powershell - 将 "native"对象传递给后台作业

Question

这是我想以一种或另一种方式实现的目标。

我有一个定义一些对象的自定义程序集。在脚本中，我创建了一个自定义对象，该对象将传递给脚本块，并保持该对象的行为。

Add-Type -AssemblyName MyCustomDLL

$global:object = new-object MyCustomDLL.MyCustomObject()
$object | gm

$jobWork = { param ($object) $object | gm } # I'd like to keep my object behavior in that block

$job = Start-Job -ScriptBlock $jobWork -ArgumentList $object
Wait-Job $job
Receive-Job $job

我该怎么做或达到相同的效果？谢谢你的帮助

代替后台作业，您可以将PowerShell与BeginInvoke和EndInvoke结合使用。这是在“作业”中传递事件对象，然后在其中进行更改并获得结果的简单但可行的示例:

# live object to be passed in a job and changed there
$liveObject = @{ data = 42}

# job script
$script = {
    param($p1)
    $p1.data # some output (42)
    $p1.data = 3.14 # change the live object data
}

# create and start the job
$p = [PowerShell]::Create()
$null = $p.AddScript($script).AddArgument($liveObject)
$job = $p.BeginInvoke()

# wait for it to complete
$done = $job.AsyncWaitHandle.WaitOne()

# get the output, this line prints 42
$p.EndInvoke($job)

# show the changed live object (data = 3.14)
$liveObject
