计算机状态（睡眠，休眠，锁定等）Windows 10

Question

I need to check the current state of the Computer. Hibernate, Sleep, onStand-by Locked, etc

I Just want to Ask on how to get the current status of my computer using C#? I have already get when the computer is locked by detecting the LockApp process but I can't get if it is on sleep mode, or hibernate.

I want to try a project that will run using the task scheduler and check the current state of the computer and will show on the console.

Please note that I is to detect the state of the computer when my project runs. Thank you. And sorry for my bad English. :)

//Will return true if the Computer is Locked
public bool Lock()
{
    Boolean locked = false;
    Process[] LockApp = Process.GetProcesses();
    foreach (Process theprocess in LockApp)
    {
        if (theprocess.ProcessName == "LockApp")
        {
            locked = true;
            Console.WriteLine("LockApp: " + locked.ToString());
        }
    }
    return locked;
}
//Will return true if still on Startuptime (+5min)
public bool onStartupTime()
{
    bool oST = false;
    DateTime ST = DateTime.Now.AddMilliseconds(- 
    Environment.TickCount);
    DateTime Less = DateTime.Now.AddMinutes(-5);
    DateTime Now = DateTime.Now;

    Console.WriteLine(ST.ToString("yyyy-MM-dd HH:mm:ss"));
    Console.WriteLine(Less.ToString("yyyy-MM-dd HH:mm:ss"));
    Console.WriteLine(Now.ToString("yyyy-MM-dd HH:mm:ss"));

    if (ST >= Less)
    {
        oST = true;
    }

    return oST;
}

OnStartup(-5mins): true or false Lock: true or false Sleep: true or false hibernate: true or false

According to this link , you can do it using SystemEvents.PowerModeChanged . An example of using is also posted there:

    SystemEvents.PowerModeChanged += new PowerModeChangedEventHandler(OnPowerModeChanged);


    private static void OnPowerModeChanged(object sender, PowerModeChangedEventArgs e)
    {
        switch (e.Mode)
        {
            case PowerModes.Resume:
                MessageBox.Show("PowerMode: OS is resuming from suspended state");
                break;

            case PowerModes.Suspend:
                MessageBox.Show("PowerMode: OS is about to be suspended");
                break;
        }
    }
