一个全局变量 mycookie
private CookieContainer _mycookie = new CookieContainer();
public CookieContainer mycookie { get { return _mycookie; } set { _mycookie = value; } }
//mycookie，应该处于一个不会湮灭的进程中；
//先要GET下，获取Cookie；而后直接使用就行了；
request.CookieContainer = mycookie;
//不需要CookieContainer.Add()；更何况是Add一个空的Cookies;
request.CookieContainer = mycookie;
//这样就行了，CookieContainer，自己自动添加和更新的。

Answer 3

其实我有个问题。为什么你自己可以连续回复4次。我记得只能回复3次对于问题提供的建议1.用httpanalyzerfullv   分析你自己的程序post  的数据  和  cookie 情况与  正式情况的  post 数据   与 cookie是否相同
如果不相同看哪里不一样.然后改过来喽

Answer 4

request.CookieContainer.Add(response.Cookies);
....
request = (HttpWebRequest)WebRequest.Create("http://localhost/wordpress/wp-admin/post.php");
这时候，已经是一个新的webrequest了
request.CookieContainer = new CookieContainer();这时候cookie集合是空的，要把之前获取到的add进来才行，不然你刚才登陆那一步，等于没用~~

Answer 5

先发送请求才有cookie呀，没发送请求哪来的cookie
