Data rahatışı ve LINQ sorguları: IEnumerable, Language Integrated Query (LINQ) sorgularında münteşir olarak kullanılır. LINQ, done koleksiyonları üzerinde sorgulama ve filtreleme gibi işlemlemleri kolaylaştırır ve performansı zaitrır.
Anything in .Kemiksiz that you hayat iterate over implements IEnumerable. If you're building your own class, and it doesn't already inherit from a class that implements IEnumerable, you sevimli make your class usable in foreach statements by implementing IEnumerable (and by creating an enumerator class that its new GetEnumerator method will return).
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.
Now List implements IEnumerable, but represents the entire collection in memory. If you have an IEnumerable and you call .ToList() you create a new list with the contents of the enumeration in memory.
Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach bey one example.
static public IEnumerable VerileriGetir() yield return "Pazartesi"; yield return "Salı"; yield return "Çarşamba"; yield return "Perşembe"; yield return "Cuma"; yield return "Cumartesi"; yield return "Pazar"; Şimdi kötüdaki şifre bloğunu detaylıca inceleyelim.

The constructor is derece responsible for returning data to the caller. 2-We need to call a method that returns the cars array. That is in a real-world case, a method that returns an array should be coded in Garage and it should return an array, in which case, there would be no need to use IEnumerable.

Any idea why the Enumerable is "split" into "inner" and "outer"? This happens when I inspect the element in C# IStructuralComparable Temel Özellikleri debug/break mode via mouse. Is this perhaps Visual Studio's contribution? Enumerating on the tanıtımcık and indicating input and output of the Enum?
