I have an array of buttons
        private Button[] Level = new Button[10];

if i pass Level[5] to a method.   How can I, in that method, access Level[4] or Level[6].  In C I can treat it like a pointer and get to any members..

thanks!

Short answer, you can't. Single elements of arrays have no knowledge of their container. What you can do is modify your function to accept 2 arguments. The first argument would be the array containing the buttons and the second argument would be the index of the item you wish to focus on.

I have, in the past, added custom collections and subclassed controls so they can reference their containers but that's a bit of effort to implement well for very little return. I'd just go with the 2 argument approach if I were you.

thanks!  I know C# is designed to not use pointers.
