The above is an IList itself bey this is what seems to be the standard to use with nhibernate. Otherwise I might have returned IEnumberable back but derece sure. Still, I dirilik't figure out what the user would 100% need(that's where returning a concrete özgü an advantage over).

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?

I think that, ideally, the .Safi Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's not too hard to create a couple of methods that will allow you to sort an IList birli you would a List.

A List object allows you to create a list, add things to it, remove it, update it, index into it and etc. List is used whenever you just want a generic list where you specify object type in it and that's it.

Basically, I need to see some actual code examples of how using IList would have solved some sorun over just taking List into everything.

; being aware of the definition of the interface ie. all abstract methods that are there to be C# IList Neden Kullanmalıyız implemented by any class inheriting the interface. so if some one makes a huge class of his own with several methods besides C# IList Nasıl Kullanılır 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 a subclass (in this case the interface) and assign the concrete class object to it.

If you can consider your method, determine that you probably won't be changing the return collection type, then it is probably safe to return a more exact type. If you aren't sure, or are afraid that if you change it in future you'll be breaking other people's code, then go more general.

It is like this other question. The other question shares a lot of common ground, but is arguably hamiş a true duplicate. In either case C# IList Nedir though, this is not opinion-based. What may have happened is that the closer might have just looked at this question's title, without reading the question itself. The body is objective.

rajeshrajesh 39133 silver badges22 bronze badges 1 8 Excellent, clear answer, which I marked birli helpful. However, I would add that for most developers, most of the time, the tiny difference in yetişek size and performance is hamiş worth worrying about: if in doubt, just use a List.

When talking about return types, the more specific you are, the more flexible callers can be with it.

It doesn't affect C# IList Nerelerde Kullanılıyor the signature of the method, and is grup in stone at compile time. You should instead be helping him get over his confusion about declaring his local like IList foo = new List - this is where his confusion clearly lies.
