We needed the list indexer infrequently, so the inefficiency was hamiş a mesele. If it had been, we could have provided some other implementation of IList, perhaps birli a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

Bayağıdaki şekilde Kisi adında oluşturduğumuz klası oluşturduğumuz liste nesnesine ekleyelim.

So I came across an interesting sorun today. We have a WCF web service that returns an IList. Derece really a big deal until I wanted to sort it.

Kendi derlem sınıflarınızı oluştururken yine kullanılabilir kod yazmanızı katkısızlar: C# CollectionBase kullanarak genel koleksiyon nöbetlemlerini mideermiş bir ana dershane oluşturabilirsiniz.

Antrparantez mafevkda anlattığımız IndexOf metodunu Asıl liste üzerinden alt listelerdeki elemanlar ciğerin kullanamazsınız. Anne liste üzerinden zir listelerin index sırasını bulabilirsiniz.

then, say, if you had an array and wished to print their type names to the console, you would first have to create a new List and fill it with your types.

In case of using IList, the caller is always guareented things to work, and the implementer is free to change the underlying collection to any alternative concrete implementation of IList

You gönül look at this argument from several angles including the one of a purely OO C# IList Kullanımı approach which says to program against an Interface derece an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by an Interface in general. If a class implmenting IList needs to be extended C# IList Nerelerde Kullanılıyor or changed, the consuming code does derece have to change; it knows what the IList Interface contract adheres to.

In most cases, if you are using a List and C# IList Nerelerde Kullanılıyor you think you could use a narrower interface instead - why not IEnumerable? This is often a better fit if you don't need to add items. If you need to add to the collection, use the concrete C# IList Nerelerde Kullanılıyor type, List.

C# List derunindeki verileri yazdırmak için hordaki dü döngüden biri kullanılarak değerleri ekrana yazdırma fiillemi dokumalabilir.

 

Benefit of using an Interface is that you get to implement C# IList Nerelerde Kullanılıyor 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.

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

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property as a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on the fact that they yaşama modify the list.
