Short story about a destan living on a fake tropical island / paradise planet, who was actually an adult CEO but didn't remember it
If you niyet to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.
Birli per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.
The following code example demonstrates the best practice for iterating a custom collection by implementing the IEnumerable and IEnumerator interfaces. In this example, members of these interfaces are not explicitly called, but they are implemented to support the use of foreach (For Each in Visual Basic) to iterate through the collection.
An Enumerable is a class that kişi give you Enumerators. It has 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 create the Enumerator used by the loop.
C# IEnumerable Extensions, C#’da bilincinde olarak ya da olmayarak sıkça IEnumerable’dan türemiş nesneleri kullanmaktayız. Peki nedir bu IEnumerable sorusuna yanıt verecek olursak, IEnumerable interface’i bizlere bir collection C# IEnumerable Nasıl Kullanılır üzerinde C# IEnumerable Temel Özellikleri iterasyon yapabilmemize olanak katkısızlamaktadır.

) without affecting original data." C# IEnumerable Temel Özellikleri is confusing. Do you mean that the new list returned kişi been added to, and elements güç be removed but no updates? I thought that because it returned ienumerable you can modify the elements in the list, i.e. change a property like you said but you güç't add and remove items in the list. Is that correct?
I do have one question though. In the first example you loop over the array using foreach but then you cannot do it in the second example. Is this because the array is in a class C# IEnumerable Temel Özellikleri or because it contains objects?
Then with a IQueryable the generated SQL will contains “where name = “a”, but with a IEnumerable many more roles will be pulled back from the database, then the x.name = “a” check will be done by .Kemiksiz.
diyerek sorarsak eğer üst satırlarda bahsettiğimiz gibi o dershaneın geriye IEnumerator nesnesi dönen GetEnumerator adlı metodu barındırıyor olması demekti. Ee haliyle IEnumerable interface’i ait sınıfa uygulanmış C# IEnumerable Nerelerde Kullanılıyor olduğunda GetEnumerator metodunu implement edecektir.
Bu interface, uygulandığı sınıfa GetEnumerator adlı bir metot kazandırır ve bu metot geriye IEnumerator interface’ini implement eden bir dershane döndürür.
By "functionally equivalent," I mean that's actually what the compiler turns the code into. You dirilik't use foreach on temel in this example unless
