Question

以下代码可以按顺序完美地工作，但是我想使其并行运行。我还有很多其他功能要转换，并希望该功能成为我计划进行的所有转换的模板。我不知道哪个最好用。工作流或运行空间。我都没有成功。

Function New-TestCimSession {
  [CmdletBinding(
    SupportsShouldProcess = $true
  )]
  param(
    [Parameter(
      Position = 0,
      Mandatory = $false,
      ValueFromPipeline = $true,
      ValueFromPipelineByPropertyName = $True,
      HelpMessage = "Computer(s) you want to create a CimSession to")]
    [ValidateNotNullOrEmpty()]
    [string[]]
    $ComputerName = $env:COMPUTERNAME,

    [Parameter(
      Position = 1,
      Mandatory = $false,
      ValueFromPipelineByPropertyName = $True,
      HelpMessage = "Describe what the value of the parameter should be")]
    [ValidateNotNullOrEmpty()]
    [System.Management.Automation.Credential()]
    [System.Management.Automation.PSCredential]
    $Credential = [System.Management.Automation.PSCredential]::Empty
  )

  begin {
    Write-Verbose "New-TestCimSession: Started"
    Set-StrictMode -Version 1.0 #Option Explicit
    $ErrorActionPreference = 'Stop'
    $AllComputerObjects = [System.Collections.ArrayList]@()

    $SessionParams = @{
      ErrorAction = 'Stop'
    }
    $Opt = New-CimSessionOption -Protocol DCOM
    $SessionParams.SessionOption = $Opt

    if ($PSBoundParameters['Credential']) {
      $SessionParams.Credential = $Credential
    }
    else {
      $SessionParams.Credential = Get-Credential
    }
  }

  process {
    foreach ($Computer in $ComputerName) {
      $SessionParams.ComputerName = $Computer
      $SessionParams.SessionOption = $Opt

      $NewComputerObject = [PSObject] @{}
      $NewComputerObject | Add-Member -MemberType NoteProperty -Name 'ComputerName' -Value "$Computer"

      try {
        $NewComputerObject | Add-Member -MemberType NoteProperty -Name 'CimSession' -Value (New-CimSession @SessionParams)
      }
      catch {}

      if ($null -ne $NewComputerObject.CimSession) {
        $NewComputerObject | Add-Member -MemberType NoteProperty -Name 'CimSessionConnected' -Value $true
      }
      else {
        $NewComputerObject | Add-Member -MemberType NoteProperty -Name 'CimSessionConnected' -Value $false
      }
      $AllComputerObjects += $NewComputerObject
    }
  }

  end {
    Write-Verbose "New-TestCimSession: Completed"
    return , $AllComputerObjects
  }
}

有一些答案，但是我最了解的是使用Powershell Job。这是有关如何使用它们的示例：

$asyncBlock = {
  # Code to run asynchronously goes here
}

# Start the background job
$bgJob = Start-Job $asyncBlock

# Do other stuff here

# Wait for the background job to complete before continuing
$bgJob | Wait-Job

# Get the resulting output from the background job
$result = Receive-Job -Job $bgJob

如果您想完全异步运行New-TestCimSession，请像这样调用它：

$bgJob = Start-Job { New-TestCimSession -Arguments go -Here }
$bgJob | Wait-Job
$result = $bgJob | Receive-Job

然后将$result处理为该函数的输出。
