Question

我想查询机器的正常运行时间，并决定通过PowerShell尝试这个，但我很难让它运行起来。这是我到目前为止所做的：

   function Get-PCUptime {

        param (
            [Parameter(ValueFromPipeline=$true)]
            [String]$computer  = (Read-Host "Enter a computer name")
        )


        $lastboottime = (Get-WmiObject -Class Win32_OperatingSystem -Credential Administrator -comp $computer)
        $sysuptime = (Get-Date) – [System.Management.ManagementDateTimeconverter]::ToDateTime($lastboottime.LastBootUpTime)

        if ($lastboottime -ne $NULL){
            Write-Host “System($computer) is Uptime since : ” $sysuptime.days “days” $sysuptime.hours `
            “hours” $sysuptime.minutes “minutes” $sysuptime.seconds “seconds” -Foregroundcolor Gray;
        } 
    }

我似乎无法使其正常工作，因为我想将其转换为天，小时，分钟等。

这是我收到的错误：

异常调用＆＃34; ToDateTime＆＃34;用＆＃34; 1＆＃34;参数：＆＃34;指定的参数超出了有效值的范围。参数名称：dmtfDate＆＃34;

您可以在ConvertToDateTime

上使用Win32_OperatingSystem方法

function Get-PCUptime {
    param (
        [Parameter(ValueFromPipeline=$true,
                   HelpMessage="Enter a Computer Name"
        )]
        [String]$computer
    )

    $OS = (Get-WmiObject -Class Win32_OperatingSystem -Credential Administrator -comp $computer)
    $sysuptime = (Get-Date) – ($OS.ConvertToDateTime($OS.LastBootUpTime))

    if ($OS -ne $NULL){
        Write-Host “System($computer) is Uptime since : ” $sysuptime.days “days” $sysuptime.hours `
        “hours” $sysuptime.minutes “minutes” $sysuptime.seconds “seconds” -Foregroundcolor Gray;
    } 
}

想用PowerShell查询远程PC的正常运行时间
