Arraylist: Dinamik boyutludur, eleman ekleme/silme hizmetlemleri elan kolaydır ve farklı done türlerini saklayabilir.

1 @supercat: What could ISortableList offer that's hamiş already in IList? Or, asked differently, why couldn't an IList be sorted in-place without re-adding the items by your imagined static method?

Elemanların Sıralı Yapkaloriı Müdafaa: IList, elemanların eklenme sırasını korur. Bu özellik, muta yapkaloriın sıralı olmasını ve yetişekın beklentilerine akla yatkın çhileışmasını katkısızlar.

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.

Convert your IList into List or some other generic collection and then you sevimli easily query/sort it using System.Linq namespace (it will supply bunch of extension methods)

In most cases, if you are using a List and you think you could use a narrower interface instead - why hamiş IEnumerable? This is often a better fit if you don't need to add items. If you need to add to the collection, use the concrete type, List.

If you code your own class implementing the IList interface, make sure you also implement the non-generic C# IList Nasıl Kullanılır IList interface, or the code will fail with a class cast exception.

I know that C# IList Kullanımı IList is the interface and List is the concrete type but I still don't know when C# IList Neden Kullanmalıyız to use each one. What I'm doing now is if I don't need the Sort or FindAll methods I use the interface. Am I right? Is there a better way to decide when to use the interface or the concrete type?

Bu örnekte, Student isminde bir C# IList Nedir klas ve StudentCollection adında CollectionBase dershaneından türeyen özel bir derlem klası oluşturduk.

for your return types. C# IList Nerelerde Kullanılıyor This gives your callers the most flexibility in passing in types to your methods and the most opportunities to cast/reuse the return values.

So I have been playing around with some of my methods on how to do this. I am still hamiş sure about the return type(if I should make it more concrete or an interface).
