Kakım per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.
A. We iterate the list in different way, foreach can be used for IEnumerable and while loop for IEnumerator.
Although there are uses of IEnumerable other than "foreach", the normal indication that one should implement IEnumerable is that the class is one where it would make sense to say "foreach foo in classItem foo.do_something(); .
Quoting that article, 'Bey per the MSDN documentation, calls made on IQueryable operate by building up the internal expression tree instead.

Now what makes IEnumerable really stand out is iterator blocks (the yield C# IEnumerable Kullanımı keyword C# IEnumerable Nedir in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state for a single item at a time. So if you want to loop over the lines in a very large file, for example, you kişi write an iterator block to handle the file input.

Generally, don't worry about what's C# IEnumerable Temel Özellikleri actually in the IEnumerables, bey it will be completely different from your actual code. Only worry about the actual output when you iterate over it :)
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 sevimli be used with a foreach statement.
When declaring a method’s parameter types, you should C# IEnumerable Temel Özellikleri 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 C# IEnumerable Nasıl Kullanılır would be best to declare the method’s parameter by using an interface such as IEnumerable rather than using a strong data type such as List or even a stronger interface type such as ICollection or IList:
