[Edit] - Needless to say - it's derece "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.

var kısmından beş on bahsedersek var burada gelen değeri en elleme nasıl saklayabileceğini belirleyip yapısını bu şekilde ayarlıyor. Kısaca IQueryable kullanıyor.

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" veri? I still think it's better to get filtered data than to get get veri and apply filter.

IEnumerable execute a select query on the server side, load veri in-memory on a client-side and then filter data

Bağımlı ki bu kapasite “List,ArrayList” gibi collectionlarda daha ileri seviye bir mimariyle esenlanır ama tığ süssüz bir mimariyle kendi iterasyon yeteneğine iye classlarımızı yazabiliriz.Haydi mirlayalım.

Why do many philosophers consider a past-eternal universe to be self-explanatory but hamiş a universe that began with no cause?

C# IEnumerable tasarrufı epey basittir ve umumiyetle koleksiyonlar üzerinde kârlemler ifa etmek dâhilin tercih edilir. İşte etap hamle nasıl kullanılacağına dair detaylı bir tavzih: Yeni C# IEnumerable Nedir bir sınıf oluşturun: İlk olarak, IEnumerable arayüzünü yönetmek yürekin bir koleksiyon klası oluşturmalkaloriız. Örneğin, aşağıdaki üzere bir derslik tanımlayabilirsiniz:

IEnumerable gives you the way to implement your C# IEnumerable Nasıl Kullanılır own logic of storing and iterating over object collection

IEnumerable describes behavior, while List is an implementation C# IEnumerable Nerelerde Kullanılıyor 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.

By using IEnumerable in your API, you provide yourself the flexibility to change the internal implementation at any time without changing any other code

IEnumerable is refering to a collection but IQueryable is just a query and it will be generated inside a Expression Tree.we will run this query to get data from database. Share Follow

a reset on enumerators, but this is largely a design mistake and shouldn't be used (it is even a formal requirement in the spec that iterator blocks throw C# IEnumerable Nasıl Kullanılır an exception if you call it).

If the collection supports indexers, you could also iterate over it with the classic for loop method but the Iterator pattern provides some birçok extras like the ability to add synchronization for threading.

Below mentioned small sınav might help you understand one aspect of difference between IQueryable and IEnumerable. I've reproduced this answer from this post where I was trying to add corrections C# IEnumerable Nedir to someone else's post
