5 Basit Teknikleri için C# IEnumerable Nerelerde Kullanılıyor

[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.

Queue ve Stack: Queue ve Stack üzere done örgüları da IEnumerator kullanılarak elemanlarının sırasıyla veya pahal sırasıyla sorunlenmesi esenlanabilir.

A. We iterate the list in different way, foreach kişi be used for IEnumerable and while loop for IEnumerator.

An IEnumerator is a thing that can enumerate: it başmaklık the Current property and the MoveNext and Reset methods (which in .Kupkuru code you probably won't call explicitly, though you could).

IEnumerator is a class that enumerates collections. A class that implements IEnumerable returns an IEnumerator. A class that implements IEnumerator özgü custom enumeration logic.

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

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

Your linq expression returns an enumeration, and by C# IEnumerable Nasıl Kullanılır default the expression executes when you iterate through using the foreach. An IEnumerable linq statement executes when you iterate C# IEnumerable Nerelerde Kullanılıyor the foreach, but you hayat force it to iterate sooner using .ToList().

List, on the other hand, is a C# IEnumerable Nerelerde Kullanılıyor specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, this may be a very good way to store your values that you expose via IEnumerable, but a List is derece always appropriate.

And that might be useful and more efficient in certain cases. For example, your class might hamiş hold any collection in memory, but rather iterate over all files existing in a certain directory, or items in certain DB, or other unmanaged resources. IEnumerable hayat 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).
