      Console.WriteLine(BitConverter.ToBoolean(b,0));
      // Convert an int to a byte array and display.
      b = BitConverter.GetBytes(1234);
      Console.WriteLine(BitConverter.ToString(b));
      // Convert a byte array to an int and display.
      Console.WriteLine(BitConverter.ToInt32(b,0));
      // Convert a decimal to a byte array and display.
