推荐答案

您可以像使用HTTP一样完全使用HTTPS，使用类System.Net.HttpWebRequest.如果下面的MSDN页面，请参见说明:您应该使用System.Net.WebRequest.Create来获取HttpWebRequest的实例，而不是HttpWebRequest构造函数；具体的运行时类型将从URL模式中找出(在您的情况下为https://).

参见:
http://msdn.microsoft.com/en-us/library/system.net. httpwebrequest.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.net. webrequest.aspx [ ^ ](请参阅HTTP的代码示例，但使用"https://...").

我不知道您的身份验证页面的详细信息，但是如果这是带有用户名/密码的常规Web表单，则可以使用"POST"方法登录.
这可以给你一个主意:

You can work with HTTPS exactly as with HTTP, using the class System.Net.HttpWebRequest. See the explanation if the MSDN page below: you should use System.Net.WebRequest.Create to get the instance of HttpWebRequest, not HttpWebRequest constructor; concrete run-time type will be figured out of URL schema (https:// in your case).

See:
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.webrequest.aspx[^] (see code sample for HTTP, but use "https://...").

I don''t know detail of your authentication page, but if this is a regular Web form with user name/password, you can log in using "POST" method.
This can give you the idea:
