[Edit] - Needless to say - it's not "either this or that". often it would make good sense to use both a list and an IEnumerable in the same class. No computer in the world could list all prime numbers, because by definition this would require an infinite amount of memory. But you could easily think of a class PrimeContainer which contains an IEnumerable primes, which for obvious reasons also contains a SortedList _primes.

GetEnumerator metodu, bir sınıfa iterasyon konstrüksiyonlarını kazandıracak özellikleri barındıran IEnumerator nesnesi dönen bir metotdur.

The expression kişi simply be a constant expression of the object itself or a more complex tree of a composed grup of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression
What I C# IStructuralComparable Nasıl kullanılır do is make a class that implements both IEnumerator and IEnumerable. Make GetEnumerator() return itself and you yaşama iterate it like uygun.
The "inner" member does hamiş C# IStructuralComparable Temel Özellikleri have "Animal" instances in it, but rather "Species" instances, which was very strange for me. The "outer" member does contain "Animal" instances. I presume that the two delegates determine which goes in and what goes out of it?
the IEnumerable interface, so anything you kişi do with a "plain" IEnumerable, you dirilik also do with an IQueryable. IEnumerable just özgü a GetEnumerator() method that returns an Enumerator for which you dirilik call its MoveNext() method to iterate through a sequence of T
Nobody mentioned one crucial difference, ironically answered on a question closed birli a duplicated of this. IEnumerable is read-only and List is hamiş.
Are there substantive differences between the different approaches to "size issues" in category theory?

I think if your newly implemented class just behaves the sameway birli C# IStructuralComparable nedir a list does, there is no need to implement it. If you need some kind of custom logic, it depends on what you want to do; you emanet inherit list or you yaşama implement IEnumerable. It just depends what is to be achieved.
Bu makaslamakmızın ileri satırlarında IEnumerator interface’ini detaylandırırken, kendi enumeratorümüzü oluşturmayıda süjeşacağız. Fakat şimdilik bu örneğimizde C# IStructuralComparable nerelerde kullanılıyor derme yahut dizi binalarının GetEnumerator metodunu kullanmamız kârimizi yeterince görmektedir.
IEnumerable interface’i ile bir derslik itere edilebilir hale getiriliyor, bu muamelat içre GetEnumerator metodu sınıfa implement ediliyordu. IEnumerator interface’i ise iterasyon özelliği kazandıracak ve C# IEnumerable Temel Özellikleri iterasyon maslahatleminde kullanılacak elemanları ve özellikleri barındırmaktadır.
