Same principle kakım before, reversed. Offer the bare asgari that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return veri.

Emanet a unique position be deduced if pieces are replaced by checkers (yaşama see piece color but not type)

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.

In some code this dirilik be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to call this seki of methods, no other contract implied."

List implements IList, and so gönül be assigned to the variable. There are also other types that also implement IList.

In fact, any time you are using reflection IList is more convenient than IList-of-T, since generics and reflection don't play nicely together. It yaşama be done, but it is a pain. Unfortunately since IList-of-T doesn't derive from IList there are cases where this hayat fail - but it is a good 95% rule.

The idea is that you hide the implementation details from the user, and instead provide C# IList Nasıl Kullanılır them C# IList Kullanımı with a stable interface. This is to reduce dependency on details that might change in the future.

However, this makes the method more fragile, kakım any change to the returned C# IList Nasıl Kullanılır object type may break the calling code. In practice though, that generally isn't a major sıkıntı.

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked as helpful. However, I would add that for most developers, most of the time, the tiny difference in izlence size and performance is derece worth worrying about: if in doubt, just use a List.

for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.

Bu şekilde, Dog dershaneı IAnimal interface’inin sözleşmesine uymuş olur. Aynı şekilde, değişik efsanevi sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, aşağıdaki kodda bir Cat derslikı tanımladım ve IAnimal interface’ini uyguladım.
