@OlivierJacot-Descombes: Short of using Reflection, there's no way of knowing whether an IList which allows anything of a given type to be stored by index will allow everything of that type to be stored by index.

Yaşama a unique position be deduced if pieces are replaced by checkers (can see piece color but hamiş type)

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

e., using IEnumerable instead of List where possible) provides exactly that decoupling while also requiring proper design philosophy. That is to say, you sevimli achieve decoupling but hamiş achieve minimal dependency, but you cannot achieve minimal dependency without achieving maximal decoupling.

This will create a new list element for each element in memory, enumerating the IEnumerable and is thus less performant if you only enumerate once - but safer and sometimes the List methods are handy (for instance in random access).

B. IEnumerator kişi remember the current index when we pass from one method to another (it start working with current index) but IEnumerable yaşama't remember the index and it reset the index to beginning. More in this video

List: List sınıfı, hareketli boyutlarda sıralı koleksiyonlar bâtınin kullanılır ve bu tür koleksiyonlarda elemanları gezinmek için IEnumerator yararlanmaı yaygındır.

This way you have possibility to do C# IEnumerable Kullanımı many things with that query without touching the C# IEnumerable Kullanımı data (in this case data in the list). List method takes the prepared query and executes it against the source of data.

Yield ile kendimiz named iteretor'ler oluşturabiliriz. Örneğin programımızın C# IEnumerable Temel Özellikleri 750TL den elan pahalı ürünleri getirmesini istiyoruz:

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical data or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' veri if it's able to do so or throw an exception if it hayat't, and an ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit late now to change C# IEnumerable Temel Özellikleri things, though.

This yaşama be very useful in certain circumstances, for instance in a massive database table you don't want to copy the entire thing into memory before you start processing the rows.

diyerek sorarsak şayet üst satırlarda bahsettiğimiz gibi o sınıfın geriye IEnumerator nesnesi dönen GetEnumerator isminde metodu barındırıyor olması demekti. Ee haliyle IEnumerable interface’i alakalı sınıfa uygulandığında GetEnumerator metodunu implement edecektir.

Why does the Clausius inequality involve a single term/integral if we consider a body interacting C# IEnumerable Nasıl Kullanılır with multiple heat sources/sinks?

If you are writing a class, and your class implements the IEnumerable interface (generic (T) or hamiş) you're allowing any consumer of your class to iterate over its collection without knowing how it's structured.
