Prevent ArrayList.Add() from returning the index

is there a way to supress the return value (=Index) of an ArrayList in Powershell (using System.Collections.ArrayList) or should I use another class?

$myArrayList = New-Object System.Collections.ArrayList($null)
$myArrayList.Add("test")
Output: 0

You can cast to void to ignore the return value from the Add method:

[void]$myArrayList.Add("test")

Another option is to redirect to $null:

$myArrayList.Add("test") > $null

Two more options :)

Pipe to out-null

$myArrayList.Add("test") | Out-Null

Assign the result to $null:

$null = $myArrayList.Add("test")
