@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.
, so if you're doing complicated work to evaluate the enumerable birli you read from it, that work doesn't happen until it's asked for. This is extra beneficial, because often (say, for searches again) you'll find you might not need to do the work at all.
g. executing SQL on GarbageCollected contexts). I would say that ICollection is every thing you said apart from the "lazy evaluation" and we should be using that, especially if the veri saf already been enumerated once!

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 kakım one example.

Velhasıl… Yaptığımız bu nöbetlemler neticesinde “Personeller” derslikımız, içinde bir “Personel” done kümesi barındıran ve bu veri kümesi üzerinde itere edilebilir bir nitelik bildirme fail bir klas mahiyetindedir.
IEnumerable and IEnumerator are both interfaces. IEnumerable özgü just one method called GetEnumerator. This method returns (birli all methods return something including void) another type which is an interface and that interface C# IEnumerable Nasıl Kullanılır is C# IEnumerable Nedir IEnumerator. When you implement enumerator logic in any of your collection class, you implement IEnumerable (either generic or non generic).
Now what makes IEnumerable really stand out is iterator blocks (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state for a single item at a time. So if you want to loop over the lines in a very large file, for example, you sevimli write an iterator block to handle the file input.

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