using System; public class SamplesArray { public static void Main() { // create a three element array of integers int[] intArray = new int[] {2, 3, 4}; // set a delegate for the ShowSquares method Action<int> action = new Action<int>(ShowSquares); Array.ForEach(intArray, action); } private static void ShowSquares(int val) { Console.WriteLine("{0:d} squared = {1:d}", val, val*val); } } /* This code produces the following output: 2 squared = 4 3 squared = 9 4 squared = 16 */
