Question

I’ve just started learning C# and in the introduction to arrays they showed how to establish a variable as an array but is seems that one must specify the length of the array at assignment, so what if I don’t know the length of the array?

Answer 1

Arrays must be assigned a length. To allow for any number of elements, use the List class.

For example:

List<int> myInts = new List<int>(); myInts.Add(5); myInts.Add(10); myInts.Add(11); myInts.Count // = 3
