Powershell script to Stop and start windows Service using S.no - powershell

Question

I have a listed my Windows Service Names in the Text file and I have added the code to display it by adding the S.no preceding to the Names,
Listofservices.txt contains
Print Spooler
Windows Update
Remote Desktop Services
Get-Content 'C:\Services\Listofservices.txt' | ForEach-Object { $i = 1 } { "$i.$_" ; $i++ }
Result
Print Spooler
Windows Update
Remote Desktop Services
now I would like to stop, start the services by entering only the S.no and I don't want to type the exact full name
$userinput = read-host -prompt "Enter the S.no to Stop/Start"
Stop-Service -Name "$userinput" -Force -Confirm
say for example if i enter the number 1 the Print Spooler service will be stopped

Answer 1

Here is one way you could do it following the code you already have, but as stated in comments, this is much simpler to do with Out-GridView -PassThru. Also do note, for these services, the PowerShell process will most likely require to be elevated.
$file = Get-Content path\to\file.txt
$file | ForEach-Object { $i = 1 } { "$i.$_" ; $i++ }
$userinput = Read-Host "Enter the S.no to Stop/Start"
try {
$choice = $file[-1 + $userinput]
if(-not $choice) {
throw 'Invalid selection..'
}
$service = Get-Service $choice
if('Running' -eq $service.Status) {
$service.Stop()
"$($service.Name) has been stopped.."
return # end the script here
}
$service.Start()
"$($service.Name) has been started.."
}
catch {
if($_.Exception.InnerException.InnerException.NativeErrorCode -eq 5) {
return "Process needs to be elevated."
}
"An error ocurred: $_"
}
