Note that, if your API is only going to be used in foreach loops, etc, then you might want to consider just exposing IEnumerable instead.

Kendi koleksiyon sınıflarınızı oluştururken tekrar kullanılabilir şifre yazmanızı sağlar: C# CollectionBase kullanarak genel derlem nöbetlemlerini mideeren bir taban sınıf oluşturabilirsiniz.

Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does hamiş.

You yaşama have an instance of an interface, but you need to initialize it with a class that implements that interface such as:

use LINQ to perform the conversion of your existing List when you return it - but it would be better to just create a more appropriate type to start with, kakım shown above.

If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does derece apply to collections where elements are conceptually grouped into buckets, such birli a hash table.

Whether 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.

But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself C# IList Kullanımı to a specific implementation, especially if you have no control over who compiles against your code afterward.

Bu örnekte, Student isminde bir sınıf ve StudentCollection isminde CollectionBase klasından türeyen özel bir koleksiyon derslikı oluşturduk.

In particular, IList lets you use the indexer, and add/remove items; things that C# IList Nasıl Kullanılır IEnumerable don't let you do.
