请教！枚举和结构的一个案例问题，
using System;
using System.Collections.Generic;
using System.Text;
namespace 结构案例
{
enum orientation : byte //定义orientation枚举
{
north = 1,
south = 2,
east = 3,
west = 4,
}
struct route //定义了结构
{
public orientation direction; //通过关键字 public 定义了枚举新的变量
public double distance; //定义double 变量
}
class Program
{
static void Main(string[] args)
{
route myRoute; //结构定义新变量
int myDirection = -1;
double myDistance;
Console.WriteLine("1> North\n 2> South\n 3> East\n 4>West");
do
{
Console.WriteLine("select a direction:");
myDirection = Convert.ToInt32(Console.ReadLine());//转换类型
} while ((myDirection < 1) || (myDirection > 4));
Console.WriteLine("input a distance;");
myDistance = Convert.ToDouble(Console.ReadLine());//转换类型
myRoute.direction = (orientation)myDirection;
myRoute.distance = myDistance;
Console.WriteLine(" myRoute specifies a direction of{0} and a" +
"distance of {1}", myRoute.direction, myRoute.distance);
Console.ReadKey();
}
}
}
