启动-作业-ScriptBlock:检索在ScriptBlock中编译的数组

Question

我在构建数组的ScriptBlock中有一个Foreach循环。当数组完成后，我想不出如何从作业中检索数组。

这是我目前的密码。

$HSMissingEmail = New-Object System.Collections.ArrayList
$HSDataObjects = New-Object System.Collections.ArrayList

$HSMissingEmail = Start-Job -Name HSMissingEmailStatus -ScriptBlock {
    param($HSDataObjects, $HSMissingEmail);
    foreach ($HSDO in $HSDataObjects) {
      $HSDO = $HSDO | Select-Object Name, Location, Telephone, EmailAddress, Comments;
      if ($HSDO | Where-Object {$_.EmailAddress -like ""}) {
        $HSMissingEmail.Add($HSDO)
      }
    }
  } -HSDataObjects $HSDataObjects -HSMissingEmail $HSMissingEmail | Receive-Job -Name HSMissingEmailStatus

我也尝试过以下方法，但是它也没有做任何事情。

$HSMissingEmail = New-Object System.Collections.ArrayList
$HSDataObjects = New-Object System.Collections.ArrayList

$ScriptBlock = 
    {
        param($HSDataObjects,$HSMissingEmail)
        foreach ($HSDO in $HSDataObjects)
        {
            $HSDO = $HSDO | Select-Object Name, Location, Telephone, EmailAddress, Comments

            if ($HSDO | Where-Object {$_.emailaddress -like ""})
                {
                    $HSMissingEmail.Add($HSDO)
                }
        }
    }
    Start-Job -Name HSMissingEmailStatus -ScriptBlock $ScriptBlock -HSDataObjects $HSDataObjects -HSMissingEmail $HSMissingEmail
    ProgressBar ([REF]$HSMissingEmailStatus)
    $HSMissingEmail = Receive-Job -Name HSMissingEmailStatus
    Get-job -Name HSMissingEmailStatus | Remove-Job

我尝试过许多不同的方法来形成ScriptBlock，但是没有人会将任何东西返回给$HSMissingEmail。

另外，第二个代码块在使ScriptBlock全部一行之前不会获得传递的数据，我不确定这是否是默认行为。

如何检索数组？

Answer 1

您需要将数组写入标准输出。

$HSMissingEmail = New-Object System.Collections.ArrayList
$HSDataObjects = New-Object System.Collections.ArrayList

$HSMissingEmail = Start-Job -Name HSMissingEmailStatus -ScriptBlock {
    param($HSDataObjects, $HSMissingEmail);
    foreach ($HSDO in $HSDataObjects) {
      $HSDO = $HSDO | Select-Object Name, Location, Telephone, EmailAddress, Comments;
      if ($HSDO | Where-Object {$_.EmailAddress -like ""}) {
        $HSMissingEmail.Add($HSDO)
      }
    }
    $HSMissingEmail    # Drops it out as a result of the script block
  } -HSDataObjects $HSDataObjects -HSMissingEmail $HSMissingEmail
Receive-Job -Name HSMissingEmailStatus -Wait  # At the appropriate time, or keep cycling until you get it all

至于单行/多行位，如果没有显式地将变量键入为ScriptBlock，可能会出现问题，但我必须检查。
