SystemEvents.SessionEnding not firing

Question

I am developing an windows forms application in c# .net 4.0. I want to capture windows logoff event.

Here is the code:

    public Form1()
    {
              


        

Answer 1

This could be useful to someone.

if form close event is included

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        e.Cancel = true;
    }

then SessionEnding will not be fired, i just encoutered this problem and rectified it

void SystemEvents_SessionEnding(object sender, Microsoft.Win32.SessionEndingEventArgs e)
    {}

here i need to prevent Form close upon Alt+F4 command, so i added this form closing event this resulted in this issue. so we can integrate session ending event in form close event. Option 2 in Refered from stackoverflow answer
