Powershell 在threadjob中使用SetImage

我有一个将图片插入PPT的功能，包括以下代码：

$file = get-item($pic);
$img = [System.Drawing.Image]::Fromfile($file);



[System.Windows.Forms.Clipboard]::SetImage($img);


$slide = $pp1.Slides.Item($targetslide)

Start-Sleep -Seconds 5

$shape = $Slide.Shapes.PasteSpecial($ppPasteJPG,$false,$null,$null,$null,$null)

但是，我创建了一个使用此函数的函数，并将其放入threadjob的操作脚本中。现在，当它被激活时，会产生错误：

Exception calling "SetImage" with "1" argument(s): "Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it."
At C:\...\PicInsertPPT.ps1:17 char:1
+ [System.Windows.Forms.Clipboard]::SetImage($img);
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ThreadStateException

我可以用什么替换该行，它将作为threadjob中的一个任务与多个并行任务一起工作

我正在考虑申请：

CommandBars.ExecuteMso("PictureInsertFromFile")

但我不完全确定如何控制以这种方式插入的图片

编辑：我的threadjob代码是：

Function ThreadMaster{



param ($folder)




$global:folder = $folder



  # Use the system's temp folder in this example.
  $global:dir = $folder

  # Define the tasks as an array of custom objects that specify the dir.
  # and file name pattern to monitor as well as the action script block to 
  # handle the events.

不确定在使用线程作业时是否可以控制单元状态。您可能需要直接使用运行空间重写。你有包含线程作业的函数代码吗？我不太确定你想要代码的哪一部分。我有一个Threadjob，它有两个操作块，一个用于Report1Generator，另一个用于Report2Generator。在Report2Generator中，它调用函数PicInsertPPT。PicInsertPPT的代码显然与多线程不兼容。请放入包含线程作业的代码并抛出此错误，以便人们可以复制、粘贴和复制。无论如何，您需要做的是用自定义运行空间替换线程作业，并将其单元状态设置为STA。在那里，我添加了它
