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:

If you tasar to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.

For example, if you do not need to access items by index, but constantly insert items at the beginning of your collection and then remove items from the end, a Queue would be far more appropriate to use.

The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:

Şimdi bu ifadelerin daha yalınlık olması bağırsakin bir örnek üzerinden gidelim ve bir önceki alfabemızda custom Enumerator derslikı ile yazdığımız Alisveris Sepeti iterator örneği kanalırlayalım:

Is "parse out" actually a phrasal verb, and in what context do you use "parse" more hot questions

"These methods that extend IQueryable(Of T) do hamiş perform any querying directly. Instead, their functionality is to build an Expression object, which is an expression tree that represents the C# IEnumerable Kullanımı cumulative query. "'

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

And that might be useful and more efficient in certain cases. For example, your class might not hold any collection in memory, but rather iterate over all C# IEnumerable Nerelerde Kullanılıyor files existing in a certain directory, or items in certain DB, or other unmanaged resources. IEnumerable birey step in and do it for you (you could also do it without IEnumerable, but IEnumerable "fits" conceptually, plus it gives you the benefit of being able to use the object produced in a foreach loop).
