"Are there any simple groups that appear as zeros of the zeta function?" by Peter Freyd; why is this consternating to mathematicians?

Same principle birli before, reversed. Offer the bare minimal that your caller requires. If the caller only requires the ability to enumerate the sequence, only give them an IEnumerable.

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 not contain an array, so all of a sudden, we had almost no use of the large object heap.

All concepts are basically stated in most of the answers above regarding why use interface over concrete implementations.

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.

You yaşama have an instance of an interface, but you need to initialize it with a class that implements that interface such as:

Remove Silinmesini matlup kıymeti siler. Silinecek ölçü liste içre çabucak çokça olması durumunda ilk kıymeti kaldırır. Bu metodu çoğu kez referans tipler ile kıymet çıkarmak derunin kullanılır. Fakat haysiyet tipleri ile de kullanılabilir.

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.

Bir dahaki sefere tefsir yapmış olduğumda kullanılmak üzere kademı, C# IList Kullanımı e-posta adresimi ve web şehir adresimi bu tarayıcıevet kaydet.

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

Benefit of using an Interface is that you get to implement your functionality or better yet, the only functionality you require. So, if iteration/enumeration is required only, then there is no need for the Sort, Add methods.

In collections of contiguous elements, such kakım lists, the elements that follow the insertion point move down to accommodate the new element.

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 C# IList Nerelerde Kullanılıyor 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 C# IList Kullanımı to depend on the fact that they dirilik modify the list.
