How to count the number of online members on a website and display as done in this site?

Hi Kavita,

You can do this by writing code in global.asax

In Application_Start event add this line like that

void Application_Start(object sender, EventArgs e)

   Application["OnlineUsers"] = 0;

And in Session_Start event add these lines like that

void Session_Start(object sender, EventArgs e)

    Application.Lock();

    Application["OnlineUsers"] = (int)Application["OnlineUsers"] + 1;

    Application.UnLock();

And in Session_End event add these lines like that
 void Session_End(object sender, EventArgs e)

    Application.Lock();

    Application["OnlineUsers"] = (int)Application["OnlineUsers"] - 1;

    Application.UnLock();

In order for this to work correctly we need to enable sessionstate and configure its mode to InProc value (in our web.config file):

<system.web>

    <sessionState mode="InProc" timeout="20" />

system.web>

And to show Total Online User in aspx page write this

Online Users: <%= Application["OnlineUsers"].ToString() %>
