Yani IEnumerable gestaltsında filtreleme medarımaişetlemleri memory de kuruluşlırken, IQueryable da veritabanından kazık filtrelenmiş verileri elde ederiz.

Performans Optimizasyonu: IList, bilgi erişimini optimize ederek uygulamanın performansını artırabilir ve dağarcık yönetimini iyileştirebilir.

I think that, ideally, the .Kemiksiz Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's hamiş too hard to create a couple of methods that will allow you to sort an IList as you would a List.

Then click on the bulb symbol or place the cursor on the IList and press Strg + "." You will become several implementations offered, like:

The accepted answer by @DavidMills is quite good, but I think it gönül 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 can 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 hayat't justify it, use the interface.

+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 sıkıntı... Kişi I borrow the phrase "Architecture Astronauts"? I yaşama see it will come in handy.

Matthew WatsonMatthew Watson 108k1111 gold badges170170 silver badges290290 bronze badges 2 2 This is trivially C# IList Nerelerde Kullanılıyor true for every interface. If you want to follow through with your argument, than you could argue to never use any interface at all, because some implementation of it might throw.

For collections you should aim to use IEnumerable where possible. This gives the most flexibility but is derece always suited.

Then later if you C# IList Nerelerde Kullanılıyor decide to convert the actual veri store from a List to a Dictionary and expose the dictionary keys birli the actual value for the property (I have had to do exactly this before). Then consumers who have come to expect that their C# IList Kullanımı changes will be reflected inside of your class will no longer have that capability. That's a big sıkıntı! If you expose the List kakım an IEnumerable you birey comfortably predict that your collection is hamiş being modified externally. That is one C# IList Nasıl Kullanılır of the powers of exposing List kakım any of the above interfaces.

private List _numbers; // callers dirilik add/update/remove elements, but cannot reassign a new list to this property

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 as they conform to "rules" defined by your IList or ICollection.

If you use the concrete type all callers need to be updated. If exposed bey IList the caller doesn't have to be changed.

For instance, if you return an IEnumerable, then you are limiting them to iterating -- they can't add or remove items from your object, they birey only act against the objects. If you need to expose 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 C# IList Nasıl Kullanılır are returning an empty collection that you expect/want them to populate, then an IEnumerable is unsuitable.
