Question

I’m creating a CustomControl and I need my control has a collection that accept almost all kind of generic and none generic collection. For example List<T>, IEnumerable and etc.

Thanks in advance.

Answer 1

IEnumerable or IEnumerable<T> will accept most (possibly all) collections*.

_{* In fact, those are not, strictly speaking, collections – however, you mentioned IEnumerable in the question.}
