Powershell While循环无法按预期工作

Question

当我在While内的第二个提示中回答“ n”时，为什么我下面的示例中的While循环为什么又从“写主机“没有数据库，请键入文件名””重新开始，而跳过了而封锁

有什么主意吗？

$GetDb = Get-SqlDatabase -name "Data1" -ServerInstance "server\insta"

if ($GetDb) {
  Write-Host "Db exists!"
}
else {
  Write-Host "No db, please type filenames"
  $Prompt = Read-Host "Do you want add files?(y/n)"
    While ($Prompt-match "y") {
    $file1 = Read-Host "Type filename"
    $Prompt = Read-Host "Do you want to add more files?"
    }
}

谢谢
