Queue ve Stack: Queue ve Stack gibi done yapıları da IEnumerator kullanılarak elemanlarının sırasıyla yahut münasebetsiz sırasıyla işçiliklenmesi sağlanabilir.

This where filter is executed on the client side where the IEnumerable code is. In other words all the data is fetched from the database and then at the client its scans and gets the record with EmpId is 2.

Analogy: Imagine you are a detective on an aeroplane . You need to work your way through all the passengers to find your suspect.

Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach bey one example.

Oluşturduğunuz derslikı, koleksiyon oluştururken yahut önlaştırma gerektiren öteki senaryolarda kullanabilirsiniz.

Ryan LundyRyan Lundy 208k4141 gold badges183183 silver badges214214 bronze badges 3 4 Then why do we need this IEnumerable abstraction, if the only thing it does is just provide an access to Enumerator? Why don't just use Enumerator instead

the IEnumerable interface, so anything you birey do with a "plain" IEnumerable, you birey also do with an IQueryable. IEnumerable just başmaklık a GetEnumerator() method that returns an Enumerator for which you dirilik call its MoveNext() method to iterate through a sequence of T

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

There are many cases (such bey an infinite list or a C# IEnumerable Nasıl Kullanılır very large list) where IEnumerable cannot be transformed to a List. The most obvious examples are all the prime numbers, all the users of facebook with C# IEnumerable Nedir their details, or all the items on ebay. The difference is that "List" objects are stored "right here and right now", whereas "IEnumerable" objects work "just one at a time".

This takes an IEnumerator factory function, which usually birey be provided very easily C# IEnumerable Temel Özellikleri instead C# IEnumerable Temel Özellikleri 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.

IQueryable is faster than IEnumerable if we are dealing with huge amounts of veri from database because,IQueryable gets only required veri from database where birli IEnumerable gets all the data regardless of the necessity from the database

You should still avoid declaring the parameter type kakım List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
