  4. 0348 Array Enumeration
You can enumerate using the static Array.ForEach method:

public static void ForEach (T[] array, Action action);

This uses an Action delegate, with this signature:

public delegate void Action (T obj);

using System;
using System.Collections;
class Sample
{
public static void Main()
{
Array.ForEach(new[] { 1, 2, 3 }, Console.WriteLine);
}
}
The output:
1
2
3
