[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.

An Enumerable is a class that emanet give you Enumerators. It saf a method called GetEnumerator which gives you an Enumerator that looks at its items. When you write a foreach loop in C#, the code that it generates calls GetEnumerator to create the Enumerator used by the loop.

What I do is make a class that implements both IEnumerator and IEnumerable. Make GetEnumerator() return itself and you kişi iterate it like düzgülü.

// but this throws an exception, because the pointer or link to the // database namely the DbContext called MyEntities no longer exists.

This way you have possibility to do many things with that query without touching the veri (in this case data in the list). List method takes the prepared query and executes it against the source of veri.

Else use an IEnumerable. The default should be to use the on-demand evaluation in the second example, C# IStructuralComparable nedir kakım that generally uses less memory, unless there is a specific reason to store the results in a list.

This works for read-only access to a collection that implements that IEnumerable kişi be used with a foreach statement.

It is cleaner, your users don't get a list where they shouldn't (they could cast it to a Listafter all) and you don't need to create a Listobject.

There's also the issues of C# IStructuralComparable Kullanımı deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and can perform all kinds of computations before and after. And again, this happens one-by-one, so you don't have to hold C# IEnumerable Kullanımı all the collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you run the foreach loop).

Bu interface, uygulandığı sınıfa GetEnumerator C# IEnumerable Kullanımı adlı bir metot kazanmıştırrır ve bu metot geriye IEnumerator interface’ini implement fail bir klas döndürür.

IEnumerable interface’i ile bir dershane itere edilebilir hale getiriliyor, bu işlem zarfında C# IEnumerable Nerelerde Kullanılıyor GetEnumerator metodu sınıfa implement ediliyordu. IEnumerator interface’i ise iterasyon özelliği kazandıracak ve iterasyon kârleminde kullanılacak elemanları ve özellikleri çitndırmaktadır.
