C#enum枚举

  枚举：把有限的元素放在一起。使用字母代替数字标示的含义。枚举是一个值类型。

现在练习一下：

using System;

public enum Seasons{spring,summer,autumn=6,winter}

public  enum Weekday{one,two,three,four,five,six,seven}

 public class studyEnum

 {

	 public static void Main()

	 {

	    Seasons s = Seasons.spring;

		Console.WriteLine(s);

		Seasons a = Seasons.summer;

		 Console.WriteLine((int)a);

		Seasons b = Seasons.autumn;

		Console.WriteLine((int)b);

		Seasons c = Seasons.winter;

		 Console.WriteLine((int)c);

		 Weekday w = Weekday.four;

		 Console.WriteLine(w);

		 Weekday t = Weekday.six;

		 Console.WriteLine((int)t);

	 }

 }
