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

I don't totally disagree with the sentiment of over-architecture being a real sıkıntı. However I think that especially in the case of collections that interfaces really shine.

Elemanların Sıralı Yapısını Dulda: IList, elemanların eklenme sırasını korur. Bu özellik, bilgi yapısının sıralı olmasını ve izlenceın beklentilerine müsait çallıkışmasını esenlar.

All concepts are basically stated in most of the answers above regarding why use interface over concrete implementations.

In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.

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.

Most app-level code (i.e. the everyday code that ou write for your application) should probably focus on the generic versions; however there is also a lot of infrastructure code around that must use reflection.

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

In VS2008, when I click on the service reference and select C# IList Nerelerde Kullanılıyor "Configure Service Reference", there is an option to choose how the client bile-serializes lists returned from the service.

It really comes down to the kind of functionality you need. I'd suggest using the List class in most cases. IList is best for when you need to make a custom array that could have some very specific rules that you'd like to encapsulate within a collection so you don't repeat yourself, C# IList Nerelerde Kullanılıyor but still want .Kemiksiz to recognize it birli a list.

private List _numbers; // callers yaşama add/update/remove elements, but cannot C# IList Kullanımı reassign a new list to this property

List communicates "I need to get and seki the elements of this sequence in arbitrary order and I only accept lists; I do hamiş accept arrays."

for your return types. This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.

IEnumerable allows you to iterate through a collection. ICollection builds on this C# IList Nasıl Kullanılır 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 C# IList Nedir 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 birli 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 kişi modify the list.
