How to tell if a PC is rebooting

Question

I have a c# app the kicks off some other processes and those processes can kick off a reboot. Problem is the reboot is greatly delayed because the first c# app is still running. It will forcibly get rebooted eventually but it delays things by about 5-8min. So I need to put in some kind of check/hook in the c# app to see if the PC is starting a reboot process. Any ideas?

If it's a Windows Forms or WPF application I'd check out the Microsoft.Win32.SystemEvents.SessionEnding event: http://msdn.microsoft.com/en-us/library/microsoft.win32.systemevents.sessionending.aspx Curiously the example in that link is for trapping the WM_QUERYENDSESSION message which may be a better option in any case: http://msdn.microsoft.com/en-us/library/windows/desktop/aa376890(v=vs.85).aspx
