PowerShell显示耗时

Question

我有一个脚本，它启动一个事件并等待用户按任意键来停止脚本执行。我试图找到一种方法来显示计时器(脚本运行了多长时间)，同时等待用户输入 Read-Host 。有办法实现吗？

<小时/>

这有效

$Time = [System.Diagnostics.Stopwatch]::StartNew()
while ($true) {
    $CurrentTime = $Time.Elapsed
    write-host $([string]::Format("`rTime: {0:d2}:{1:d2}:{2:d2}",
                                  $CurrentTime.hours,
                                  $CurrentTime.minutes,
                                  $CurrentTime.seconds)) -nonewline
    sleep 1
    if ($Host.UI.RawUI.KeyAvailable -and ("q" -eq $Host.UI.RawUI.ReadKey("IncludeKeyUp,NoEcho").Character)) {
        Write-Host "Exiting now"
        break;
    }
}

这给了我我想要的输出:)

$StartTime = $(get-date)

$elapsedTime = $(get-date) - $StartTime

$totalTime = "{0:HH:mm:ss}" -f ([datetime]$elapsedTime.Ticks)
