// Order.cs - shows the order in which constructors and destructors
// are called in a C# program.
//
// Compile this program with the following command line:
// C:>csc Order.cs
//
namespace nsOrder
{
using System;

static public void Main ()

// Declare a base class and have its constructor and destructors
// print messages.

{

// print messages.

// print messages as well.
