推荐答案

您可以将会话信息存储在数据库中.存储后，您可以获得登录的用户数.但是问题将出在会话过期上.如果您关闭会话，则会话不会过期.如果您关闭浏览器，则用户将看起来像在线.

检查本文:在SQL Server中存储会话 [

Hi,

You can store your session information in database. After storing you can get the number of users that are login. But the problem will be with session expiration. if your session will not expire if you close your brower user will be look like online.

Check this article : Store Session in SQL Server[^]

Other way is you can set a flag in userMaster table and once user logout you can reset it. this way you can also get the online user. But again in this scenario you have such issue with closing/browser crash.

进入一个具有这样的事件的Globle.asax页面；

Take One Globle.asax page this having events Like This;

void Application_Start(object sender, EventArgs e)
        {
            Application["Toatal"] = 0;
            Application["Online"] = 0;
            Session.Timeout = 60;

        }

        void Application_End(object sender, EventArgs e)
        {
            //  Code that runs on application shutdown

        }

        void Application_Error(object sender, EventArgs e)
        {
            // Code that runs when an unhandled error occurs

        }

        void Session_Start(object sender, EventArgs e)
        {
            Application["Toatal"] = Convert.ToInt32(Application["Toatal"]) + 1;
            Application["Online"] = Convert.ToInt32(Application["Online"]) + 1;

        }

        void Session_End(object sender, EventArgs e)
        {
            Application["Online"] = Convert.ToInt32(Application["Online"]) - 1;

        }

接受另一个Aspx页面，其中包含两个标签

并分配这两个值

Take another Aspx page In that take two lables

and assign this two vales

Application["Toatal"] and
            Application["Online"]
