I think that, ideally, the .Kupkuru 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 hamiş too hard to create a couple of methods that will allow you to sort an IList bey you would a List.

So when writing a function or method that takes a collection, write it hamiş to take a List, but an IList, an ICollection, or IEnumerable. The generic interfaces will still work even for heterogenous lists because System.

IList is a interface and doesn't have any implementation, so the performance of IList depending the class it implements

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you emanet't justify it, use the interface.

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. It's worth mentioning, but in this case it özgü a serious flaw.

However using a concrete implementation and List on a class that changes, could cause the calling code to need to be changed birli well. C# IList Kullanımı This is because a class adhering to IList guarantees a certain behavior that is not guaranteed by a concrete type using List. Also having the power to do something like modify the default implementation of List on a class Implementing IList for say the .Add, C# IList Neden Kullanmalıyız .Remove or any other IList method gives the developer a lot

If C# IList Nedir the parameter type is IList, then the caller has much more freedom, and yaşama use classes you never heard about, which may derece even have existed when your code was written.

If you code your own class implementing the C# IList Neden Kullanmalıyız IList interface, make sure you also implement the non-generic IList interface, or the code will fail with a class cast exception.

It is like this other question. The other C# IList Kullanımı question shares a lot of common ground, but is arguably hamiş a true duplicate. In either case 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.

Returning a read-only interface such birli IEnumerable is often the way to go for data-retrieval methods. Your consumer gönül project it into a richer type bey-needed.

If you're just enumerating over the values, you should be using IEnumerable. Every type of datatype that dirilik hold more than one value implements IEnumerable (or should) and makes your method hugely flexible.

The other general reason for using interfaces is to expose the asgari amount of knowledge necessary to the user of an object. Consider the (contrived) case where I have a veri object that implements IList.
