The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list. This code is part of a larger example for the IList interface.

Bir dahaki sefere değerlendirme yaptığımda kullanılmak üzere kademı, elektronik posta adresimi ve web şehir adresimi bu tarayıcıevet kaydet.

Diyelim ki formunuzdaki textboxları listenize doldurdunuz yalnızca Text’i boş olan textboxları bulmanız gerekiyor. Bunun bâtınin List u kullanmanız gerekir. Mafevkda anlattığımız örneği yalınç olarak yapacak olursak;

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.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

You may not 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 katışıksız 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 C# IList Nerelerde Kullanılıyor is not 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 C# IList Neden Kullanmalıyız .Add, .Remove or any other IList method gives the developer a lot

If the parameter type is IList, then the caller has much C# IList Neden Kullanmalıyız more freedom, and kişi use classes you never heard about, which may not even have existed when your code was written.

Modülerlik: C# IList Nerelerde Kullanılıyor Yazılım projelerinde modüler bir yaklaşım sunarak harf geneını azaltır ve hizmetı kolaylaştırır.

If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked kakım helpful. However, I would add that for most developers, most of the time, the tiny difference in program size and performance is not worth worrying about: if in doubt, just use a List.

Unless you have a very compelling reason to do so, your best bet will be to inherit from System.Collections.ObjectModel.Collection since it saf everything you need.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they kişi't add or remove items from your object, they kişi only act C# IList Kullanımı against the objects. If you need to expose a collection outside of a class, but don't want to let the caller change the collection, this is one way of doing it. On the other hand, if you are returning an empty collection that you expect/want them to populate, then an IEnumerable is unsuitable.
