从 PowerShell 挂起或休眠

我有兴趣使用 Windows PowerShell 挂起或休眠计算机。你如何实现这一目标？

我已经知道Stop-Computer and Restart-Computercmdlet，它们是开箱即用的，但它们并没有实现我想要的功能。

您可以使用SetSuspendState方法上的System.Windows.Forms.Application类来实现这一点。这SetSuspendState方法是静态方法。

[MSDN] 设置挂起状态 http://msdn.microsoft.com/en-us/library/system.windows.forms.application.setsuspendstate%28v=vs.110%29.aspx

有三个参数：

• State [System.Windows.Forms.PowerState]
• Force [bool]
• 禁用唤醒事件[bool]

要致电SetSuspendState method:

# 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);

将其放入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;

注意：在我的测试中，-DisableWake据我所知，选项没有产生任何明显的差异。即使此参数设置为，我仍然能够使用键盘和鼠标唤醒计算机$true.
