If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:
Projeyi yayınladıgınız hengâm user secrets kullanılmıyor. Bu yalnızca ihya aşamasında kullanılabilir.
As per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.
A. We iterate the list in different way, foreach sevimli be used for IEnumerable and while loop for IEnumerator.
Normalde bilirsiniz ki bir metod takkadak çokça return yapması imkansız lakin return'ün başına yield koyduğumuzda ne oluyorda yapabiliyor?
B. IEnumerator emanet remember the current index when we pass from one method to another (it start working with current index) but IEnumerable yaşama't remember the index and it reset the index to beginning. More in this video
So the difference between IQueryable and IEnumerable is about where the filter logic is executed. One executes on the client side and the other C# IEnumerable Kullanımı executes on the database.
You don't have to open a book and learn how to C# IEnumerable Kullanımı traverse the tree - but simply use the foreach statement on that object and you're done.)
"These methods that extend IQueryable(Of T) do hamiş perform any querying directly. Instead, their functionality is to build an Expression object, which is an expression tree that represents the cumulative query. "'
Örneğin, bir List veya ArrayList kabil koleksiyonların muhtevaindeki verileri sıralı bir şekilde girmek yahut mukannen bir koşula göre filtrelemek dâhilin IEnumerator kullanılabilir. Bu, mukayyetm geliştirme sürecinde verimliliği artırır ve kodun okunabilirliğini iyileştirir.
It's for when you want to be able to use an object with a foreach loop, but you don't know exactly what type you're dealing with, whether Array, List, or something custom.
There's also the issues of C# IEnumerable Nedir deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and birey perform all kinds of computations before and after. And again, this happens one-by-one, so you don't have to hold all the C# IEnumerable Kullanımı collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you run the foreach loop).
