I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method bey well as casting to a List but none of these seemed overly elegant.

What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?

Say I have a function that returns IEnumerable, inside the function I may use a List for an internal backing store to generate my collection, but I only want callers to enumerate it's contents, derece add or remove. Accepting an interface as a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

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 not.

so its safety for you and freedom to the coder who is writing concrete implementation to change or add more functionality to his concrete class.

use LINQ to perform the conversion of your existing List when you return it - but it would be better to just create a more appropriate type C# IList Nasıl Kullanılır to start with, kakım shown above.

If you want to follow through with your argument, than you could argue to never use any interface at all, because some implementation of C# IList Nasıl Kullanılır it might throw.

Whether you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created -- this is an API design decision, and there's no hard and fast rule. You have to weigh their ability to make full use of the object against their ability to easily use a portion of the objects functionality (and of course whether you WANT them to be making full use of the object).

You cannot sort an IList in-place through the interface except by using ArrayList.Adapter method in my knowledge.

You emanet pass a plain array to something which accepts an IList parameter, and then you can call IList.Add() and will receive a runtime exception:

Ancak list kullanımında kapasite belirtilmez kullanıcak veriler C# IList Neden Kullanmalıyız sınırlı ise örneğin haftanın günleri ise bunları diziye tanılamamlayabiliriz ancak kullanılacak veriler makine plakası,telefon numarası gibi nüshası meçhulat veriler kullanıcak ise mutlaka list olarak saklanmalıdır.Şimdi C#’ta list tasarrufı midein örneğimize bakalım.
