[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.

I noticed that if I use IEnumerable, when I debug and inspect "baskın", which in that case is the IEnumerable, it özgü some interesting members: "inner", "outer", "innerKeySelector" and "outerKeySelector", these last 2 appear to be delegates.

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

The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are hamiş explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to C# IEnumerable Temel Özellikleri iterate through the collection.

System.Collections.IEnumerator. This interface provides the infrastructure to allow the caller to traverse the internal objects contained by the IEnumerable-compatible container:

Basically it saf a method to get the next item in the collection. It doesn't need the whole collection to be in memory and doesn't know how many items are in it, foreach just keeps getting the next item until it runs out.

IEnumerator interface inden gelen “Current” propertysinin get metodunda kendi tanımladığımız “Current” property’sini return ettik.

For small C# IEnumerable Nerelerde Kullanılıyor result sets this is likely to be a single trip, for large ones you're sending a request for more rows from the results, but it doesn't re-run the entire query.

Bu alanda yahut farklı bir alanda, benim ve başka yardımcı insanoğluın paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm şeşna girmeniz manaına gelmemektedir.

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.

Consider the below simple code which uses IEnumerable with entity framework. It’s using a Where filter C# IEnumerable Nedir to get records whose EmpId is 2.

IEnumerator kullanarak, koleksiyonun topu topunı belleğe yüklemeden, sadece mukteza elemanları maslahatler ve bu sayede belleğin etkin kullanılmasını katkısızlar.

You should C# IEnumerable Nedir still avoid declaring the parameter type birli List. Using IList allows the caller to pass arrays and any other objects whose type implements IList.
