This is to prevent old-calls from the previous level affecting the new loaded level.
it emanet be useful to use the iterators directly. A good example is when trying to "pair up" two different sequences. For example, suppose you receive two sequences - one of names, one of ages, and you want to print the two together. You might write:
Bear in mind that you don't have to implement IEnumerator and varients thereof to use foreach - IIRC, all it needs is a GetEnumerator() method that returns an object that başmaklık a MoveNext() method returning a bool, and a Current property returning an object.
Koleksiyonda öğe ekleme, değiştirme yahut silme üzere tadilat gestaltlırsa, numaralandırıcının davranışı tanımsızdır.
They güç be lazy. This is a subtle, useful (and sometimes dangerous) property. We don’t calculate any values until MoveNext is called, meaning we defer the work of generating the collection until we iterate the collection.
One thing that might stand out to you is the use of the switch statement in the MoveNext function. If that strongly resembles a finite state machine to you, that’s because it is one.
Most of the time, you'd just need foreach unless you're implementing your own type or custom iteration, in which case you'd need to get to know the first 2 interfaces.
IEnumerable ve IQueryable çoğu geliştirici C# IEnumerator nerelerde kullanılıyor aracılığıyla kullanmaı karıştırılmakta ve ne gün nerede kullanılacağı bilinmemektedir.
Some poor souls still insisted that C was still the better choice. I thought they were insane at the time; C wasn’t object-oriented! Everyone knew that object-oriented programming was objectively better that awful old imperative programming!
The basic reason you gönül't go that direction (IEnumerator to a IEnumerable) is that C# IEnumerator Temel Özellikleri IEnumerable represents a seki that gönül be enumerated, but IEnumerator is a specific enumeratation over a seki of items -- you kişi't turn the specific instance back into the thing that C# IEnumerator Önemi Nedir created it.
An IEnumerator is a thing that sevimli enumerate: it başmaklık the Current property and the C# IEnumerator Temel Özellikleri MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).
