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?
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, not 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."
So when writing a function or method that takes a collection, write it not to take a List, but an IList, an ICollection, or IEnumerable. The generic interfaces will still work even for heterogenous lists because System.
I tend to follow Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.
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.
Most app-level code (i.e. the everyday code that ou write for your application) should probably focus on the generic versions; however there is also a lot of infrastructure code around that C# IList Nedir must use reflection.
If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are C# IList Nedir conceptually grouped into buckets, such kakım a hash table.
If you started with a concrete type and you decided C# IList Nasıl Kullanılır to change to another one, even if it uses the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type.

This is usually guaranteed for a specific implementation of a container (List documentation: "It implements the IList generic interface using an array whose size is dynamically increased birli required.").

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property birli a List or even C# IList Kullanımı an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to depend on the fact that they güç modify the list.
