    There is no two dimensional array list. Depending on what you need, you can use a two dimensional array, an arraylist of arraylists or an arraylist of points. Maybe a SortedList would do. ( Hint: SortedList in .NET is not a sorted list. )

    When in doubt, read the FAQ.
    Then ask a smart question.

    This is how to create one:

    ArrayList arrayList = new ArrayList();
    for (int i = 0; i < d1 ; i++)
    ArrayList l2 = new ArrayList(); arrayList.Add(l2);
    d1 is the length of the first dimension. At this point the variable arrayList is an ArrayList that has other ArrayLists as items. This is kind of pointless in my opinion, but it should work.
