How to Kill A Session or Session ID (ASP.NET/C#)

Question

How can I destroy a session (Session["Name"]) when the user clicks the logout button?

I'm looking through the ASP.NET API Reference on MSDN and it doesn't seem to have much information. It seems rather limited. But I cannot find any other pages for ASP.NET Classes etc.

I have tried:

Session.Abandon(); and Session.Contents.Remove("Name"); neither of them work. ( I found these in a forum from a Google search)

Answer 1

Session.Abandon() this will destroy the data.

Note, this won't necessarily truly remove the session token from a user, and that same session token at a later point might get picked up and created as a new session with the same id because it's deemed to be fair game to be used.

Answer 2

Session.Abandon()

This marks the session as Abandoned, but the session won't actually be Abandoned at that moment, the request has to complete first.

Answer 3

You kill a session like this:

Session.Abandon()

If, however, you just want to empty the session, use:

Session.Clear()
