Method 1

You can’t destroy all the sessions, you can only clear current session. You probably have to recycle the application pool to clear out all sessions.

Use HttpSessionState.Clear to clear out current session

From MSDN – HttpSessionState.Clear Method

Removes all keys and values from the session-state collection.

Call it like :

Session.Clear();

Method 2

I want destroy all sessions at one time

I’m fairly sure you can’t do this, short of recycling the application.

The currently accepted answer suggests using Session.Clear, but this only clears the current session – it is the same as Session.RemoveAll.

Why are there two methods Clear and RemoveAll that do exactly the same thing? I suspect RemoveAll is provided for backwards compatibility with the ASP Classic Session object, while Clear is the more usual method name for clearing items from a .NET Collection.

Method 3

There are three methods that can remove session
variables

Session.Clear()
Session.RemoveAll()
Session.Abandon()

Clear() and RemoveAll() perform the same thing: remove the session variables
but keep the current session in memory. Whereas, Abandon() ends the current
session.

Method 4

try:

Session.Contents.RemoveAll()

Method 5

Use Session.Clear() or Session.RemoveAll() Method

Session.Clear()
    or
 Session.RemoveAll()

Method 6

You have to use

this.Page.Session.Clear();

Abandon is for the current session only.
