C# IList Nedir Seçenekler

Note that, if your API is only going to be used in foreach loops, etc, then you might want to consider just exposing IEnumerable instead.

Bu şekilde listelerin birbirini point etmesi ve bağlamlı listenin elemanlarına paha verilmesi sağlanmaktadır.

Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does derece contain an array, so all of a sudden, we had almost no use of the large object heap.

I leave this up to show that if you needed to do it (e.g. the off chance a third party library returned a List that you needed to convert for another 3rd party library), you sevimli do it this way.

If you use the concrete type all callers need to be updated. If exposed bey IList the caller doesn't have to be changed.
