[Solved] Find number of Logged in Users in ASP.Net website

Hi,

You can use Windows Performance counters for this (perfmon)

ASP.NET Applications > Sessions Active counter.

You can access these performance counters using the System.Diagnostics namespace.

In below code instead of MYSERVERHOSTNAME.domain pass your Serverhostname(i.e. MachineName)

C#

PerformanceCounter pc = new PerformanceCounter("ASP.NET Applications","Sessions Active", "__Total__", "MYSERVERHOSTNAME.domain");
while (true)
{
    Console.WriteLine(pc.NextValue());
    System.Threading.Thread.Sleep(1000);
}

Refer below link for more info

if the counter seems too high: http://support.microsoft.com/kb/969722

Also you can use Application State.(In Global.asax)

Handle the Application.Start event adding the following:

Application["LiveSessionsCount"] = 0;

Handle the Session.Start event adding the following:

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

Handle the Session.End event adding the following:

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

To retrieve sessions count inside your page write the following:

nt LiveSessionsCount = (int) Application["LiveSessionsCount"];

I hope this will help you out.
