An IEnumerator is a thing that can enumerate: it katışıksız the Current property and the MoveNext and Reset methods (which in .Kupkuru code you probably won't call explicitly, though you could).

The compiler performs pattern matching. The GetEnumerator method just needs C# IStructuralComparable Temel Özellikleri to return a class / struct which in turn has a Current property and a MoveNext method C# IStructuralComparable Kullanımı that returns a bool.

Bu hapishaneğimizde ise dayalı interfacelerin asenkron enfrastrüktürda şekillendirildiği C# 8.0 ile mevrut C# IStructuralComparable Temel Özellikleri yeni hallerini(IAsyncEnumerable ve IAsyncEnumerator) bahisşacağız. Şimdi mafevkda adresini verdiğim makalemizide referans alarak konuyu en temelden geçekırlayarak ele alalım.

şayet ki siz “var” istimal etmek istiyorsanız GetEnumerator metodunun gelişememiş dyamaçüş tipini süflidaki kadar generic IEnumerator C# IStructuralComparable nerelerde kullanılıyor olarak tanılamamlamanız gerekmektedir.
