, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more data than is actually needed, and we waste cycles doing the filtering in the client.

Ama şuana denli yapmış başüstüneğumuz bütün kârlemler döngü değçalışmakeninin object olarak gelmesini sağlamaktadır. O yüzden aracısız olarak cast alışverişlemi uygulatıyor, “var” yerine “Personel” tipini kullanıversiyon.

I understand why IQueryable is better choice for "out-of-memory" data but I am struggling to understand why IEnumerable is better for "in-memory" veri? I still think it's better to get filtered data than to get get data and apply filter.

For example, if you do not need to access items by index, but constantly insert items at the beginning of your collection and then remove items from the end, a Queue would be far more appropriate to use.

To get them I use VisualTreeHelper class. But I have to consider that there might be A LOT OF children so copying to some array or Collection will by expensive. – drasto 5 mins ago

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

IEnumerable and IEnumerator are both interfaces. IEnumerable has just one method called GetEnumerator. This method returns (as all methods return something including void) another type which is an interface and C# IEnumerable Temel Özellikleri that interface is IEnumerator. When you implement enumerator logic in any of your collection class, you implement IEnumerable (either generic or non generic).

If you made the return of AllSpotted() and the parameters of Feline() and Canine() into IQueryable, then the filter would happen in SQL and this answer would make sense.

I think if your newly implemented class just behaves the sameway kakım a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you want to do; you hayat inherit list or you dirilik implement IEnumerable. It just depends what is to be achieved.

My question is that should these classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.
