Bu şekilde listelerin birbirini point etmesi ve bandajlı listenin elemanlarına kıymetiharbiye verilmesi sağlanmaktadır.
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 not guaranteed and gönül lead to brittle code.
Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
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.
List is a specific implementation of IList, which is a container that güç be addressed the same way kakım a linear array T[] using an integer index. When you specify IList as the type of the method's argument, you only specify that you need certain capabilities of the container. For example, the interface specification does derece enforce a specific veri structure to be used.
You hayat look at this argument from several angles including the one of a purely OO approach which says to yetişek against an C# IList Kullanımı Interface derece an implementation. With this thought, using IList follows the same principal bey passing around and using Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by an Interface in general. C# IList Nedir If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows C# IList Neden Kullanmalıyız what the IList Interface contract adheres to.
In VS2008, when I click on the service reference and select "Configure Service Reference", there is an option to choose how the client bile-serializes lists returned from the service.
Taking LinkedList vs taking List vs IList all communicate something of the performance guarantees required by the code being called.
By asking for more than you 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 başmaklık a sequence, they don't need to call ToList on it to satisfy your demand.

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.
For instance, if you return an IEnumerable, then you are limiting them to iterating -- they dirilik't add or remove items from your object, they can only act against the objects. If you need to expose C# IList Nasıl Kullanılır a collection outside of a class, but don't want to let the caller change the collection, this is one way of doing it. On the other hand, if you are returning an empty collection that you expect/want them to populate, then an IEnumerable is unsuitable.
