title: Prevent ArrayList.Add() from returning the index
body: <p>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?</p>
  <pre><code>$myArrayList = New-Object System.Collections.ArrayList($null)
  $myArrayList.Add(&quot;test&quot;)
  Output: 0
  </code></pre>
