Box ints into ArrayList

    
using  System;
using  System.Collections;

class  MainClass
{
    static  void  Main(string[]  args)
    {        
        ArrayList  myInts  =  new  ArrayList();
        myInts.Add(8);
        myInts.Add(3);
        myInts.Add(9);

        //  Unbox  first  item.
        int  firstItem  =  (int)myInts[0];

        //  Another  boxing  operation!
        Console.WriteLine("First  item  is  {0}",  firstItem);
    }
}
