C# wrapper for win32's System Power Status

Examples

Get a snapshot of the current power status

var statusProvider = new PowerStatusProvider();
var status = statusProvider.GetStatus();
Console.WriteLine($"{status}");

PowerStatus { AcLineStatus = Offline, BatteryFlags = 0, BatteryLifeProportion = 0.47, BatterySaver = False, BatteryTime = 01:53:54, FullTime =  }

Receive notifications when something changes

var statusProvider = new PowerStatusProvider();
using (statusProvider.Subscribe(
    e => Console.WriteLine(e.ToString()),
    PowerStatusNotification.BatteryProportionChanged(proportion =>
        Console.WriteLine($"The battery proportion is {proportion}")),
    PowerStatusNotification.BatterySaverIsOn(isOn =>
        Console.WriteLine($"Battery saver {(isOn ? "is" : "is not")} on")),
    PowerStatusNotification.CurrentMonitorDisplayState(state =>
        Console.WriteLine($"The current monitor's display state is {state}")),
    PowerStatusNotification.LidIsOpen(isOpen =>
        Console.WriteLine($"The lid {(isOpen ? "is" : "is not")} open")),
    PowerStatusNotification.PowerSchemePersonalityChanged(personality =>
        Console.WriteLine($"The power scheme is {personality}")),
    PowerStatusNotification.PowerSource(powerSource =>
        Console.WriteLine($"The power source is {powerSource}")),
    PowerStatusNotification.PrimaryMonitorIsOn(isOn =>
        Console.WriteLine($"The primary monitor {(isOn ? "is" : "is not")} on")),
    PowerStatusNotification.SessionDisplayState(state =>
        Console.WriteLine($"The session display is {state}")),
    PowerStatusNotification.SystemAwayModeChanged(awayMode =>
        Console.WriteLine($"The system is {awayMode} away mode")),
    PowerStatusNotification.SystemIsBusy(() =>
        Console.WriteLine("The system is busy")),
    PowerStatusNotification.UserIsActive(isActive =>
        Console.WriteLine($"The user {(isActive ? "is" : "is not")} active"))
))
{
    Console.WriteLine("Press any key to stop listening to events...");
    Console.ReadKey(true);
}

Press any key to stop listening to events...
