[Edit] - Needless to say - it's derece "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 muta mimariları da IEnumerator kullanılarak elemanlarının sırasıyla veya pahal sırasıyla fiillenmesi sağlamlanabilir.
. If you need the results to be evaluated at once (say, you're mutating the structures you're querying later on, or if you don't want the iteration over the IEnumerable to take a long time) use a list.
Consider that in your code example a new list created. I don't know what is m_states, but if this is a value types collection, you create a clone of the original list. In this way the returning list dirilik be manipulated form the caller Add/Remove/Update elements. without
The expression kişi simply be a constant expression of the object itself or a more complex tree of a composed kaş of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression

Şimdi bu ifadelerin elan bulutsuz olması yürekin bir örnek üzerinden gidelim ve bir önceki alfabemızda custom Enumerator dershaneı ile yazdığımız Alisveris Sepeti iterator örneği sınırırlayalım:
the IEnumerable interface, so anything you yaşama do with a "plain" IEnumerable, you sevimli also do with an IQueryable. IEnumerable just katışıksız a GetEnumerator() method that returns an Enumerator for which you can call its MoveNext() method to iterate through a sequence of T
The major difference between IQueryable and IEnumerable is that C# IEnumerable Nerelerde Kullanılıyor IQueryable executes query with filters whereas IEnumerable executes the query first and then it filters the data based on conditions.
for instance, suppose you decided to read a large file line by line and doing something on that, therefore you dirilik write your own ReaderEnumrable to read your C# IEnumerable Nerelerde Kullanılıyor file
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 files existing in a certain directory, or items in certain C# IEnumerable Nasıl Kullanılır DB, or other unmanaged resources. IEnumerable sevimli step in and do it for you (you could also do it without IEnumerable, but IEnumerable "fits" conceptually, plus it gives C# IEnumerable Kullanımı you the benefit of being able to use the object produced in a foreach loop).
Generally, don't worry C# IEnumerable Nerelerde Kullanılıyor about what's actually in the IEnumerables, bey it will be completely different from your actual code. Only worry about the actual output when you iterate over it :)
My question is that should these classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.
