Arraylist: Hareketli boyutludur, eleman ekleme/silme sorunlemleri elan kolaydır ve farklı data türlerini saklayabilir.

I don't totally disagree with the sentiment of over-architecture being a real sorun. However I think that especially in the case of collections that interfaces really shine.

Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does derece contain an array, so all of a sudden, we had almost no use of the large object heap.

David MillsDavid Mills 2,41511 gold badge2323 silver badges2525 bronze badges 6 2 The right approach really would have been to offer an ISortableList interface (with methods to sort a portion of the list using some particular comparer), have List implement it, and have a static method which could sort any IList by checking whether it implemented ISortableList and, if not, copying it to an array, sorting that, clearing the IList, and re-adding the items.

Use whatever you want. It's your method. You're the only one who gets to see the internal implementation details of the method.

The speed difference is sufficiently great that in many cases it may be faster to copy a list to an array, sort the array, and copy the list back, than to try C# IList Nerelerde Kullanılıyor to have a C# IList Kullanımı sort routine process the list in place.

Dizilerde evetğu kabilinden ilkin kaç pare elemanla çkızılışılacağı belirtilmek zorunda değildir. Dizilerde olduğu üzere eleman ekleme, silme ustalıklemleri uygulanabilir ve araya eleman eklenebilir. Bağlamlı listeler katkısızladığı avantajlardan dolayı henüz çok yeğleme C# IList Kullanımı edilir.

If you specify your methods to return an interface that means you are free to change the exact implementation later on without the consuming method ever knowing.

If you started with a concrete type and you decided to change to another one, even if it uses the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type. Share Improve this answer Follow

List implements those nine methods (hamiş including extension methods), on ferde of that it katışıksız about 41 public methods, which weighs in your consideration of which one to use in your application.

IList is not a class; it's an interface that classes sevimli implement. The interface itself is just a contract between the consumer of the class and the class itself. This line of code will work:

Brad LeachBrad Leach 17k1818 C# IList Kullanımı gold badges7373 silver badges8888 bronze badges 1 3 It will create a new enumerable, which may hamiş be desirable in some scenarios. You cannot sort an IList in-place through the interface except by using ArrayList.Adapter method in my knowledge.

When talking about return types, the more specific you are, the more flexible callers birey be with it.

There is a complication though that dynamic hayat't see explicit implementations, so something yaşama implement IList and IList-of-T and C# IList Nasıl Kullanılır yet still be completely unusable from dynamic.
