From this it follows that your method implementation hayat represent its local variables however you wish. The implementation details are not exposed. Leaving you free to change your code to something better without affecting the people calling your code.

Interface’ler için daha şu denli fen peyda etmek isterseniz, hordaki kaynaklara dide atabilirsiniz:

Sıfır madun limitına iye biricik boyutlu diziler otomatik olarak uygular IList. Bu, diziler ve öbür koleksiyon türleri beyninde yineleme tutmak için aynı kodu kullanabilen umumi yöntemler oluşturmanıza imkân tanır.

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 birey be used to create an IComparison on the fly.

I would turn the question around a bit, instead of justifying why you should use the interface over the concrete implementation, try to justify why you would use the concrete implementation rather than the interface. If you yaşama't justify it, use the interface.

Object emanet be a T too. Doing C# IList Neden Kullanmalıyız this will save you headache if you decide to use a Stack or some other data structure further down the road. If all you need to do in the function is foreach through it, IEnumerable is really all you should be asking for.

 

And, if you don't even need everything in IList you birey always use IEnumerable too. With modern compilers and processors, I don't think there is really any speed difference, so this is more just a matter C# IList Nerelerde Kullanılıyor of style.

The Cast function is just a reimplementation of the extension method that comes with 3.5 written as a olağan static method. It is quite ugly and verbose unfortunately.

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

List communicates "I need to get and takım the elements of this sequence in arbitrary order and I only accept lists; I do not accept arrays."

I C# IList Kullanımı have two ILists of the same type returned by NHibernate and have emerged the two IList into one, hence the need for sorting.

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 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 the fact that they can modify the list.
