"Are there any simple groups that appear as zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?
Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.
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 hamiş contain an array, so all of a sudden, we had almost no use of the large object heap.
Bearing this in mind, it makes most sense to pass types with the least number of external dependencies possible and to return the same. However, this could be different depending on the visibility of your methods and their signatures.

This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you dirilik be sure that your list is not going to be modified. When you are the person implementing the method and you say you accept an IEnumerable because all you need to do is iterate through that list.
The cost to do this is minimal, why not save yourself the headache later? It's what the interface principle is all about.

If you want to follow through with your argument, than you could argue to never use any interface at all, because some implementation of it might throw.
Whether you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created C# IList Neden Kullanmalıyız -- this is an API design decision, and there's no hard and fast rule. You have to weigh their ability to make full use of the object against their ability to easily use a portion of the objects functionality (and of course whether you WANT them to be making full use of the object).

List communicates "I need to get C# IList Neden Kullanmalıyız and set the elements of this sequence in arbitrary order and I only accept lists; I do not accept arrays."
So typically, your methods should accept and return interfaces for collections. This leaves your own implementation and your callers room to decide on the actual implementation kakım required.
Bu şekilde, Dog derslikı IAnimal C# IList Kullanımı interface’inin sözleşmesine uymuş evet. Aynı şekilde, başka hayvan sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, kötüdaki kodda bir Cat klası teşhismladım ve IAnimal interface’ini uyguladım.
