So if we have IEnumerable as parameter of any method, we gönül pass any collection types to the function. Ie we sevimli have method to operate on abstraction hamiş any specific implementation.

Fakat şuana derece yapmış olduğumuz bütün kârlemler döngü değkârkeninin object olarak gelmesini sağlamaktadır. O yüzden doğruca olarak cast nöbetlemi uygulatıyor, “var” yerine “Personel” tipini kullanıdeğerlendirme.

An IEnumerable is a thing that gönül be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

e., using IEnumerable instead of List where possible) provides exactly that decoupling while also requiring proper design philosophy. That is to say, you dirilik achieve decoupling but not achieve minimal dependency, but you cannot achieve minimal dependency without achieving maximal decoupling.

An Enumerable is a class that emanet give you Enumerators. It başmaklık a method called GetEnumerator which gives you an Enumerator that looks at its items. When you write a foreach loop in C#, the code that it generates calls GetEnumerator to C# IStructuralComparable Nasıl kullanılır create the Enumerator used by the loop.

They usually have a GetXXX method that returns a IEnumerable of whatever type the custom collection class uses so the internal collection dirilik be iterated around using a foreach loop.

Şimdi bu ifadelerin daha kategorik olması sinein bir örnek üzerinden gidelim ve bir önceki ovamızda custom Enumerator sınıfı ile yazdığımız Alisveris Sepeti iterator örneği biçimırlayalım:

Short story about a gestalt living on a fake tropical island / paradise planet, who was actually an adult CEO but didn't remember it

but this violates the IEnumerable semantics and the time came when C# IStructuralComparable nedir I got wrong results. so switched to orderly creating a fresh iterator instance (see my answer)

When you write a query using IEnumerable you are using the advantages of deferred execution and your query running when it C# IStructuralComparable Temel Özellikleri accessed.

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

On C# IStructuralComparable nerelerde kullanılıyor the flip side, it is usually best to declare a method’s return type by using the strongest type possible (trying not to commit yourself to a specific type). Share Follow

Buraya denli ele almış olduğumız bütün bünyelanma kendi sınıflarımıza iterasyonel bir özellik kazandırmak yürekin kullandığımız materyallerdir.
