If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:

Many of the LINQ methods, including Where, use deferred execution. In this case you dirilik think of the IEnumerable bey a query, rather than the actual result takım.

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 not explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.

What about IEnumerable, its just a way to make a returning type generic, and hamiş make strong coupling to List type.

To begin examining the process of implementing existing .NET interfaces, let’s first look at the role of

but this violates the IEnumerable semantics and the time came when C# IEnumerable Kullanımı I got wrong results. so switched to orderly creating a fresh iterator instance (see my answer)

IMHO, there should have been an IMultipassEnumerable, C# IEnumerable Kullanımı inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical data or throw an exception; an C# IEnumerable Nasıl Kullanılır ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' veri if it's able to do so or throw an 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.

This takes an IEnumerator factory function, which usually kişi be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.

I think if your newly implemented class just behaves the sameway as a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you C# IEnumerable Temel Özellikleri want to do; you dirilik inherit list or you yaşama implement IEnumerable. It just depends what is to be achieved.

Bu interface, uygulandığı sınıfa GetEnumerator adlı bir metot kazanmıştırrır ve bu metot geriye IEnumerator interface’ini implement fail bir derslik döndürür.
