The above is an IList itself bey this is what seems to be the standard to use with nhibernate. Otherwise I might have returned IEnumberable back but derece sure. Still, I birey't figure out what the user would 100% need(that's where returning a concrete saf an advantage over).

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.

Interface’ler üzerine henüz aşkın bili olmak isterseniz, adidaki kaynaklara hane atabilirsiniz:

Kendi derme sınıflarınızı oluştururken tekrar kullanılabilir şifre yazmanızı katkısızlar: C# CollectionBase kullanarak umumi derlem fiillemlerini bâtınaziz bir esas klas oluşturabilirsiniz.

The accepted answer by @DavidMills is quite good, but I think it birey be improved upon. For one, there is no need to define the ComparisonComparer class when the framework already includes a static method Comparer.Create(Comparison). This method güç be used to create an IComparison on the fly.

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 birey be sure that your list is hamiş going to be modified. C# IList Nasıl Kullanılır When you are the person implementing the method and you say you accept an IEnumerable because all you need to C# IList Neden Kullanmalıyız do is iterate through that list.

The class name List may be changed in next .kupkuru framework but the interface is never going to change bey interface is contract.

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 saf to solve, and writing code that solves their problems.

If you are exposing your class through a library that others will use, you generally want to expose it via interfaces rather than concrete implementations.

You would because defining an IList or an ICollection would open up for C# IList Neden Kullanmalıyız other implementations of your interfaces.

By asking for more than you C# IList Nerelerde Kullanılıyor need, you (1) make the caller do unnecessary work to satisfy your unnecessary demands, and (2) communicate falsehoods to the reader. Ask only for what you're going to use. That way if the caller katışıksız C# IList Neden Kullanmalıyız a sequence, they don't need to call ToList on it to satisfy your demand.

You might want to have an IOrderRepository that defines a collection of orders in either a IList or ICollection. You could then have different kinds of implementations to provide a list of orders kakım long birli they conform to "rules" defined by your IList or ICollection.

In collections of contiguous elements, such kakım lists, the elements that follow the insertion point move down to accommodate the new element.

There is a complication though that dynamic gönül't see explicit implementations, so something sevimli implement IList and IList-of-T and yet still be completely unusable from dynamic.
