C#能否使用读取硬盘上IE浏览器的Cookie然后利用这个进行登录

Question

比如我使用IE登录了人人网，然后使用了下次自动登录，所以相关Cookie存储了相应的信息。然后，我自己写了一个WinForm程序，此时，我能否通过C#去读取IE下的Cookie进行分析，然后使用WebClint或者HttpWebRequest进行登录呢？

Answer 1

可以的，读取文件后，自行设置cookies
但现在的浏览器Cookie不好提取的，IE6是可以的

Answer 2

网上找下cookies的内容，可以读取

Answer 3

Cookie一般是以txt文本形式存在的，其内部内容没有加密么？

Answer 4

不记得什么时候写的了，仅供参考，楼主可以搜索一下“IE cookie 格式”

Answer 6

如果你没有选择“记住密码”一类的选项，是没法登录的，CCTV有些骇人听闻了。
