Question

我想要isGooglePlayServicesAvailable的用户输入，但它不接受我的变量

我想运行以下命令：

Get-Service

问题在于它无法获得服务。

#### --- Content -- ### 
# - Location ##
$Service_text   = "$env:userprofile\documents\PS-Script-Services\Services.txt"

#- Test path
$service_test = Test-Path $Service_text

#-- Get-content ##-
$Get_the_service = Get-Content $service_text

#-loop-# -- Get-Service -- ##
if ($service_test -eq $false) {
  Write-Host "To view your Services go to Start --> en typ services, or go to Powershell and type get-service"
  Write-Host "Which Services do you want to monitor? (Example: Teamviewer, BITS, DHCP, Eventlog, Spooler."  -BackgroundColor Black -ForegroundColor Yellow
  Write-Host "This script only works when a service has been stopped" -BackgroundColor Black -ForegroundColor Yellow
  Read-Host "Enter services" | Out-File $service_text
  $ask_service = Get-Service -Name $Get_the_service

给了我这个输出：

Status   Name               DisplayName
------   ----               -----------
Running  dhcp               DHCP Client

但如果我想要多项服务

$Service_name  = "dhcp"

Get-Service -Name $service_name

我收到此错误：

Get-Service : Cannot find any service with service name 'dhcp, spooler'.
At line:5 char:1
+ Get-Service -Name $service_name
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (dhcp, spooler:String) [Get-Service], ServiceCommandException
    + FullyQualifiedErrorId : NoServiceFoundForGivenName,Microsoft.PowerShell.Commands.GetServiceCommand

Answer 1

没有名称为dhcp, spooler的服务。显然，您正在尝试获取服务列表（即dhcp和spooler）。为此，您必须将$Service_name定义为实际列表，而不是将逗号分隔的单词定义为单个字符串：

$Service_name = "dhcp", "spooler"

Answer 2

如果要检索多个服务，则必须将数组传递给Get-Service cmdlet。您可以使用-split将字符串拆分为数组并修剪任何空格：

Get-Service -Name ($Service_name -split ',' | % { $_.Trim() } )

Answer 3

“dhcp，spooler”是一个文字字符串。因此，当您将其传递给get-service时，Get-Service会查找名为 dhcp，spooler 的服务。相反，传递一个由逗号分隔的字符串“列表”。即'dhcp'，'假脱机' 然后你可以随心所欲地传递它。如果您要从文本文件中收集名称，请确保每个服务都在新行
