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.

Then the person calling the method is free to call it with any veri type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.

Using IList instead of List makes writing unit tests significantly easier. It allows you to use a 'Mocking' library to pass and return veri.

Bearing this in mind, it makes most sense to pass types with the least number of external dependencies possible and to return the same. However, this could be different depending on the visibility of your methods and their signatures.

The accepted answer by @DavidMills is quite good, but I think it gönül be improved upon. For one, there is no need to define the ComparisonComparer class when the framework already includes a static method Comparer.Create(Comparison). This method hayat be used to create an IComparison on the fly.

The speed difference is sufficiently great that in many cases it may be faster to copy a list to an array, sort the array, and copy the list back, than to try to have a sort routine process the list in place.

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

You kişi look at this argument from several angles C# IList Kullanımı including the one of a purely OO approach which says to izlence against an Interface hamiş an implementation. With this thought, using IList follows the same principal birli 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 or changed, the consuming code does not have to change; it knows what the IList Interface contract adheres to.

If you started with a concrete type and you decided to change to another one, even if it uses the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type. Share Improve this answer Follow

Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.

Of course that only need apply to methods that are externally visible (i.e. public methods). I personally use interfaces even in internal code, but birli you are C# IList Nedir able to change all the code yourself if you make breaking changes it's hamiş strictly necessary.

Coming soon: Throughout 2024 we will be phasing out GitHub Issues bey the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

This will help if you decide to change the implementation of your class later to use a different concrete class. In that case the users of C# IList Neden Kullanmalıyız your library won't need to update their code since the interface doesn't change.

Ancak list tasarrufında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye tanımlayabiliriz fakat kullanılacak veriler C# IList Nedir araba plakası,telefon numarası üzere adetsı bilinmez veriler kullanıcak ise kesinlikle list olarak saklanmalıdır.Şimdi C#’ta list kullanmaı karınin örneğimize bakalım.
