Fevkdaki hatada Calisan klasının bir GetEnumerator içermediğini C# IStructuralComparable nedir belirtiyor. Doğrusu buradan da şu çıihtiyarmı yapabiliriz;

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable gönül be used with a foreach statement.

Why does C# IStructuralComparable Temel Özellikleri the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?
