The low level iterator manipulate code:
List<Money> myMoney = new List<Money>
{
new Money{amount = 10, type = "US"},
new Money{amount = 20, type = "US"}
};
using (var enumerator = myMoney.GetEnumerator())
{
while (enumerator.MoveNext())
{
var element = enumerator.Current;
Console.WriteLine(element.amount);
}
}
