Question

我正在使用以下行在服务器上运行测试：

Get-WmiObject Win32_Service -ComputerName "myserver" -Filter "State='Running'" |
where-object ??? }| Foreach-Object {
                New-Object -TypeName PSObject -Property @{
                    DisplayName=$_.DisplayName
                    State=$_.State
                } | Select-Object DisplayName,State
            # Export all info to CSV
            } | ft -AutoSize

我想创建一个这样的变量：

$IgnoreServices = '"Wireless Configuration","Telephony","Secondary Logon"

并将其发送到Where-Object。我可以这样做吗？

编辑：经过一些R / T（研究和尝试:)）我发现我可以做到这一点：

$IgnoreServices = {$_.DisplayName -ne "Wireless Configuration" 
-and $_.DisplayName -ne "Telephony" -and $_.DisplayName -ne "Secondary Logon" 
-and $_.DisplayName -ne "Windows Event Collector"}

Get-WmiObject Win32_Service -ComputerName "myserver" -Filter   "State='Running'"|        where-object $IgnoreServices | Foreach-Object {
                # Set new objects for info gathered with WMI
                New-Object -TypeName PSObject -Property @{
                    DisplayName=$_.DisplayName
                    State=$_.State
                } | Select-Object DisplayName,State
            # Export all info to CSV
            } | ft -AutoSize

但是......如果可以通过以下方式指定要排除的服务，我真的很喜欢： “服务1”， “服务2”， “服务3”

与往常一样，非常感谢所有帮助!!

Answer 1

是的，你可以这样做：

$IgnoreServices = "Wireless Configuration","Telephony","Secondary Logon"

就像你想要的那样，在where-object中执行以下操作：

where-object { $IgnoreServices -notcontains $_.DisplayName  }

Answer 2

您可以使用WMI过滤器（运行速度更快），并且由于您只选择属性而无需创建新对象，因此请使用Select-Object cmdlet instaed：

$filter = "State='Running' AND Name <> 'Wireless Configuration' AND Name <> 'Telephony' AND Name <> 'Secondary Logon'"

Get-WmiObject Win32_Service -ComputerName myserver -Filter $filter | Select-Object DisplayName,State

从变量中过滤输出（where-object）
