10. Part 1 Strong Type

11. IEnumerable

12. foreach

13. for (int i = 0; i < foos.Count(); i++) { Foo f = foos.ElementAt(i); // Do something } foreach (Foo f in foos) { // Do something }

14. for (int i = 0; i < foos.Count(); i++) { Foo f = foos.ElementAt(i); // Do something } foreach (Foo f in foos) { // Do something }

15. DON’T DO THIS FOR i := 0 TO Foos.Count - 1 DO BEGIN Foo := Foos.Item(i); END;

16. DO THIS INSTEAD Enumerator := Foos.GetEnumerator; WHILE Enumerator.MoveNext DO BEGIN Foo := Enumerator.Current; END;
