我使用webbrower构建了一个C＃应用程序，以便在使用https并登录的特定网站上自动保存财务活动。用户手动登录应用程序的Web浏览器并导航到正确查看活动的页面后，用户可以单击工具以保存其控制下的所有活动，也可以选择保存特定时段或所有时段。
问题是网站确实使用cookies，不允许打开另一个webbrowser;尽管根据我使用webbrowser
的观察结构构建了正确的网址，似乎拒绝了http请求尝试保存所有可用帐户的所有活动的非工作代码：

如何才能将HtmlDocumemt cookie从webbrowser正确转换为System.net.cookie？提前thx，非常感谢任何提示或参考。
我的主要工作是系统管理，一些数据库管理以及增加或添加小应用程序的小方面职责。所以请原谅我在httpsquest中的c＃.net esp中的弱点 我已经做了很多谷歌搜索，但未能找到合适的关键词来获得结果。
我也在webbrowser中尝试过不同的方法，但是我无法使用webbrowser文档完成事件来处理有状态执行的复杂性。即使我在那里取得成功，维持也是一场噩梦。
