Implementation of IEnumerable is generally the preferred way for a class to indicate that it should be usable with a "foreach" loop, and that multiple "foreach" loops on the same object should operate independently.
Bu iki arayüzün yararlanma senaryoları farklıdır ve birbirlerinin adına kullanılmamalıdır. Bu makalede, IEnumerable ve IQueryable arasındaki farkları inceleyeceğiz.
The second method allows only List objects to be passed in; it will not accept an array or a String object. Obviously, the first method is better because it is much more flexible and can be used in a much wider range of scenarios.

IEnumerable and IEnumerator are both interfaces. IEnumerable C# IStructuralComparable Temel Özellikleri has just one method called GetEnumerator. This method returns (birli all methods return something including void) another type which is an interface and that interface is IEnumerator. When you implement enumerator logic in any of your collection class, you implement IEnumerable (either generic or non generic).
The major difference between IQueryable and IEnumerable is that IQueryable executes query with filters whereas IEnumerable executes the query first and then it C# IStructuralComparable nedir filters the data based on conditions.
Kısaca IEnumerable kuruluşsında filtreleme işlemlemleri memory bile mimarilırken, IQueryable da veritabanından direk filtrelenmiş verileri elde ederiz.

The most conservative approach would be for you to cache all the items inside your new enumerable, to handle enumerators that birey only be enumerated once, so there is no general class for this in the runtime.
