Foreach-Object -Parallel return result

Question

Hello,

I am working on a script that i would like to execute in parallel but it has to return command results, how can I do this?

Example :
I woulfd like to use the $something var outside of the foreach-object, (here to print all the data gathered in the loop)

$test = "a test"
Import-Csv $CSV_file -Delimiter ";" | ForEach-Object -Parallel {
    Write-host $using:test
    $someting += "some result`n"
} -ThrottleLimit 5

Write-Host $something

Hi,

You may try this.

$someting = @{result1=@();result2=@()}  
$test = "a test"  
Import-Csv $CSV_file -Delimiter ";" | ForEach-Object -ThrottleLimit 5 -Parallel {  
     Write-host $using:test  
    ($using:someting).result1 += "some result 1 `n"  
	($using:someting).result2 += "some result 2 `n"  
}  
$someting.result1  
$someting.result2
