Same principle as before, reversed. Offer the bare asgari that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

Also, it casts IList to IList which has the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is derece guaranteed and kişi lead to brittle code.

Hayat a unique position be deduced if pieces are replaced by checkers (güç see piece color but hamiş type)

Bandajlı listeler, hareketli data yapılarıdır. Bu sayede araya eleman ekleme, silme kadar aksiyonlemler daha zahmetsiz bir şekilde dokumalabilir. Bu hatmızda bağlamlı listelerin detaylarından bahsedeceğiz.

This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you emanet be sure that your list is derece going to be modified. When you are the person implementing the method and you say you accept an IEnumerable because all you need to do is iterate through that list.

+1 for all of us who hate it when a small app is loaded with interfaces and clicking on "find definition" takes us somewhere OTHER than the source of the mesele... Sevimli I borrow the phrase "Architecture Astronauts"? I sevimli see it will come in handy.

Ask those people what they'd like the methods to return. Your question is fundamentally "how do I know what software to write?" You know by getting to know what problems your customer başmaklık to solve, and writing code that solves their problems.

The idea is that you C# IList Nasıl Kullanılır hide the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.

If you sevimli 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 C# IList Nasıl Kullanılır more general.

This argument only works if you write your own implementation of IList from sratch (or at least without inheriting List)

List communicates "I need to C# IList Nerelerde Kullanılıyor get and takım the elements of this sequence in arbitrary order and I only accept lists; I do derece accept arrays."

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

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 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 depend on the fact that they C# IList Nerelerde Kullanılıyor gönül modify the list.
