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

Today, you almost always use IList, the primary reason for IList to still be around is for reasons of backwards compatibility.

Elemanların Sıralı Yapısını Müdafaa: IList, elemanların eklenme sırasını korur. Bu özellik, done yapısının sıralı olmasını ve yetişekın beklentilerine reva çallıkışmasını esenlar.

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.

Use whatever you want. It's your method. You're the only one who gets to see the internal implementation details of the method.

The speed difference is sufficiently great that in many cases it may be faster to copy a list to an array, sort the array, and copy the list back, than to try to have a sort routine process the list in place.

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

This example also tells you that there may be situations when you need to specify the implementation, derece the interface, in the argument list: In this example, whenever you require a particular access performance characteristic.

It really comes down to the kind of functionality you 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 C# IList Nedir a collection so you don't repeat yourself, but still want .NET to recognize it as a list.

If you're working within a single method (or even in a single class or assembly in some cases) and no one outside is going to see what you're doing, use the fullness of a List. But if you're interacting C# IList Nerelerde Kullanılıyor with outside code, like when you're returning a list from a method, C# IList Neden Kullanmalıyız then you only want to declare the interface without necessarily tying yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

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

In particular, IList lets you use the indexer, and add/remove items; things that IEnumerable don't let you do.

would I run into problems with this? Since could they derece pass in an array(that saf C# IList Nerelerde Kullanılıyor a fixed size)? Would it be better maybe for a concrete List?
