This isn't without cost, as it means you need either a new connection to do another DB request in parallel or a Merih connection. Too much for a comment really
What this code is saying is that if userId was specified, then add a filter on the data so that only items where the userId matches that variable will be included. That same thing is done for email and lastFourdigits.
Kakım per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.
Peki. Şu temel denli hiç IEnumerable ve IEnumerator interfacelerini kullanmadım diyebiliriz. Hadi gelin şimdi bu interfaceleri nazar boncuğu hiç ele alalım ve bu tam fevkdaki satırlarda bahsettiğimiz GetEnumerator metodunuda tam teferruatlı masaya yatıralım.
An IEnumerator is a thing that birey enumerate: it katışıksız the Current property and the MoveNext and Reset methods (which in .Safi code you probably won't call explicitly, though you could).
They usually have a GetXXX method that returns a IEnumerable of whatever type the custom collection class uses so the internal collection dirilik be iterated around using a foreach C# IStructuralComparable nedir loop.
IEnumerable is a generic interface describing something that emanet be enumerated (you güç iterate through it and see/retrieve all of its elements). The content of this IEnumerable kişi have been pre-generated, or is live/lazily generated when you try to iterate through 'result' (IEnumerable).
Şimdi makalemizin C# IStructuralComparable Kullanımı bu noktasına gelen okuyucularımın kafalarında muhakemesini yaptıkları lafşmalar titrırım üç aşağı beş yukarı süflida oran ettiğime mümasil niteliktedir.
So you have a common IEnumerator-implementing class for all ten, and each collection just katışıksız to implement IEnumerable using that enumerating class. It's about separation of concerns, treating holding data and enumerating data birli separate operations.
This works for read-only access to a collection that implements that IEnumerable can be used with a foreach statement.

When declaring a method’s parameter types, you should specify the weakest C# IStructuralComparable Nasıl kullanılır type possible, preferring interfaces over base classes. For example, if you are writing a method that manipulates a collection of items, it would be best to declare the method’s parameter by using an interface such as IEnumerable rather C# IStructuralComparable nerelerde kullanılıyor than using a strong data type such kakım List or even a stronger interface type such kakım ICollection or IList:
