防止 Windows 11 休眠

Question

我正在努力阻止 Windows 11 休眠。

我尝试了以下的每一种组合：

ES_CONTINUOUS | ES_SYSTEM_REQUIRED | ES_AWAYMODE_REQUIRED

for (;;)
{
    SetThreadExecutionState(ES_SYSTEM_REQUIRED);
    // SetThreadExecutionState(ES_SYSTEM_REQUIRED | ES_CONTINUOUS);
    // SetThreadExecutionState(ES_AWAYMODE_REQUIRED)
    // SetThreadExecutionState(ES_AWAYMODE_REQUIRED | ES_CONTINUOUS);
    // SetThreadExecutionState(ES_AWAYMODE_REQUIRED | ES_SYSTEM_REQUIRED | ES_CONTINUOUS);

    Thread.Sleep(10000);
    Console.WriteLine("The current time is: " + DateTime.Now);             
}

private const uint ES_CONTINUOUS = 0x80000000;
private const uint ES_SYSTEM_REQUIRED = 0x00000001;
private const uint ES_DISPLAY_REQUIRED = 0x00000002;
private const uint ES_AWAYMODE_REQUIRED = 0x00000040;

我已经在for循环内部和for循环外部尝试过。

我所做的任何事情都无法阻止系统在大约 3 - 5 分钟后进入睡眠状态。

在 Windows 11 中是否有不同的方法来执行此操作？

using System;
using System.Runtime.InteropServices;

public class PreventSleep
{
    // ES_AWAYMODE_REQUIRED is a flag that specifies to the system that Away Mode should be enabled, 
    //  keeping the system running even when it would otherwise enter a low-power state.
    private const uint ES_AWAYMODE_REQUIRED = 0x00000040;

    // The ES_CONTINUOUS flag indicates that the operating system should consider the thread's activity 
    //  as user-initiated, meaning it should not enter sleep mode while the thread is active. 
    private const uint ES_CONTINUOUS = 0x80000000;

    // ES_DISPLAY_REQUIRED is a flag that specifies to the system that the display should 
    //  remain on and not enter sleep mode due to inactivity.
    private const uint ES_DISPLAY_REQUIRED = 0x00000002;

    // The ES_SYSTEM_REQUIRED flag specifies that the system should not enter sleep mode.
    private const uint ES_SYSTEM_REQUIRED = 0x00000001;

    // ES_USER_PRESENT is a flag that specifies to the system that a user is present and interacting 
    //  with the system, preventing the system from entering sleep or idle states.
    private const uint ES_USER_PRESENT = 0x00000004;

    // The SetThreadExecutionState function is imported using DllImport from kernel32.dll. 
    //  This allows your C# code to call this native Windows API function.
    [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern uint SetThreadExecutionState(uint esFlags);

    public static void PreventSleepMode()
    {
        SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED);
    }

    public static void AllowSleepMode()
    {
        SetThreadExecutionState(ES_CONTINUOUS);
    }
}


How to use it?

// Prevent Sleep
PreventSleep.PreventSleepMode();

// Allow Sleep
PreventSleep.AllowSleepMode();
