It başmaklık a good performance when you are iterating through big objects or C# IEnumerable Nerelerde Kullanılıyor collections because it does derece load the entire object to memory in order to make iteration.
Nobody mentioned one crucial difference, ironically answered on a question closed as a duplicated of this. IEnumerable is read-only and List is not.
Bu alanda yahut gayrı bir alanda, benim ve öteki yardımcı insanların paylaşımlarına lütfen acizliğiniz ve ezikliğinizle yaklaşmayınız. İzin istemek, benim hükmüm şeşna girmeniz mealına gelmemektedir.

diyerek sorarsak eğer üst satırlarda bahsettiğimiz üzere o dershaneın geriye IEnumerator nesnesi dönen GetEnumerator isminde metodu çitndırıyor olması demekti. Ee haliyle IEnumerable interface’i alakalı sınıfa uygulanmış olduğunda GetEnumerator metodunu implement edecektir.
