C#中結構struct的使用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Demo
{
    enum orientation:byte
    {
        北 = 1,
        南 = 2,
        東 = 3,
        西 = 4
    }

    struct route
    {
        public orientation direction;
        public double distance;
    }
    class Program
    {
        static void Main(string[] args)
        {
            route myRoute;
            int myDirection = -1;
            double myDistance;
            Console.WriteLine("1)北\n 2)南\n 3)東\n 4)西\n");
            do
            {
                Console.WriteLine("選擇一個方向:");
                myDirection = Convert.ToInt16(Console.ReadLine());
            } while (myDirection < 1 || myDirection > 4);

            Console.WriteLine("輸入一個距離:");
            myDistance = Convert.ToDouble(Console.ReadLine());

            myRoute.direction = (orientation)myDirection;
            myRoute.distance =  myDistance;

            Console.WriteLine("方向是{0},距離是{1}!",myRoute.direction,myRoute.distance);

            Console.ReadKey();
        }
    }
}

結構比枚舉更復雜，可以保存多種類型的數據！
