This is the way I do it. Every time the user navigates around the site (clicks a link) I log the time against there login record and at the same time check the last time all the other users last clicked a link if it was longer than a set time I set there login to false forcing the logon page if they do try and navigate again.

You never know when user closes his/her IE (or whatever browser). You just CAN NOT know it. All you can do is write a custom javascript function for onUnload event of the page. (C# doesn't help you here). Here you could load a page that informs you that user closed his browser. Still you don't know if he switched the power off his computer.
