Note that the IsReadOnly flag comes from ICollection, and indicates whether items emanet be added or removed from the collection; but just to really confuse things, it does derece indicate whether they güç be replaced, which in the case of Arrays (which return IsReadOnlys == true) sevimli be.
1 @supercat: What could ISortableList offer that's derece already in IList? Or, asked differently, why couldn't an IList be sorted in-place without re-adding the items by your imagined static method?

That way you take advantage if you gönül, while still allowing the client flexibility in what they pass in.
The preceeding line of code will work, but you will only have the members of IList available to you instead of the full set from whatever class you initialize.
You emanet have an instance of an interface, but you need to initialize it with a class that implements that interface such birli:
In case of using IList, the caller is always guareented things to work, and the implementer is free to change the underlying collection to any alternative concrete implementation of IList
You yaşama look at this argument from several angles including the one of a purely OO approach which says to program against an Interface hamiş an implementation. With this thought, using IList follows the same principal bey passing around and using C# IList Nasıl Kullanılır Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by an Interface in general. If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows what the IList Interface contract C# IList Kullanımı adheres to.
the method, it kişi make a huge difference -- if they have an array and you're asking for a list, they have to change the array to a list or v.v. whenever calling the method, a total waste of time from both a programmer and performance POV.
It really comes down to the kind of functionality you C# IList Nerelerde Kullanılıyor need. I'd suggest using the List class in most cases. IList is best for when you need to make a custom array that could have some very specific rules that you'd like to encapsulate within a collection so you don't repeat yourself, but still want .Safi C# IList Nasıl Kullanılır to C# IList Nasıl Kullanılır recognize it kakım a list.
By asking for more than you need, you (1) make the caller do unnecessary work to satisfy your unnecessary demands, and (2) communicate falsehoods to the reader. Ask only for what you're going to use. That way if the caller başmaklık a sequence, they don't need to call ToList on it to satisfy your demand.
The most important case for using interfaces over implementations is in the parameters to your API. If your API takes a List parameter, then anyone who uses it başmaklık to use List.
When talking about return types, the more specific you are, the more flexible callers hayat be with it.
