C#新手，跪求大神注释以下代码，十万火急

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace EnumTypeEX02
{
enum Orientation : byte
{
North = 1,
South = 2,
East = 3,
West = 4
}
class Program
{
static void Main(string[] args)
{
// Code for Step 1
Orientation myDirection = Orientation.North;
Console.WriteLine("myDirection = {0}", myDirection);
Console.ReadKey();
//// Code for Step 2
//byte directionByte;
//string directionString;
//Orientation myDirection = Orientation.North;
//Console.WriteLine("myDirection = {0}", myDirection);
//directionByte = (byte)myDirection;
//directionString = Convert.ToString(myDirection);
//Console.WriteLine("byte equivalent = {0}", directionByte);
//Console.WriteLine("string equivalent = {0}", directionString);
//Console.ReadKey();
}
}
}
