This isn't without cost, kakım it means you need either a new connection to do another DB request in parallel or a MARS connection. Too much for a comment really
So when you have to simply iterate through the in-memory collection, use IEnumerable, if you need to do any manipulation with the collection like Dataset and other veri sources, use IQueryable

It's effectively usage bey documentation of intent; I find that those explicit documentations of intent tend to provide exactly that decoupling you point out.
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 as one example.
Eğer şimdiye denli forearch yapısını kullandıysanız esasen foreach kuruluşsında döngüyü sağlayan hadise alttaki listedede görebileceğiniz gibi IEnumarable sınıfından türetilen nesneleri kullanıyor olmamızdır.
This is a birçok video on youtube which demonstrates how these interfaces C# IEnumerable Nerelerde Kullanılıyor differ , worth a watch. Below goes a long descriptive answer for it.
IEnumerable gives C# IEnumerable Nasıl Kullanılır you the way to implement your own logic of storing and iterating over object collection
IEnumerable describes behavior, while List is an C# IEnumerable Temel Özellikleri implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.
List, on the other hand, is a specific implementation of IEnumerable that stores the objects in a specific, known manner. Internally, this may be a very good way to store your values that you expose via IEnumerable, but a C# IEnumerable Nerelerde Kullanılıyor List is hamiş always appropriate.
Does it bring the whole collection in memory? Or, does it instantiate the element one by one, birli it iterates over the foreach loop? thanks
Umarım bu alfabedan sonra dü tipin münasebet, nerede ve nasıl kullanılması gerektiğine değgin yeterli bilgiye ehil olmuşsunuzdur.
Bu interface, uygulandığı sınıfa GetEnumerator adlı bir metot kazandırır ve bu metot geriye IEnumerator interface’ini implement eden bir dershane döndürür.
Why does the Clausius inequality involve a single term/integral if we consider a body C# IEnumerable Kullanımı interacting with multiple heat sources/sinks?
