Foreach Loops

A foreach loop can be used to iterate over each of the elements in a collection. The collection can be held in an array or in a parameterized container, like a List, as shown in the program. Due to the nature of foreach loops, elements may not be added or removed during its execution in order to prevent the erractic behavior that would result.

Program.cs

using System;
using System.Collections.Generic;

namespace XoaX {
    class Program {
        static void Main(string[] args) {
            // Array
            int[] iaSacredNumbers = { 40, 7, 12, 3 };
            foreach (int i in iaSacredNumbers) {
                Console.Write(i + "  ");
            }
            Console.WriteLine();

            // List
            List<string> qProphets = new List<string>();
            qProphets.Add("Isaiah");
            qProphets.Add("Jeremiah");
            qProphets.Add("Daniel");
            qProphets.Add("Ezekiel");
            qProphets.Add("Jonah");
            qProphets.Add("Elijah");
            foreach (string sProphet in qProphets) {
                Console.Write(sProphet + "  ");
            }
            Console.WriteLine();
        }
    }
}

Output

40  7  12  3
Isaiah  Jeremiah  Daniel  Ezekiel  Jonah  Elijah
