推荐答案

让我们假设您拥有一个站点，该站点的母版页包含一些简单页面，并且用户拥有在登录过程中，请为会话分配一些内容，例如

Let''s assume you have a site with a master page that has a few simple pages and that the user has logged in. As part of the login process assign something to the Session, perhaps like

Session.Add(Key, Value);

.然后，例如，当用户每次导航到另一个页面或启动PostBack事件时，您都可以测试此值.

您可以这样做:

. You can then test for this value each time the user, for instance, navigates to another page or initiates a PostBack event.

You could do:

// Pseudo code.
if (Session[Key] == null)
{
    // Do something: user no longer valid.
}

如果Session过期，则Session变量将为null，您可以测试该变量并采取适当的措施.

If the Session has expired the Session variable will be null which you can test for and take the appropriate action.

将此代码写入web.config文件中的

write this code in web.config file under

<system.web>

<sessionstate timeout="15"></sessionstate>

默认情况下为20分钟.当用户在15分钟后会执行某项操作时.然后页面将重新加载并重定向到登录页面.

希望对您有帮助...
