Else use List. You birey't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List derece an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

Today, you almost always use IList, the primary reason for IList to still be around is for reasons of backwards compatibility.

Also, it casts IList to IList which özgü the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is derece guaranteed and gönül lead to brittle code.

Kendi derlem sınıflarınızı oluştururken yeni baştan kullanılabilir şifre yazmanızı sağlar: C# CollectionBase kullanarak genel derlem konulemlerini karınermiş bir baş derslik oluşturabilirsiniz.

In this specific case since you're essentially talking about a language construct, not a custom one it generally won't matter, but say for example that you found List didn't support something you needed.

Architecture Astronauts. The chances you will ever write your own IList that adds anything to the ones already in the .Safi framework are so remote that it's theoretical jelly tots reserved for "best practices".

I thought I'd never need to change from a List but had to later change to use a custom list library for the extra functionality it C# IList Kullanımı provided. Because I'd only returned an IList none of the people that used the library had to change their code.

Don't you know in advance if your method needs a list that gönül take additional members; don't you specify that in the method signature? What exactly were you going to do if you were passed a read only list like int[]?

the method, it C# IList Nasıl Kullanılır sevimli make a huge difference -- if they have an array and you're asking for a list, they C# IList Nedir have to change the array to a list or v.v. whenever calling the method, a total waste C# IList Nasıl Kullanılır of time from both a programmer and performance POV.

Returning a read-only interface such bey IEnumerable is often the way to go for data-retrieval methods. Your consumer can project it into a richer type kakım-needed.

If you're just enumerating over the values, you should be using IEnumerable. Every type of datatype that birey hold more than one value implements IEnumerable (or should) and makes your method hugely flexible.

Bu şekilde, Dog klası IAnimal interface’inin sözleşmesine uymuş olabilir. Aynı şekilde, değişik efsanevi sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, aşağıdaki kodda bir Cat klası tanılamamladım ve IAnimal interface’ini uyguladım.
