Bu sayede menent done kuruluşlarını gene yeniden tevlit etmek adına, var olan kodu yine kullanabilirsiniz.

But far more importantly, if you are accepting an IList as a parameter you'd better be careful, because IList and List do hamiş behave the same way. Despite the similarity in name, and despite sharing an interface

Also, it casts IList to IList which özgü the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is derece guaranteed and emanet lead to brittle code.

Kendi koleksiyon sınıflarınızı oluştururken gene kullanılabilir şifre yazmanızı katkısızlar: C# CollectionBase kullanarak umumi koleksiyon fiillemlerini sineermiş bir temel sınıf oluşturabilirsiniz.

Your code is now broken, because int[] implements IList, but is of fixed size. The contract for ICollection (the base of IList) requires the code that uses it to check the IsReadOnly flag before attempting to add or remove items from the collection. The contract for List does hamiş.

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 birey 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 may hamiş ever need that option, but it's an argument. I think it's the entire argument for returning the interface instead of the concrete type. It's worth mentioning, but in this case it saf a serious flaw.

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed birli well. This is because a class adhering to IList guarantees a certain behavior that is hamiş guaranteed by a concrete type using List. Also having the power to do something like modify the default implementation of List on a class Implementing IList for say the .Add, .Remove or any other IList method gives the developer a lot

the method, it sevimli make a huge difference -- if they have an C# IList Nedir array C# IList Kullanımı and you're asking for a list, they have to change the array to a list or v.v. whenever calling the method, a total waste of time from both a programmer and performance POV.

Then later if you decide to convert the actual data store from a List to a Dictionary and expose the dictionary keys bey the actual value for the property (I have had to do exactly this before). Then consumers who have come to expect that their changes will be reflected inside of your class will no longer have that capability. That's a big C# IList Neden Kullanmalıyız mesele! If you expose the List birli an IEnumerable you hayat comfortably predict that your collection is hamiş being modified externally. That is one of the powers of exposing List as any C# IList Nerelerde Kullanılıyor of the above interfaces.

 

Benefit of using an Interface is that you get to implement 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 collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element.

Bu şekilde, Dog derslikı IAnimal interface’inin sözleşmesine uymuş evet. Aynı şekilde, diğer C# IList Nerelerde Kullanılıyor hayvan sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, bayağıdaki kodda bir Cat sınıfı teşhismladım ve IAnimal interface’ini uyguladım.
