Powershell如何实现工作线程

问题描述：

我的脚本中有一个性能问题，因此我想实现某种工作人员主题.但是到目前为止，我还没有找到解决方案.

I have a little performance issue in my script, so i would like to implement some sort of worker theads. but so far i have not been able to find a solution..

我希望的是这样的:

启动工作线程池-这些线程从队列中获取命令"并对其进行处理
主脚本在运行时会将命令"写入队列
一旦完成，主程序就会告诉每个线程停止
main将在退出之前等待所有工作人员结束.

有人知道如何做到这一点吗?

does anybody have en idea on how to do this?

答

在基思·希尔(Keith Hill)的指针的帮助下-我使它工作了-非常感谢...

With some help from the pointers made by Keith hill - i got it working - thanks a bunch...

这是我的概念证明的代码片段:

Here is a snipping of the code that did my prove of concept:

function New-Task([int]$Index,[scriptblock]$ScriptBlock) {
    $ps = [Management.Automation.PowerShell]::Create()
    $res = New-Object PSObject -Property @{
        Index = $Index
        Powershell = $ps
        StartTime = Get-Date
        Busy = $true
        Data = $null
        async = $null
    }

    [Void] $ps.AddScript($ScriptBlock)
    [Void] $ps.AddParameter("TaskInfo",$Res)
    $res.async = $ps.BeginInvoke()
    $res
}

$ScriptBlock = {
    param([Object]$TaskInfo) 
    $TaskInfo.Busy = $false
    Start-Sleep -Seconds 1
    $TaskInfo.Data = "test $($TaskInfo.Data)"
}

$a = New-Task -Index 1 -ScriptBlock $ScriptBlock 
$a.Data = "i was here"
Start-Sleep -Seconds 5
$a

这是证明数据已传递到线程中并再次返回的结果:

And here is the result proving that the data was communicated into the thread and back again:

Data       : test i was here
Busy       : False
Powershell : System.Management.Automation.PowerShell
Index      : 1
StartTime  : 11/25/2013 7:37:07 AM
async      : System.Management.Automation.PowerShellAsyncResult

如您所见，$ a.data现在前面有"test"

as you can see the $a.data now have "test" in front

非常感谢...
