How to insert value in a IEnumerable<int>?

Question

I have this :

IEnumerable<int> intYear = Enumerable.Empty<int>();

how can I insert some values? I Don't see any intYear.Add() method.

Like 2010, 2011, and so on...

Answer 1

You should use an IList<int> instead of IEnumerable<int> for that:

IList<int> intYear = new List<int>();
intYear.Add(2011);
// and so on

IList<T> implements IEnumerable<T> so you can pass it to any method taking an IEnumerable<T> as argument.
