"Are there any simple groups that appear bey zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?
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.
The less popular answer is programmers like to pretend their software is going to be re-used the world over, when infact the majority of projects will be maintained by a small amount of people and however birçok interface-related soundbites are, you're deluding yourself.
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.

You emanet have an instance of an interface, but you need to initialize it with a class that implements that interface such kakım:

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 derece guaranteed by a concrete type using List. Also having the power C# IList Nasıl Kullanılır 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
; being aware of the definition of the interface ie. all abstract methods that are there to be implemented C# IList Kullanımı 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 C# IList Nerelerde Kullanılıyor a subclass (in this case the interface) and assign the concrete class object to it.
class Kisi string ad; string soyad; public string Ad get return ad; seki ad = value; public string Soyad get return soyad; seki soyad = value;

Returning a read-only interface such kakım IEnumerable is often the way to go for veri-retrieval methods. Your consumer kişi project it into a richer type bey-needed.
You sevimli pass a plain array to something which accepts an IList parameter, and then you güç call IList.Add() and will receive a runtime exception:
The other general reason for using interfaces is to expose the asgari amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a data object that implements IList.
