When to use ArrayList over array[] in c#?

Question

I often use an ArrayList instead of a \'normal\' array[].

I feel as if I am cheating (or being lazy) when I use an ArrayList,

Answer 1

Well for one, if you only intend to handle a specific type, you shouldn't use an ArrayList. For example, if you only expect an array of bytes, you should only accept an array of bytes.

Only time I would think you may even think of using an ArrayList is instead of List.
