Loops powershell中的结束循环

嘿，伙计们

我希望在脚本中有一个循环，但当我使用else时，它需要停止

do {


##script##



if ((Get-Service $service ).Status -eq "stopped") {
Write-Host 'Send email message, a service has been stopped'
Send-MailMessage -From $From -to $To -Subject $Subject `
-Body $Body -SmtpServer $SMTPServer -port $SMTPPort -UseSsl `
-Credential $mycredentials -Attachments $service_text -ErrorAction SilentlyContinue
$stopen = "stoppen"
}
else { write-host "re execute script" } while ((Get-Service $service ).Status -eq "stopped")
}

如何在else语句中结束循环

谢谢

看完整的脚本，错误在脚本的末尾。 如果服务正在运行，脚本需要再次检查它。如果服务停止，我需要收到一封电子邮件。不，我不想收到2亿封电子邮件，只要一封：P

使用

break

关键字中断循环：

$i = 0
do{
  if($i -lt 5)
  {
    $i++
  }
  else
  {
    break
  }
} while ($true)

或者正确使用

while（）

子句：

$i = 0
do{
  $i++
} while ($i -lt 5)

在

break

之前在

else

blockelse{write host“re-execute script”；break}准确，然后

while（（Get Service$Service）.Status-eq“stopped”）

在

do{}

块之外它不工作：（如果服务正在运行，脚本必须再次运行。如果服务已停止，我需要接收电子邮件。如果服务已停止，您是否应该尝试启动该服务？或者您是否只想继续发送垃圾邮件，直到有人联机并手动启动该服务？因此，如果服务正在运行，您希望保留

do{}（

循环永远运行，检查状态？如果服务在某一点停止怎么办？循环是否仍应继续？限制电子邮件？引入延迟？
