We needed the list indexer infrequently, so the inefficiency was not a sorun. If it had been, we could have provided some other implementation of IList, perhaps birli a collection of small-enough arrays, that would have been more efficiently indexable while also avoiding large objects.

Lütfen adidaki kutuya şikayetinizin detaylarını edebiyat. Şikayetinizi bileğerlendirildikten sonra size bilgi vereceğiz.

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.

Basically, I need to see some actual code examples of how using IList would have solved some sorun over just taking List into everything.

This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you sevimli be sure that your list is hamiş going to be modified. When you are the person implementing the method and you say you accept an IEnumerable because all you need to do is iterate through that list.

use LINQ to perform the conversion of your existing List when you C# IList Nerelerde Kullanılıyor return it - but it would be better to just create a more appropriate type to start with, birli shown above.

You yaşama look at this argument from several angles including the one of a purely OO approach which says to izlence against an Interface derece an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you define from scratch. I also believe in the scalability and C# IList Nerelerde Kullanılıyor flexibility factors provided by an Interface in general. If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows what the IList C# IList Kullanımı Interface contract adheres to.

The idea is that you hide C# IList Nasıl Kullanılır the implementation details from the user, and instead provide them with a stable interface. This is to reduce dependency on details that might change in the future.

It is like this other question. The other question shares a lot of common ground, but is arguably hamiş a true duplicate. In either case though, this is hamiş opinion-based.
