推荐答案

处理主窗体 FormClosing事件 [ ^ ]并自动退出。



你可能值得暂停登录，因此它们仅适用于af inite期间，或发出会话ID，以便您可以判断会话何时达到异常终止并且登录shoudl已失效。

Handle the main form FormClosing event[^] and auto log out there.

It may be worth your putting a timeout on logins, so they are only valid for a finite period, or issuing them with a session ID so that you can tell when a session reached an abnormal termination and the login shoudl have been invalidated.

如果Web应用程序

使用会话。在全局文件[Application_End]上将其设置为null。如果session为null，请确保将它们重定向到loggin页面。

If web application
Use sessions. Set it to null on Global file [Application_End]. Make sure that they are redirected to loggin page if session is null.

当您使用tabbed-browser时会发生这种情况。在选项卡式浏览器中，但默认情况下会话共享，关闭一个选项卡不会清除会话。它更多的是与应用程序设置相关的浏览器设置。

This would have happened when you had used tabbed-browser. In tabbed browser, but default the session is shared across and closing one tab does not clear the session. It is more of the browser setting related than application setting.
