Is posible somehow add new index to exist array ?

Question

I would like to have an array. For example: int[] arr = new int[1];.
Use it in loops, and add new index [n+1].
It's simillar like List<int> li = new List<int>();.
Li.Add(x). I know I can use Lists, but array are simpler. Is there any option to use array as List ?

Answer 1

Regular arrays are static as I understand it, as you said in your question, a List is the preferred option when you need a dynamic container, not a regular array : )
