Note that the IsReadOnly flag comes from ICollection, and indicates whether items gönül be added or removed from the collection; but just to really confuse things, it does derece indicate whether they hayat be replaced, which in the case of Arrays (which return IsReadOnlys == true) kişi be.

IList is an interface so you güç inherit another class and still implement IList while inheriting List prevents you to do so.

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 bey a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

Of course that only need apply to methods that are externally visible (i.e. public methods). I personally use interfaces even in C# IList Nedir internal code, but as you are able to change all the code yourself if you make breaking changes it's not strictly necessary.

In this case you could pass in any class which implements the IList interface. If you used List instead, only a List instance could be passed in.
