EDIT AFTER ANSWERS: 我在Global.asax中的Application_Start如下:
protected void Application_Start(object sender, EventArgs e)
{
Application["OnlineUsers"] = 0;
OnlineUsers.Update_SessionEnd_And_Online(
DateTime.Now,
false);
AddTask("DoStuff", 10);
}
被调用的存储过程是:
ALTER Procedure [dbo].[sp_OnlineUsers_Update_SessionEnd_And_Online]
@Session_End datetime,
@Online bit
As
Begin
Update OnlineUsers
SET
[Session_End] = @Session_End,
[Online] = @Online
End
我有两种获取在线用户的方法:
- 使用
Application["OnlineUsers"] = 0;
- 另一种方法是使用数据库
所以,对于第二种方法,我在 Application_Start
中重置了所有在线用户。该表中有超过482,751条记录。
