I know there has been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.

Lütfen zirdaki kutuya şikayetinizin bilgilerinı gökçe yazın. Şikayetinizi değerlendirildikten sonra size marifet vereceğiz.

Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, derece add or remove. Accepting an interface birli a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

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

Use whatever you want. It's your method. You're the only one who gets to see the internal implementation details of the method.

Örneğin, zirdaki kodda bir IAnimal tipinde bir değişken teşhismladım ve bu bileğhizmetkene Dog ve Cat nesneleri atadım.

Dizilerde evetğu kabil başta kaç pare elemanla çtuzakışılacağı belirtilmek zorunda değildir. Dizilerde olduğu üzere eleman ekleme, silme C# IList Kullanımı maslahatlemleri uygulanabilir ve araya eleman eklenebilir. Rabıtlı listeler esenladığı avantajlardan dolayı henüz çok tercih edilir.

IList is derece a class; it's an interface that classes hayat implement. The interface itself is just a contract C# IList Nedir between the consumer of the class and the class itself. This line of code will work:

Benefit of using an Interface is that you get to implement your functionality or better yet, the only functionality you require. So, if iteration/enumeration is C# IList Nerelerde Kullanılıyor required only, then there is no need for the Sort, Add methods.

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

So I have been playing around with some of my methods on how to do this. I am still not sure about the return type(if I should make it more concrete or an interface).
