Event to detect System wake up from sleep in C#

Question

I need to detect the system power state mode. To be precise, I need an event which fires up when windows 7 wakes up from sleep. I am already using:

SystemEvents.PowerModeChanged += SystemEvents_PowerModeChanged; 

But the problem with this event is that it is raised up four times: possibly when computer goes into sleep mode and after computer wakes up. I want an event which is raised at computer wake up only. Is there any event for this?

Answer 1

SystemEvents.PowerModeChanged += OnPowerChange;  private void OnPowerChange(object s, PowerModeChangedEventArgs e)  {     switch ( e.Mode )      {         case PowerModes.Resume:          break;         case PowerModes.Suspend:         break;     } }
