Question

试图找出如何通过PowerShell脚本获取运行服务的计数。我知道Get-Service将为我们提供系统上所有进程的列表和（Get-Service）。伯爵会给予计数。但问题是我们如何才能在系统中找到Running Services的计数？我简化了过滤条件，以获取仅Get-Service | Where-Object {$_.Status -eq "Running"}运行服务的列表，但这些服务的数量没有任何问题。

<强> TL; DR

(Get-Service | Where-Object Status -eq "Running").Count

您是否听说过Get-Member CmdLet？

如果没有;在这里阅读：https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/get-member?view=powershell-6

获取对象的属性和方法。

在类似的情况下，我发现这是最有用的命令之一。习惯使用它，因为它会非常方便！

这对你有什么帮助？嗯......

Get-Service | Get-Member

返回：

不是很酷吗？！

快速查看可用的属性（Get-Service | Get-Member -MemberType Property） - 发现有用的东西吗？

(Get-Service | Where-Object Status -eq "Running").Count
