I am not sure about the nature of your problem, as you provided too few details, however,
you stated that you want to destroy the session, in which case I would suggest that you use

C#

Session.Abandon();

Note: When this method is called, the current Session object is not deleted until all of the script on the current page have been processed. This means that it is possible to access session variables on the same page as the call to Abandon, but not from another Web page.

Cheers,
Edo

example: a session variable
Session["gainMark"] = 0;

Solution 2

Try using Session.Clear() or Session.Abandon(); The difference between the two is

Clear removes all keys and values from the session-state collection.

Abandon removes all the objects stored in a Session. If you do not call the Abandon method explicitly, the server removes these objects and destroys the session when the session times out.
It also raises events like Session_End.

Regards..:)

Solution 10

C#

If you want to remove a specific item from the session use:

Session.Remove("YourItem");
 or else you can use
Session.Abandon()
