.net - 从PowerShell挂起或休眠

我对使用Windows PowerShell挂起或休眠计算机感兴趣。您如何实现的？

我已经知道Stop-Computer和Restart-Computer cmdlet都是现成的，但是它们并没有实现我所追求的功能。

最佳答案

您可以在SetSuspendState类上使用System.Windows.Forms.Application方法来实现此目的。 SetSuspendState方法是静态方法。

[MSDN] SetSuspendState

有三个参数:

状态[System.Windows.Forms.PowerState]

强制[bool]

disableWakeEvent [bool]

调用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);

将其放入更完整的功能可能类似于以下内容:

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选项没有任何我知道的明显区别。即使将此参数设置为$true，我仍然能够使用键盘和鼠标唤醒计算机。
