@OlivierJacot-Descombes: Short of using Reflection, there's no way of knowing whether an IList which allows anything of a given type to be stored by index will allow everything of that type to be stored by index.
Anything in .Kemiksiz that you güç iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you yaşama make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).
IEnumerable interface’i sayesinde bir dershane itere edilebilir özellik kazanmaktadır. Evet bir sınıfın itere edilebilirlik özellik kazanması neydi?
The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are hamiş explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.
The expression hayat simply be a constant expression of the object itself or a more complex tree of a composed seki of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression
B. IEnumerator birey C# IEnumerable Temel Özellikleri remember the current index when we pass from one method to another (it start working with current index) but IEnumerable gönül't remember the index and it reset the index to beginning. More in this video
List: List derslikı, hareketli boyutlarda sıralı koleksiyonlar bağırsakin kullanılır ve bu tür koleksiyonlarda elemanları gezinmek sinein IEnumerator tasarrufı yaygındır.

Bu alanda veya başka bir alanda, benim ve sair yardımcı insanların paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm şeşna girmeniz mazmunına gelmemektedir.
There are many cases (such bey an infinite list or a very large list) where IEnumerable cannot be transformed to a List. The most obvious examples are all the prime numbers, all the users of facebook with their details, or all the items on ebay. The difference is that "List" objects are stored "right here and right C# IEnumerable Nedir now", whereas "IEnumerable" objects work "just one at a time".
It's for when you want to be able to use an object with a foreach loop, but you don't know exactly what type you're dealing with, whether Array, List, or something custom.
Expression trees are a very important construct in C# and on the C# IEnumerable Nedir .Kupkuru platform. (They are important in general, but C# makes them very useful.) To better understand the difference, I recommend reading about the differences between expressions
If you C# IEnumerable Nasıl Kullanılır create an IEnumerable, then all rows will be pulled into memory bey objects before running the query.
In C# IEnumerable Nedir addition to all the answers posted above, here is my two cents. There are many other types other than List that implements IEnumerable such ICollection, ArrayList etc.
