使用秒表和格式化经过的时间:

Function FormatElapsedTime($ts) 
{
    $elapsedTime = ""

    if ( $ts.Minutes -gt 0 )
    {
        $elapsedTime = [string]::Format( "{0:00} min. {1:00}.{2:00} sec.", $ts.Minutes, $ts.Seconds, $ts.Milliseconds / 10 );
    }
    else
    {
        $elapsedTime = [string]::Format( "{0:00}.{1:00} sec.", $ts.Seconds, $ts.Milliseconds / 10 );
    }

    if ($ts.Hours -eq 0 -and $ts.Minutes -eq 0 -and $ts.Seconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0:00} ms.", $ts.Milliseconds);
    }

    if ($ts.Milliseconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0} ms", $ts.TotalMilliseconds);
    }

    return $elapsedTime
}

Function StepTimeBlock($step, $block) 
{
    Write-Host "`r`n*****"
    Write-Host $step
    Write-Host "`r`n*****"

    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $time = $sw.Elapsed

    $formatTime = FormatElapsedTime $time
    Write-Host "`r`n`t=====> $step took $formatTime"
}

使用样本

StepTimeBlock ("Publish {0} Reports" -f $Script:ArrayReportsList.Count)  { 
    $Script:ArrayReportsList | % { Publish-Report $WebServiceSSRSRDL $_ $CarpetaReports $CarpetaDataSources $Script:datasourceReport };
}

StepTimeBlock ("My Process")  {  .\do_something.ps1 }

使用Measure-Command

例子

Measure-Command { <your command here> | Out-Host }

到Out-Host的管道允许您查看命令的输出，即 否则由测量命令消耗。

使用秒表和格式化经过的时间:

Function FormatElapsedTime($ts) 
{
    $elapsedTime = ""

    if ( $ts.Minutes -gt 0 )
    {
        $elapsedTime = [string]::Format( "{0:00} min. {1:00}.{2:00} sec.", $ts.Minutes, $ts.Seconds, $ts.Milliseconds / 10 );
    }
    else
    {
        $elapsedTime = [string]::Format( "{0:00}.{1:00} sec.", $ts.Seconds, $ts.Milliseconds / 10 );
    }

    if ($ts.Hours -eq 0 -and $ts.Minutes -eq 0 -and $ts.Seconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0:00} ms.", $ts.Milliseconds);
    }

    if ($ts.Milliseconds -eq 0)
    {
        $elapsedTime = [string]::Format("{0} ms", $ts.TotalMilliseconds);
    }

    return $elapsedTime
}

Function StepTimeBlock($step, $block) 
{
    Write-Host "`r`n*****"
    Write-Host $step
    Write-Host "`r`n*****"

    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $time = $sw.Elapsed

    $formatTime = FormatElapsedTime $time
    Write-Host "`r`n`t=====> $step took $formatTime"
}

使用样本

StepTimeBlock ("Publish {0} Reports" -f $Script:ArrayReportsList.Count)  { 
    $Script:ArrayReportsList | % { Publish-Report $WebServiceSSRSRDL $_ $CarpetaReports $CarpetaDataSources $Script:datasourceReport };
}

StepTimeBlock ("My Process")  {  .\do_something.ps1 }

简单的

function time($block) {
    $sw = [Diagnostics.Stopwatch]::StartNew()
    &$block
    $sw.Stop()
    $sw.Elapsed
}

然后可以用as

time { .\some_command }

您可能需要调整输出

您还可以从历史记录中获取最后一个命令，并从它的StartExecutionTime中减去它的EndExecutionTime。

.\do_something.ps1  
$command = Get-History -Count 1  
$command.EndExecutionTime - $command.StartExecutionTime

一种更受PowerShell启发的方式来访问您关心的属性值:

$myCommand = .\do_something.ps1
Measure-Command { Invoke-Expression $myCommand } | Select -ExpandProperty Milliseconds

    4

As Measure-Command返回一个TimeSpan对象。

注意:TimeSpan对象也有TotalMilliseconds作为双变量(如上面我的例子中的4.7322 TotalMilliseconds)，这可能对您有用。就像TotalSeconds, TotalDays等。
