您也许了解了如何用脚本打开一个 MsgBox 对话框。今天，您将学习如何用一段代码打开一个 MsgBox，同时播放一段随机的音效，吸引用户的注意力并增加趣味性。当用户操作 MsgBox 的时候，音效立即停止：

$randomWAV = Get-ChildItem -Path C:\Windows\Media -Filter *.wav |
  Get-Random |
  Select-Object -ExpandProperty Fullname

# load Forms assembly to get a MsgBox dialog
Add-Type -AssemblyName System.Windows.Forms

# play random sound until MsgBox is closed
$player = New-Object Media.SoundPlayer $randomWAV
$player.Load();
$player.PlayLooping()
$result = [System.Windows.Forms.MessageBox]::Show("We will reboot your machine now. Ok?", "PowerShell", "YesNo", "Exclamation")
$player.Stop()
