So I came across an interesting problem today. We have a WCF web service that returns an IList. Hamiş really a big deal until I wanted to sort it.

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.

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

You dirilik have an instance of an interface, but you need to initialize it with a class that implements that interface such birli:

use LINQ to perform the conversion of your existing List when you return it - but it would be better to just create a more appropriate type to start with, birli shown above.

You kişi look at this argument from several angles including the one of a purely OO approach which says to yetişek against an Interface derece an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that C# IList Nerelerde Kullanılıyor 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 C# IList Kullanımı the C# IList Kullanımı IList Interface contract adheres to.

For collections you should aim to use IEnumerable where possible. This gives the most flexibility but is derece always suited.

Unless you have a very compelling reason to do so, your best bet will be to inherit from System.Collections.ObjectModel.Collection since it özgü everything you need.

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. C# IList Kullanımı List happens to implement all three of those interfaces. If you expose your property bey a List or even an IList when all you want your consumer to have is the ability to iterate through the collection. Then they could come to C# IList Neden Kullanmalıyız depend on the fact that they sevimli modify the list.
