Assembly: System (in system.dll)
A SessionEnding event is raised when the user is trying to log off or shut the system down.
This SessionEnding event can sometimes be canceled. Setting the Cancel property of a SessionEndingEventArgs to false will request that the session continue instead of ending. Making such a request provides no guarantee that the session will not end.
