$objForm.Controls.Add($CancelButton)

[void] $objForm.ShowDialog()

write-host $acns

当我把＆＃34; Get-Mailbox -Identity $ acns＆＃34;在脚本的最后它按预期工作。但是当我放入add_click

时却没有

GUI应用程序没有控制台，因此通常的“将每个未保存的对象抛出到控制台”都不适用。您需要指定它应该与ex一起进入控制台。 Out-Default，Out-Host（Out-Default发送给），或转换为字符串并显示，例如

Get-Mailbox -Identity "$acns" | Out-Default
Get-Mailbox -Identity "$acns" | Out-Host
#Since you're still in the GUI-application you won't be able to use the output anyways, so you might as well print it as a string
Get-Mailbox -Identity "$acns" | Out-String | Write-Host

请记住：命令仍然可以工作，对象可以通过管道输送到Set-Mailbox等。这只是需要特别注意的控制台输出。我建议使用GUI进行用户输出或完全跳过GUI /单击关闭它，让控制台显示其余部分。混合只是混乱。
