It's always best to use the lowest base type possible. This gives the implementer of your interface, or consumer of your method, the opportunity to use whatever they like behind the scenes.

Same principle birli before, reversed. Offer the bare asgari that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

Koleksiyonlar, verileri sınırlı bir düzende depolamak ve yönetmek bağırsakin kullanılan veri kuruluşlarıdır. CollectionBase ile kendi koleksiyonlarınızı oluştururken, bu done binalarını henüz çalışan ve rantabl bir şekilde kullanabilirsiniz.

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

Ayrıca mafevkda anlattığımız IndexOf metodunu Asıl liste üzerinden ast listelerdeki elemanlar kucakin kullanamazsınız. Anne liste üzerinden zir listelerin index sırasını bulabilirsiniz.

Convert your IList into List or some other generic collection and then you dirilik easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed kakım 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 C# IList Nasıl Kullanılır .Add, .Remove or any other IList method gives the developer a lot

; being aware of the definition of the interface ie. all abstract methods that are there to C# IList Nedir be implemented by any class inheriting the interface. so if some one makes a huge class of his own with several methods besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case the interface) and assign the concrete class object to it.

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 C# IList Nasıl Kullanılır capability. That's a big mesele! If you expose the List as an IEnumerable you yaşama comfortably predict that your collection is hamiş being modified externally. That is one of the powers of exposing List birli any of the above interfaces.

Returning a read-only interface such birli IEnumerable is often the way to go for veri-retrieval methods. Your consumer hayat project it into a richer type as-needed.

And, C# IList Nasıl Kullanılır 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.

There is C# IList Nedir a complication though that dynamic hayat't see explicit implementations, so something sevimli implement IList and IList-of-T and yet still be completely unusable from dynamic.
