IEnumerator arayüzü, muta kuruluşlarına umumi bir ulaşım yöntemi esenlayarak kodun henüz modüler olmasını ve hizmetının kolaylaşmasını sağlar. Başkaca, C# programlamada yaygın olarak kullanılan bu teknik, kodun okunabilirliğini zaitrır ve gene kullanılabilirliği isteklendirme değer.

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

Nihayetinde burada ortaya çıdem sonuç; IEnumerable interfaceinin uygulandığı sınıfa zorla GetEnumerator isimli metot implement ettirilmektedir. IEnumerator ise ilişkin sınıfa iterasyon ustalıkleminde kullanılacak elemanları ve özellikleri kazandırmaktan mesul olacaktır.

So if you working with only in-memory veri collection IEnumerable is a good choice but if you want to query veri collection which is connected with database `IQueryable is a better choice as it reduces network traffic and uses the power of SQL language.

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support C# IEnumerable Temel Özellikleri 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 dirilik'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 things, though.

This takes C# IEnumerable Nedir an IEnumerator factory function, which usually gönül be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). C# IEnumerable Kullanımı This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.

Generally, don't worry about what's actually in the IEnumerables, kakım it will be completely different from your actual code. Only worry about the actual output when you C# IEnumerable Nedir iterate over it :)
