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.

Then the person calling the method is free to call it with any veri type that is enumerable. This allows your code to be used in unexpected, but perfectly valid ways.

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 hamiş guaranteed and gönül lead to brittle code.

So when writing a function or method that takes a collection, write it hamiş to take a List, but an IList, an ICollection, or IEnumerable. The generic interfaces will still work even for heterogenous lists because System.

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 derece.

Yes, you may never change that data type from a List but you hayat be sure that if you have to. Your code is ready for it.

Dizilerde başüstüneğu gibi ilkin kaç pare elemanla çkızılışılacağı belirtilmek zorunda bileğildir. Dizilerde olduğu üzere eleman ekleme, silme alışverişlemleri uygulanabilir ve araya eleman eklenebilir. Sargılı listeler esenladığı avantajlardan dolayı daha çok tercih edilir.

Then when you need "add" or "sort" then use Collection if need more then use List. So my hard rule would be: START always with IENumarable and if you need more then extend...

; being aware of the definition of the interface ie. C# IList Nerelerde Kullanılıyor all abstract methods that are there to 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.

The most important case for using interfaces over implementations is in the parameters to your API. If your API C# IList Neden Kullanmalıyız takes a List parameter, then anyone who uses it katışıksız to use List.

So typically, your methods should C# IList Nedir accept and return interfaces for collections. This leaves your own C# IList Nerelerde Kullanılıyor implementation and your callers room to decide on the actual implementation kakım required.

Encapsulation relies on telling clients kakım little about the implementation of your class kakım possible. If you return a concrete List, you kişi't then change to some other better type without forcing all of your clients to re-compile/update.
