How I can pass multiple array in value in PowerShell function - powershell

Question

Below function I want to pass multiple value in array. When I'm passing more than one value I am getting an error.
function CheckProcess([String[]]$sEnterComputerNameHere, [String[]]$sEnterProccessNameHere) {
#Write-Host " $sEnterComputerNameHere hello"
#($sEnterComputerNameHere) | ForEach-Object {
# Calling Aarray
#($sEnterProccessNameHere) | ForEach-Object {
if (Get-Process -ComputerName $sEnterComputerNameHere | where {$_.ProcessName -eq $sEnterProccessNameHere}) {
Write-Output "$_ is running"
} else {
Write-Output "$_ is not running"
}
}
}
}
$script:sEnterProccessNameHere = #("VPNUI") # Pass the process agreement here
$script:sEnterComputerNameHere = #("hostname") # Pass the process agreement here
CheckProcess $sEnterComputerNameHere $sEnterProccessNameHere

Answer 1

Give it a try with this one:
Function CheckProcess([String[]]$sEnterComputerNameHere,[String[]]$sEnterProccessNameHere)
{ #Write-host " $sEnterComputerNameHere"
#($sEnterComputerNameHere) | Foreach-Object {
$computer = $_
Write-Host $computer
#($sEnterProccessNameHere) | Foreach-Object {
$process = $_
Write-Host $process
try{
$x = get-process -computername $computer #Save all processes in a variable
If ($x.ProcessName -contains $process) #use contains instead of equals
{
Write-Output "$process is running"
}
else
{
Write-Output "$process is not running"
}
}
catch
{
Write-Host "Computer $computer not found" -ForegroundColor Yellow
}
}
}
}
$script:sEnterProccessNameHere = #("VPNUI","Notepad++","SMSS")
$script:sEnterComputerNameHere = #("remotecomputer1","remotecomputer2")
CheckProcess -sEnterComputerNameHere $sEnterComputerNameHere -sEnterProccessNameHere $sEnterProccessNameHere
In general, it would be great if you write the error you get in your question. That helps others to help you.
If I work with arrays and | Foreach, I always write the $_in a new variable. That helps if I have another | Foreach (like you had) to know for sure, with which object I'm working with..
EDIT: I changed the script, so it uses "-contains" instead of "-eq" and I added a try/catch block, so if the other computer is not found, it gives you a message.. It works on my network
EDIT2: Do you have access to the other computers? If you run get-process -computername "name of remote computer" do you get the processes?
