枚舉是一個(gè)特定的常量集合組成的獨(dú)特類(lèi)型
using System;
public enum TimeOfDay
{
?? Morning = 0,
?? Afternoon = 1,
?? Evening?
}
class EnumExample
{
?? public static int Main()
?? {
//調(diào)用方法
????? WriteGreeting(TimeOfDay.Morning);
//獲取枚舉字符串
??? TimeOfDay time = TimeOfDay.Afternoon;
??? Console.WriteLine(time.ToString());
//獲取枚舉字符串的值
??? TimeOfDay time2 = (TimeOfDay) Enum.Parse(typeof(TimeOfDay), "Evening", true);
? ? Console.WriteLine((int)time2);
// 遍歷所有的枚舉元素
??? Type time3=typeof(TimeOfDay);
??? foreach(string s in Enum.GetNames(time3))
??? {
??? Console.WriteLine(s);
??? }
? ? ? return 0;
?}?

?? static void WriteGreeting(TimeOfDay timeOfDay)

?? {
????? switch(timeOfDay)
????? {
???????? case TimeOfDay.Morning:
??????????? Console.WriteLine("Good morning!");
??????????? break;
