IEnumerator arayüzü, data dokumalarına umumi bir erişim yöntemi katkısızlayarak kodun daha modüler olmasını ve bakımının kolaylaşmasını sağlar. Hassaten, C# programlamada münteşir olarak kullanılan bu reçete, kodun okunabilirliğini pozitifrır ve gene kullanılabilirliği özendirme fiyat.

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

I have writen about custom IEnumerator. Whats the simplest way to make IEnumerable from it ? ülkü solution (one line of code) would be if there was some class for that purpose. Or do I have to create my own ?

The syntax (which you rarely see because there are prettier ways to do it) for moving through a collection that implements IEnumerable is:

Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the yetişek. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:

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 iterate over it :)

My question is that should these classes instead implement the IEnumerable interface, and call GetEnumerator on the List itself.
