How do I dynamically add elements to arrays in PowerShell?
$testArray = [System.Collections.ArrayList]@()$tempArray = "123", "321", "453"foreach($item in $tempArray){ $arrayID = $testArray.Add($item)}
The problem is one of scope; inside your addToArray function change the line to this:
$script:testArray += $Item1...to store into the array variable you are expecting.
If you are going to play with a dynamic amount of items, a more precise solution might be using the List:
$testArray = New-Object System.Collections.Generic.List[System.Object]$tempArray = "123", "321", "453"foreach($item in $tempArray){ $testArray.Add($item)}Note: In this case you get the power of the List from .Net, so you can easily apply linq, merge, split, and do anything which you'd do with the List in .Net
