How can I create an ArrayList with a starting index of 1 (instead of 0)

Question

How can I start the index in an ArrayList at 1 instead of 0? Is there a way to do that directly in code?

(Note that I am asking for ArrayList

Answer 1

Here is something I am using right now to quickly port a VBA application to C#:

It's an Array class that starts with 1 and accepts multiple dimensions.

Although there is some additional work to do (IEnumerator, etc...), it's a start, and is enough to me as I only use indexers.

public class OneBasedArray
{
    Array innerArray;

    public OneBasedArray(params int[] lengths)
    {
        innerArray = Array.CreateInstance(typeof(T), lengths, Enumerable.Repeat(1, lengths.Length).ToArray());
    }

    public T this[params int[] i]
    {
        get
        {
            return (T)innerArray.GetValue(i);
        }
        set
        {
            innerArray.SetValue(value, i);
        }
    }
}
