Note that the IsReadOnly flag comes from ICollection, and indicates whether items yaşama be added or removed from the collection; but just to really confuse things, it does derece indicate whether they güç be replaced, which in the case of Arrays (which return IsReadOnlys == true) güç be.

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

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

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 hamiş 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.

Whether C# IList Nasıl Kullanılır you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created -- 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 C# IList Kullanımı use a portion of the objects functionality (and of course whether you WANT them to be making full use of the object).

IList is derece a class; it's an interface that classes birey implement. The interface itself is just a contract between the consumer of the C# IList Nasıl Kullanılır 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 required only, then there is no need for the Sort, Add methods.

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

The other general reason for using interfaces is to expose the minimum amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a veri object that implements IList.
