I want me program to write to the console when the computer it going to sleep but am unable to do so. I think I am setting this up wrong. Here is what I have...

Edit: New .cs file

using LightFX;
using System;
using System.Threading;
using System.Text;
using Microsoft.Win32;
using ConsoleApplication3;

namespace SampleApp5
{
    class Program
    {
        static void Main()
        {
           
        }

        SystemEvents.PowerModeChanged += PowerModeChanged;
    }
    class PowerModeChanged
    {

    }
}

You have mabye found what you looking for, but still.. This code works for me:

using System;
using Microsoft.Win32;


class Powerstatus
{
static void Main(string[] args)
{
    SystemEvents.PowerModeChanged +=
        new PowerModeChangedEventHandler(SystemEvents_PowerModeChanged);
    Console.ReadLine();
}

static void SystemEvents_PowerModeChanged(object sender, PowerModeChangedEventArgs e)
{
    Console.WriteLine(e.Mode);
}

}

That event is raised by the SystemEvents class (it's a static event). You just need to bind to it:

SystemEvents.PowerModeChanged += OnPowerModeChanged;

You need to do this somewhere in your main method.

And, of course, delete your custom delegate, since it's already defined by the framework. You don't need this line:

public static event PowerModeChangedEventHandler PowerModeChanged;

UPDATE:

    static void Main()
    {
       SystemEvents.PowerModeChanged += OnPowerModeChanged;
       Console.ReadLine(); //just wait, don't exit immediately.
    }

    private static void OnPowerModeChanged(object sender, PowerModeChangedEventArgs e) 
    {
        //Handle the event here.
    }
