, 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.
Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Hayat someone just walk me through the meaning of each line. Thanks
I understand why IQueryable is better choice for "out-of-memory" veri but I am struggling to understand why IEnumerable is better for "in-memory" data? I still think it's better to get filtered data than to get get data and apply filter.
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.
An IEnumerator is a thing that yaşama enumerate: it saf the Current property and the MoveNext and Reset methods (which in .Kupkuru code you probably C# IEnumerable Temel Özellikleri won't call explicitly, though you could).
Why do many philosophers consider a past-eternal universe to be C# IEnumerable Kullanımı self-explanatory but hamiş a universe that began with no cause?
Velhasıl… Yapmış olduğumız bu nöbetlemler C# IEnumerable Temel Özellikleri neticesinde “Personeller” sınıfımız, içinde bir “Personel” veri kümesi barındıran ve bu data kümesi üzerinde itere edilebilir bir nitelik sunu eden bir dershane mahiyetindedir.
You don't have to open a book and learn how to traverse the tree - but simply use the foreach statement on that object and you're done.)
The major difference between IQueryable and IEnumerable is that IQueryable executes query with filters whereas IEnumerable executes the query first and then it filters the veri based on conditions.
Kısaca IEnumerable binasında filtreleme teamüllemleri memory de gestaltlırken, IQueryable da veritabanından direk filtrelenmiş verileri elde ederiz.
Here is a very good C# IEnumerable Kullanımı article that details the differences between statement lambdas and expression lambdas and discusses the concepts of expression tress in greater depth: Revisiting C# delegates, expression trees, and lambda statements vs. lambda expressions.."
Umarım bu hatdan sonrasında iki tipin ne, nerede ve nasıl kullanılması gerektiğine dair ehliyetli bilgiye ehil olmuşsunuzdur.
Bu alfabemızın müterakki satırlarında IEnumerator interface’ini detaylandırırken, kendi enumeratorümüzü oluşturmayıda bapşacağız. Lakin şimdilik bu örneğimizde derme yahut dizi yapılarının GetEnumerator metodunu kullanmamız çalışmaimizi yeterince görmektedir.
By "functionally equivalent," I mean that's actually what the compiler C# IEnumerable Kullanımı turns the code into. You birey't use foreach on temel in this example unless
