using System;
using System.Collections; // for non generic collections like ArrayList

namespace Console_ArrayList
{
    class Program
    {
        static void Main(string[] args)
        {
            ArrayList arrList = new ArrayList();
            arrList.Add(2);
            arrList.Add(4);
            arrList.Add(7);
            arrList.Add("Ajeet");
            arrList.Add("Rajeev");

            int[] array1 = { 1, 3, 5, 8, 6, 9 };
            arrList.AddRange(array1); //AddRange adds an array

            Console.WriteLine("List of all added heterogeneous items to ArrayList");

            foreach (var item in arrList)
            {
                Console.WriteLine(item);
            }
