En iyi Tarafı C# IList Nedir

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list. This code is part of a larger example for the IList interface.

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

Interface’ler için daha ziyade fen olmak isterseniz, kötüdaki kaynaklara nazar atabilirsiniz:

Sıfır ast limitına mevla biricik boyutlu diziler kendiliğinden olarak uygular IList. Bu, diziler ve diğer derlem türleri ortada yineleme çıkarmak karınin aynı kodu kullanabilen umumi yöntemler oluşturmanıza imkân tanır.

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 not.

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you kişi't justify it, use the interface.

Object güç be a T too. Doing this will save you headache if you decide to use a Stack or some other veri structure further down the road. If all you need to do in the function is foreach through it, IEnumerable is really all you should be asking for.

If you specify C# IList Nerelerde Kullanılıyor your methods to return an interface that means you are free to change the exact implementation later on without the consuming method ever knowing.

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. You have to weigh their ability to C# IList Nerelerde Kullanılıyor make full use of the object against their ability to easily use a portion of the objects functionality (and of course whether you WANT them to be making full use of the object).

It is like this other question. The other question shares a lot of common ground, but is arguably not a true duplicate. In either case though, this is not opinion-based. What may C# IList Nedir have happened is that the closer might have just looked at this question's title, without reading the question itself. The body is objective.

Veri Depolama: Uygulamalarda sâri verileri yahut işleme sırasında oluşan verileri depolamak derunin kullanılabilir.

So typically, your methods should accept and return interfaces for collections. This leaves your own implementation and your callers C# IList Kullanımı room to decide on the actual implementation kakım required.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they kişi't add or remove items from your object, they emanet only act against the objects. If you need to expose a collection outside of a class, but don't want to let the caller change the collection, this is one way of doing it. On C# IList Kullanımı the other hand, if you are returning an empty collection that you expect/want them to populate, then an IEnumerable is unsuitable.
