关于网站登录的一些问题（2）谁能解决都行

问题出来了，
我写的提交后的数据：
GET /logon.aspx HTTP/1.1
Content-Type: application/x-www-form-urlencoded
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; CIBA; .NET CLR 2.0.50727)
Host: www.jubaoxiang.com
正常使用IE后提交的数据：
GET /logon.aspx HTTP/1.1
Accept: */*
Accept-Language: zh-cn
Accept-Encoding: gzip, deflate

最后发现没有cookie - -，搞了老半天还是不行 - -，有哪位前辈帮忙看下什么问题么？
--------------------编程问答-------------------- 等
在线等
哎 --------------------编程问答-------------------- 模拟登陆？
很多站点还要带很多参数的
string formatString = "txt_UserName={0}&txt_Password={1}&btn_Login={2}&__VIEWSTATE={3}&__EVENTVALIDATION={4}&txt_PreUrl={5}&__EVENTTARGET={6}&__EVENTARGUMENT={7}&btn_Login.x={8}&btn_Login.y={9}";
--------------------编程问答-------------------- 换个请求试试 用WebRequest
或者HttpWebRequest request = (HttpWebRequest)WebRequest.Create("");
这东西很麻烦的，有时候cookie还需要自己设置 --------------------编程问答-------------------- 经过几天回家的无聊时间，发现是网站的设置cookie时用javascript脚本实现cookie，而代码里面没有执行javascript脚本 --------------------编程问答-------------------- 那就恭喜楼主解决了 --------------------编程问答-------------------- 恭喜恭喜 --------------------编程问答-------------------- 原来已经解决了....... --------------------编程问答-------------------- 我也来看看这是什么情况 --------------------编程问答-------------------- --------------------编程问答--------------------
补充：.NET技术 , C#
