Add every user in a session transaction.

public List<Users> ListUsers

{

get { return (List<Users>)SesionTransaccion["Users"]; }

set { SesionTransaccion["Users"] = value; }

}

after adding them you can get all the users from the collection.

it will work.

Got what you needed. Please mark as answer.

If you are using the default membership provider, you can just use:

Membership.GetNumberOfUsersOnline()

I am assuming you are using the the built-in membership features of ASP.NET (using the login controls, etc.). Otherwise you would have had to write your own code to manage membership (ie, a custom membership provider).

Are you using the built-in features? If so, Membership.GetNumberOfUsersOnline should work.

Since you did everything else yourself, I think you are stuck tracking the users yourself. I suppose you could create an application object (Application("whatever")) and add and subtract one as you authenticate or sign out users, or you could just add another field to your database to indicate if the user is logged in and query the database. Something like...

SELECT * FROM whatever WHERE LoggedIn = 1
RETURN @@ROWCOUNT

Cannot detect the browser close but you can update the state in Session_End event,
