IEnumerators can be iterated with a while loop:

// Call a custom method that takes a count, and returns an IEnumerator for a list
// of strings with the names of theh largest city metro areas.
IEnumerator<string> largestMetroAreas = GetLargestMetroAreas(4);

while (largestMetroAreas.MoveNext())
{
    Console.WriteLine(largestMetroAreas.Current);
}

Sample output:

Tokyo/Yokohama
New York Metro
Sao Paulo
Seoul/Incheon
