Answer 1

先BS下你的代码没注释，看得我好累
myHeader = response.Headers; 
后面加
myCookie  =  response.GetCookies();
看看行不？
代码不能那么写啊，以后自己都看不懂的

Answer 2

不行啊  不是那个问题  我现在找到毛病了
是这个页面
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://s9.travian.cn/dorf1.php"); 
打开后返回的 cookie 然后 cookie是和http://s9.travian.cn/dorf1.php绑定了 只有再次访问这个地址的时候cookie才带上
访问其他的 就不行寒一个 为什么啊http://s9.travian.cn/dorf1.php 里边 已经包含那个cookie不过 在提交别的页面的时候不带上去 ：（

Answer 3

public CookieContainer myCookie = null; 。为什么不使用static？
