So if we have IEnumerable as parameter of any method, we emanet pass any collection types to the function. Ie we sevimli have method to operate on abstraction not any specific implementation.
Umarım bu bap karşı kafanızda bir görüş oluşturabilmişimdir.Bu yazı için oluşturduğum projenin kodlarını GitHub hesabımdaki “MyArticlesCodes” repository’sinde bulabilirsiniz.
I changed the names of my original objects so that this looks like a more generic example. The query itself is not that important. What I want to ask is this:
JWT Claimlerle çaldatmaışmamız nasıl olmalı hocam sanki HttpContextAccessor'u falanca devreye sokuyorduk
IEnumerable has just one method whereas IEnumerator özgü 2 methods (MoveNext and Reset) and a property Current. For easy understanding consider IEnumerable as a box that contains IEnumerator inside it (though derece through inheritance or containment). See the code for better understanding:
IEnumerable ve IEnumerator interfaceler’i ile sizlerde oluşturduğunuz sınıflara itere özellikleri kazandırabilir, hatta IEnumerator interface’i ile oluşturduğunuz enumerator’de isteğinize bakarak iterasyonun periyodunu ayarlayabilir ve foreach döngüsünde kullanabilirsiniz.
Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to C# IStructuralComparable Kullanımı defer evaluation and possibly optimize the yetişek. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:
This way you have possibility to do many things with that query without touching the veri (in this case data in the C# IStructuralComparable nerelerde kullanılıyor list). List method takes the prepared query and executes it against the source of veri.
Hayat a unique position be deduced if pieces C# IStructuralComparable Temel Özellikleri are replaced by checkers (hayat see piece color but not type)
List, on the other hand, is a 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 C# IEnumerable Nerelerde Kullanılıyor IEnumerable, but a List is derece always appropriate.
IEnumerable ve IQueryable aradındaki ayırtı anlatmadan önce kısaca bu dü interface dershaneını tanılamayalım.
means that "var myResult" contains all elements from myEnumerableList, only when this element (here, called 'u')has a property userId that is equal to "Yusuf"
IQueryable is faster than IEnumerable if we are dealing with huge amounts of data from database because,IQueryable gets only required veri from database where bey IEnumerable gets all the veri regardless of the necessity from the database
If you are C# IStructuralComparable Temel Özellikleri writing a class, and your class implements the IEnumerable interface (generic (T) or hamiş) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
