If your class is a custom collection class then yes, it should implement IEnumerable. In this case a public property for the inner list would be redundant. Imagine a simple class:

, so if you're doing complicated work to evaluate the enumerable as 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 hamiş need to do the work at all.

The second method allows only List objects to be passed in; it will hamiş accept an array or a String object. Obviously, the first method is better because it is much more flexible and hayat be used in a much wider range of scenarios.

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.

What about IEnumerable, its just a way to make a returning type generic, and not make strong coupling to List type.

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

IEnumerable is a generic interface describing something that can be enumerated (you sevimli iterate through it and see/retrieve all of its elements). The content C# IStructuralComparable Kullanımı of this IEnumerable emanet have been pre-generated, or is live/lazily generated when you try to iterate through 'result' (IEnumerable).

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

Your linq expression returns an enumeration, and by default the expression executes when you iterate through using the foreach. An IEnumerable linq statement executes when you iterate the foreach, but you emanet force it to iterate sooner using .ToList().

Using the concept of iterators you emanet achieve major improvement in algorithm quality, both in terms of speed and memory usage.

Bu alanda veya gayrı bir alanda, benim ve sair yardımcı insanoğluın paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm şeşna girmeniz anlamına gelmemektedir.

There's also the C# IStructuralComparable nedir issues of deferred execution and unmanaged resources. IEnumerable takes use of the yield syntax, which mean you go over each item by-itself and emanet perform all kinds of computations before and after. And again, this happens one-by-one, so you don't have to hold all C# IEnumerable Nerelerde Kullanılıyor the collection when you start. The computations won't actually be performed until the enumeration begins (i.e. until you run the foreach loop).
