推荐答案

在 Global.asax 文件中编写与整个应用程序交互的代码.
示例代码如下:

Write code in Global.asax file which interacts with the entire application.
The sample code is given below:

void Application_OnStart(Object Sender, EventArgs E)
{
     Application["CurrentUsers"] = 0;
}
void Session_OnStart(object Sender, EventArgs E)
{
     Application.Lock();
     Application["CurrentUsers"] = System.Convert.ToInt32(Application["CurrentUsers"]) + 1;
     Application.UnLock();
}
void Session_OnEnd(object Sender, EventArgs E)
{
     Application.Lock();
     Application["CurrentUsers"] = System.Convert.ToInt32(Application["CurrentUsers"]) - 1;
     Application.UnLock();
}

如果您正在进行会话，那么您知道有人在线.您必须等待一段时间才能假定它们不是.然后，您可以算出他们的数量

If you have a session, then you know someone is online. You have to wait for a time out to assume they are not. You can then count them
