title: Array that can be resized fast
body: <p>I'm looking for a kind of array data-type that can easily have items added, without a performance hit.</p>
  
  <ul>
  <li>System.<strong>Array</strong> - <code>Redim Preserve</code> copies entire RAM from old to new, as slow as amount of existing elements</li>
  <li>System.Collections.<strong>ArrayList</strong> - good enough?</li>
  <li>System.Collections.<strong>IList</strong> - good enough?</li>
  </ul>
