try-catch bypassing a step - function

Question

I have a script that tests connection to a list of servers, and if contactable, gets the status of a service, and puts the results into three variables, $Computer, $Ping (True/False), and $Service (Running or Stopped).
The output is in a hashtable but I can only get to show the servers that ARE contactable, and not the ones that cannot be contactable.
I have placed a try/catch in the $Ping block, as well as -ErrorAction Stop, so that it doesn't attempt to run the $Service script, and instead go to the next $Computer in the array. I think I am trying to do two things at once that are conflicting each other:
add the variables to the #Splat and
don't process any further.
There are actually many more remote registry queries in my script, which will be irrelevant if the $Computer cannot be contactable, but I have shortened it for this post.
Function Get-Ping {
$Servers = (gc "c:\temp\test.txt")
foreach ($Computer in $Servers) {
Write-Host
Write-Host "---------------------------------"
Write-Host "QUERYING $Computer"
Write-Host
Write-Host "Performing ping test..."
try {
$Ping = Test-Connection $Computer -Count 1 -ErrorAction Stop
} catch {
Write-Warning "Cannot Ping $Computer"
Write-Host "Trying next computer..."
Write-Host
continue
}
if ($Ping) {$Ping="$True"}
Write-Host $Computer "can be pinged"
$svcRRStopped = $false
if ($Computer -ne $env:COMPUTERNAME) {
Write-Host "Check RemoteRegistry status..."
}
$svcRR = Get-Service -ComputerName $Computer -Include RemoteRegistry
$SelectSplat = #{
Property = (
'Computer',
'Ping',
'Service'
)}
New-Object -TypeName PSObject -Property #{
Computer=$Computer
Ping=$Ping
Service=$svcRR.status
} | Select-Object #SelectSplat
}
}
$results = Get-Ping
$tableFragment = $results | Select 'Computer','Ping','Service'
$tableFragment

Answer 1

Don't make things more complicated than they need to be.
function Get-Ping {
Get-Content 'C:\temp\test.txt' | ForEach-Object {
$isAvailable = [bool](Test-Connection $_ -Count 1 -EA SilentlyContinue)
if ($isAvailable) {
$rreg = Get-Service -Computer $_ -Name RemoteRegistry |
Select-Object -Expand Status
} else {
$rreg = 'n/a'
}
New-Object -Type PSObject -Property #{
Computer = $_
Ping = $isAvailable
Service = $rreg
}
}
}
Get-Ping

You can simply use the -Quiet Parameter:
Test-Connection $_ -Count 1 -Quiet
