.net 从 PowerShell 挂起或休眠

Suspend or hibernate from PowerShell

提问by Trevor Sullivan

I am interested in using Windows PowerShell to suspend or hibernate a computer. How do you achieve this?

我对使用 Windows PowerShell 挂起或休眠计算机很感兴趣。你如何做到这一点？

I am already aware of the Stop-Computerand Restart-Computercmdlets, which are included out of the box, but these do not achieve the functionality that I am after.

我已经知道Stop-Computer和Restart-Computercmdlet，它们是开箱即用的，但是它们没有实现我所追求的功能。

You can use the SetSuspendStatemethod on the System.Windows.Forms.Applicationclass to achieve this. The SetSuspendStatemethod is a static method.

您可以使用类SetSuspendState上的方法System.Windows.Forms.Application来实现这一点。该SetSuspendState方法是静态方法。

[MSDN] SetSuspendState

[MSDN] 设置暂停状态

There are three parameters:

共有三个参数：

• State [System.Windows.Forms.PowerState]
• Force [bool]
• disableWakeEvent [bool]

• 状态 [System.Windows.Forms.PowerState]
• 力量 [bool]
• 禁用唤醒事件 [bool]

To call the SetSuspendStatemethod:

要调用该SetSuspendState方法：

# 1. Define the power state you wish to set, from the
#    System.Windows.Forms.PowerState enumeration.
$PowerState = [System.Windows.Forms.PowerState]::Suspend;

# 2. Choose whether or not to force the power state
$Force = $false;

# 3. Choose whether or not to disable wake capabilities
$DisableWake = $false;

# Set the power state
[System.Windows.Forms.Application]::SetSuspendState($PowerState, $Force, $DisableWake);

Putting this into a more complete function might look something like this:

把它放到一个更完整的函数中可能看起来像这样：

function Set-PowerState {
    [CmdletBinding()]
    param (
          [System.Windows.Forms.PowerState] $PowerState = [System.Windows.Forms.PowerState]::Suspend
        , [switch] $DisableWake
        , [switch] $Force
    )

    begin {
        Write-Verbose -Message 'Executing Begin block';

        if (!$DisableWake) { $DisableWake = $false; };
        if (!$Force) { $Force = $false; };

        Write-Verbose -Message ('Force is: {0}' -f $Force);
        Write-Verbose -Message ('DisableWake is: {0}' -f $DisableWake);
    }

    process {
        Write-Verbose -Message 'Executing Process block';
        try {
            $Result = [System.Windows.Forms.Application]::SetSuspendState($PowerState, $Force, $DisableWake);
        }
        catch {
            Write-Error -Exception $_;
        }
    }

    end {
        Write-Verbose -Message 'Executing End block';
    }
}

# Call the function
Set-PowerState -PowerState Hibernate -DisableWake -Force;

Note: In my testing, the -DisableWakeoption did not make any distinguishable difference that I am aware of. I was still capable of using the keyboard and mouse to wake the computer, even when this parameter was set to $true.

注意：在我的测试中，该-DisableWake选项没有产生我所知道的任何可区分的差异。我仍然能够使用键盘和鼠标来唤醒计算机，即使将此参数设置为$true.

Shutdown %windir%\System32\shutdown.exe -s

关掉 %windir%\System32\shutdown.exe -s

Reboot %windir%\System32\shutdown.exe -r

重启 %windir%\System32\shutdown.exe -r

Logoff %windir%\System32\shutdown.exe -l

注销 %windir%\System32\shutdown.exe -l

Standby %windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Standby

支持 %windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Standby

Hibernate %windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Hibernate

休眠 %windir%\System32\rundll32.exe powrprof.dll,SetSuspendState Hibernate

EDIT: As pointed out in comment by @mica, the suspend (sleep) actually hibernates. Apparently this happens in windows 8 and above. To 'sleep', disable hibernation OR get an external Microsoft tool (not built-in) "One of Microsoft's Sysinternals tool is PsShutdown using the command psshutdown -d -t 0it will correctly sleep, not hibernate, a computer" Source: https://superuser.com/questions/42124/how-can-i-put-the-computer-to-sleep-from-command-prompt-run-menu

编辑：正如@mica 在评论中指出的那样，挂起（睡眠）实际上是在休眠。显然，这发生在 Windows 8 及更高版本中。要“睡眠”，请禁用休眠或获取外部 Microsoft 工具（非内置）“Microsoft 的 Sysinternals 工具之一是 PsShutdown，使用psshutdown -d -t 0它可以正确睡眠而不是休眠计算机的命令”来源：https: //superuser.com /questions/42124/how-can-i-put-the-computer-to-sleep-from-command-prompt-run-menu

I use the shutdown executable in C:\Windows\System32

我使用 C:\Windows\System32 中的关机可执行文件

shutdown.exe /h

I tried reducing this down to a one-liner but was getting an error. Here's my solution:

我尝试将其减少为单行，但出现错误。这是我的解决方案：

[Void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") 
[System.Windows.Forms.Application]::SetSuspendState("Hibernate", $false, $false);
