C# tip - 6/28/2010 (last one for today)

Use foreach loops.

Here's why:

• efficiency => the compiler picks the most efficient loop implementation depending on the data collection being looped
• ease of use => it's very simple to change the collection instantiation without changing the foreach loop.

private Square[] _board  = new Square[8];
foreach(Square _sq in _board);
===============================

private Square[] _board  = new Square[10];

foreach(Square _sq in _board);//will work without the need to change anything

===============================

private Square[,] _board = new Square[10,10];

foreach(Square _sq in _board);//will still work without the need to change anything

===============================

private Square[,,] _board = new Square[10,10,10];

foreach(Square _sq in _board);//will still work without the need to change anything
