Note that the IsReadOnly flag comes from ICollection, and indicates whether items birey be added or removed from the collection; but just to really confuse things, it does derece indicate whether they birey be replaced, which in the case of Arrays (which return IsReadOnlys == true) güç be.
Today, you almost always use IList, the primary reason for IList to still be around is for reasons of backwards compatibility.
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 nice interface-related soundbites are, you're deluding yourself.
The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list.
In addition to the older code that doesn't know about generics, there are also a lot of cases where you know you have a list
The Liskov Substitution Principle (simplified) states that a derived type should be able to be used in place of a base type, with no C# IList Nerelerde Kullanılıyor additional preconditions or postconditions.
You may hamiş 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. C# IList Nedir It's worth mentioning, but in this case it has a serious flaw.
Now I am returning IList for the simple fact that I will then add this to my domain mostra what saf a property like this:
Anahtar değerleri C# IList Nasıl Kullanılır belirtilen bir mukabillaştırıcı kullanılarak kontralaştırılır ve her grubun öğeleri belirtilen bir meselelev kullanılarak yansıtılır.

Bir ahir elementin varlığını sınayan MoveNext ve meri elementi veren GetCurrent metodlarına sahiptir.
Then I looked in my view(mvc) and found that I actually needed the count method kakım I needed to use a for loop. So in my own application I under estimated C# IList Kullanımı what I actually needed how do you anticipate what someone else will need or hamiş need.
If you use a concrete implementation of list, another implementation of the same list will derece C# IList Nerelerde Kullanılıyor be supported by your code.
If you had used IList in the rest of the app you could extend List with your own custom class and still be able to pass that around without refactoring.
