However, if you would prefer to hide the functionality of IEnumerable from the object level,

simply make use of explicit interface implementation:

IEnumerator IEnumerable.GetEnumerator()

{

// Return the array object's IEnumerator.

return carArray.GetEnumerator();

}

By doing so, the causal object user will not find the Garage’s GetEnumerator() method, while the

foreach construct will obtain the interface in the background when necessary.
