  static void Main() {

    ArrayList inv = new ArrayList();

    // Add elements to the list.

    inv.Add(new Inventory("Pliers", 5.95, 3));

    inv.Add(new Inventory("Wrenches", 8.29, 2));

    inv.Add(new Inventory("Hammers", 3.50, 4));

    inv.Add(new Inventory("Drills", 19.88, 8));

    Console.WriteLine("Inventory list before sorting:");

    foreach(Inventory i in inv) {

      Console.WriteLine("   " + i);

    }

    Console.WriteLine();

    // Sort the list.

    inv.Sort();

    Console.WriteLine("Inventory list after sorting:");

    foreach(Inventory i in inv) {

      Console.WriteLine("   " + i);

    }

  }

}

Here is the output. Notice that after the call to 

Sort( )

, the inventory is sorted by name.

Inventory list before sorting:

   Pliers    Cost:  $5.95  On hand: 3

   Wrenches  Cost:  $8.29  On hand: 2

   Hammers   Cost:  $3.50  On hand: 4

   Drills    Cost: $19.88  On hand: 8

Inventory list after sorting:

   Drills    Cost: $19.88  On hand: 8

   Hammers   Cost:  $3.50  On hand: 4

   Pliers    Cost:  $5.95  On hand: 3

   Wrenches  Cost:  $8.29  On hand: 2
