I want to populate an int variable with the last index of an ArrayList. I haven't yet found a property of ArrayList that will do that for me and I'm wondering if I'm missing something. Right now I am doing it this way:
int theLastIndex = theArrayList.Count - 1
But I'm wondering if there is a more elegant way.
This is in C#, by the way.
Thanks in advance.

Normally, though, you should avoid basing too much logic around the last index of the array/ArrayList, and instead just use the size. Then instead of looping while, say, i <= lastIndex, you loop while i < arrayList.Count. This is something that I didn't do when I was first learning java, so I frequently had off-by-one errors, etc.
I don't know the specific situation you're in, though, so disregard that info if you already knew it or it doesn't apply.

A teeny weeny bit more elegent, if you're into that sort of thing:
int lastIndex = theArrayList.Count++;
