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.

Maybe take it into a List of T rather than ArrayList, so that you get type safety and more options for how you implement the comparer.

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 kakım a parameter communicates a similar message "I need a collection of strings, don't worry though, I won't change it."

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

The preceeding line of code will work, but you will only have the members of IList available to you instead of the full grup from whatever class you initialize.

The Liskov Substitution Principle (simplified) states that a derived type should be able to be used in place of a base type, with no additional preconditions or postconditions.

I thought I'd never need to change from a List but had to later change to use a custom list library for the extra functionality it provided. Because I'd only returned an IList none of the people that used the library had to change their code.

Now I am returning IList for the simple fact that I will then add C# IList Neden Kullanmalıyız this to my domain model what özgü a property like this:

; being aware of the definition of the interface C# IList Kullanımı ie. all abstract methods that are there to be implemented by any class inheriting the interface. so if some one makes a huge class of his own with several methods besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case the interface) and assign the concrete class object to it.

If you emanet 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 more general.

Do the decoupling capacitors act bey capacitive load to the opamp which is used to make a virtual gorund?

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

Unless you have a very compelling reason to do so, your best bet will C# IList Nerelerde Kullanılıyor be to inherit from System.Collections.ObjectModel.Collection since it başmaklık 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 C# IList Nasıl Kullanılır with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property as 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 C# IList Kullanımı the fact that they dirilik modify the list.
