You cannot predict the future. Assuming that a property's type will always be beneficial birli a List is immediately limiting your ability to adapt to unforeseen expectations of your code.

Başarım Optimizasyonu: IList, done erişimini optimize ederek uygulamanın performansını artırabilir ve kafa yönetimini iyileştirebilir.

So I came across an interesting sorun today. We have a WCF web service that returns an IList. Not really a big deal until I wanted to sort it.

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.

Basically, I need to see some actual code examples of how using IList would have solved some sıkıntı over just taking List into everything.

IList on the other hand is an Interface. Basically, if you want to create your own custom List, say a list class called BookList, then you yaşama use the Interface to give you basic methods and structure to your new class. IList is for when you want to create your own, special sub-class that implements List.

You are most often better of using the most general usable type, in this case the IList or even better the IEnumerable interface, so that you emanet switch the implementation conveniently at a later time.

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

If you are exposing your class through a library that others C# IList Nasıl Kullanılır will use, you generally want to expose it via interfaces rather than concrete implementations.

If you code your own class implementing the IList interface, make sure you also implement the non-generic IList interface, or the code will işleyen with C# IList Neden Kullanmalıyız a class cast exception.

I know that IList is the interface and List is the concrete type but I still don't know when to use each one. What I'm C# IList Kullanımı doing now is if I don't need the Sort or FindAll methods I use the interface. Am C# IList Neden Kullanmalıyız I right? Is there a better way to decide when to use the interface or the concrete type?

Bu örnekte, Student isminde bir sınıf ve StudentCollection isminde CollectionBase klasından türeyen özel bir derlem klası oluşturduk.

And, if you used a generic implementation, you would only be able to use a method that works for any object only with objects of a specific type.

The other general reason for using interfaces is to expose the minimum amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a data object that implements IList.
