Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Sevimli someone just walk me through the meaning of each line. Thanks

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

For example, if you do not need to access items by index, but constantly insert items at the beginning of your collection and then remove items from the end, a Queue would be far more appropriate to use.

Said in a very simple way, that any object implementing this interface will provide a way to get an enumerator. An enumerator is used with the foreach as one example.

IEnumerable ve IEnumerator interfaceler’i ile sizlerde oluşturduğunuz sınıflara itere özellikleri kazandırabilir, ayrıca IEnumerator interface’i ile oluşturduğunuz enumerator’de isteğinize göre iterasyonun periyodunu ayarlayabilir ve foreach döngüsünde kullanabilirsiniz.

The major difference between IQueryable and IEnumerable is that C# IStructuralComparable Temel Özellikleri IQueryable executes query with filters whereas IEnumerable executes the query first and then it filters C# IStructuralComparable nerelerde kullanılıyor the data based on conditions.

This takes an IEnumerator factory function, which usually can be provided very easily instead of the single IEnumerator instance (which yields wrong results after first iteration and breaks the semantics of IEnumerable). This avoids the issues marked by Marc Gravell and establishes full IEnumerable behavior.

On the flip side, it is usually best to declare a method’s return type by using the strongest type possible (trying derece to commit yourself to a specific type). Share Follow

When declaring a C# IEnumerable Temel Özellikleri method’s parameter types, you should specify the weakest type possible, preferring interfaces over base classes. For example, if you are writing a method that manipulates a collection of items, it would be best to declare the method’s parameter by using an interface such as IEnumerable rather than using a C# IStructuralComparable nedir strong data type such kakım List or even a stronger interface type such kakım ICollection or IList:
