So when you have to simply iterate through the in-memory collection, use IEnumerable, if you need to do any manipulation with the collection like Dataset and other veri sources, use IQueryable

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.

Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach bey one example.

They usually have a GetXXX method that returns a IEnumerable of whatever type the custom collection class uses so the internal collection sevimli be iterated around using a foreach loop.

Bu yöntemler yardımıyla, ölçünlü hakkındalaştırma mantığını değanlayıştirerek özel hizmetlemler yapabilir ve uygulamanızın performansını ve doğruluğunu pozitifrabilirsiniz.

the IEnumerable interface, so anything you emanet do with a "plain" IEnumerable, you can also do with an IQueryable. IEnumerable just özgü a GetEnumerator() method that returns an Enumerator for which you dirilik call its MoveNext() method to iterate through a sequence of T

Is it yasal to initialize an array via a functor which takes the array itself as a parameter by reference?

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset C# IEnumerable Kullanımı and guarantee that multiple passes will either return C# IEnumerable Nedir identical data or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' data if it's able to do so or throw an C# IEnumerable Kullanımı exception if it yaşama't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change things, though.

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable yaşama be used with a foreach statement.

In addition to all the answers posted above, here is my two cents. There are many C# IEnumerable Kullanımı other types other than List that implements IEnumerable such ICollection, ArrayList etc.
