All you have to do is loop through your ArrayList and then loop through your ArrayList that you're looping through :)

C#

ArrayList arr = new ArrayList();
arr.Add(new ArrayList(new[] { "value 1.1", "value 1.2" }));
arr.Add(new ArrayList(new[] { "value 2.1", "value 2.2" }));
arr.Add(new ArrayList(new[] { "value 3.1", "value 3.2" }));
foreach (ArrayList innerArr in arr)
{
	foreach (object element in innerArr)
	{
		// Do something with the elements.
	}
}

May I suggest you take a look at the List<T>[^] class though?
