The only situation in which you cannot avoid using the iterator is when you must remove elements from a List collection. The following code shows how this is accomplished.
X++:
List list = new List(Types::Integer);
ListIterator iterator;
;
list.addEnd(100);
list.addEnd(200);
list.addEnd(300);
iterator = new ListIterator(list);
while (iterator.more())
{
if (iterator.value() == 200)
iterator.delete();
iterator.next();
}
print list.toString(); //{100, 300}
pause;
В коде логическая ошибка. Перед iterator.next() необходим else.
