Different implementations of collections can be enumerable; using IEnumerable makes it clear that what you're interested in is the enumerability, and not the structure of the underlying implementation of the collection.
A. We iterate the list in different way, foreach hayat be used for IEnumerable and while loop for IEnumerator.
C# IEnumerable, IEnumerator Aralık yüzleri ve Yararlanmaı makaslamaksında bahsettiğimiz gibi bir dershaneımızın iterator özelliği kazanabilmesi bâtınin IEnumerable veya IEnumerable interfacelerini implemente etmesi gerekmektedir.
The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:
Velhasıl… Yaptığımız bu çalışmalemler neticesinde “Personeller” sınıfımız, içinde bir “Personel” bilgi kümesi çitndıran ve bu data kümesi üzerinde itere edilebilir bir nitelik en eden bir sınıf mahiyetindedir.
You don't have to open a book C# IStructuralComparable nedir and learn how to traverse the tree - but simply use the foreach statement on that object and you're done.)
) without affecting original data." is confusing. Do you mean that the new list returned birey been added to, and elements birey be removed but no updates? I thought that because it returned ienumerable you birey modify the elements in the list, i.e. change a property like you C# IStructuralComparable nedir said but you yaşama't add and remove items in the list. Is that correct?
When you write a query using IEnumerable you are C# IStructuralComparable Kullanımı using the advantages of deferred execution and your query running when it accessed.
Does it bring C# IStructuralComparable Nasıl kullanılır the whole collection in memory? Or, does it instantiate the element one by one, as it iterates over the foreach loop? thanks
But C# IStructuralComparable nedir if your class cannot act like a collection then provide a public IEnumerable property for its elements:

The most conservative approach would be for you to cache all the items inside your new enumerable, to handle enumerators that birey only be enumerated once, so there is no general class for this in the runtime.
In addition to all the answers posted above, here is my two cents. There are many other types other than List that implements IEnumerable such ICollection, ArrayList etc.
