I know there saf been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.

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

Interface’ler için elan bir tomar malumat peyda etmek isterseniz, adidaki kaynaklara çekmece atabilirsiniz:

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.

This will allow me to do generic processing on almost any array in the .Kupkuru framework, unless it uses IEnumerable and hamiş IList, which happens sometimes.

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 hayat 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.

So typically, your methods should accept and return interfaces for collections. This leaves your own implementation and your callers room to decide on the actual implementation as required.

additional advantage is that your code is safe from any changes to concrete class as you are subscribing C# IList Nasıl Kullanılır to only few of the methods of concrete class and those are the ones that are going to be there birli long birli the concrete class inherits from the interface you are using.
