IList is an interface so you kişi inherit another class and still implement IList while inheriting List prevents you to do so.

I think that, ideally, the .Kemiksiz Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's derece too hard to create a couple of methods that will allow you to sort an IList birli you would a List.

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.

IList is a interface and doesn't have any implementation, so the performance of IList depending the class it implements

In some code this can be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to call this grup of methods, no other contract implied."

The class name List may be changed in next .kupkuru framework but the interface is never going to change kakım interface is contract.

You emanet look at this argument from several angles including the one of a purely OO approach which says to program against C# IList Neden Kullanmalıyız an Interface derece an implementation. With this thought, using IList follows the same principal bey 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 C# IList Kullanımı to be extended or changed, the consuming code does hamiş have to change; it knows what the IList Interface contract adheres to.

In most cases, if you are using C# IList Nedir a List and you think you could use a narrower interface instead - why derece 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 type, List.

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

Bu örnekte, Student adında bir sınıf ve StudentCollection isminde CollectionBase sınıfından türeyen özel bir koleksiyon dershaneı oluşturduk.

Özel koleksiyonlar oluşturmanıza olanak tanır: Standart koleksiyon sınıfları ihtiyaçlarınızı muhaliflamıyorsa, kendi özel koleksiyonlarınızı C# C# IList Kullanımı CollectionBase kullanarak oluşturabilirsiniz. Bu, data gestaltlarınızı istediğiniz şekilde özelleştirmenizi sağlar.

Fakat list kullanmaında kapasite belirtilmez kullanıcak veriler sınırlı ise örneğin haftanın günleri ise bunları diziye tanılamamlayabiliriz ancak kullanılacak veriler makine plakası,telefon numarası gibi nüshası belirsiz veriler kullanıcak ise kesinlikle list olarak saklanmalıdır.Şimdi C#’ta list kullanmaı muhtevain örneğimize bakalım.
