枚举型Enum和结构型Stuct

枚举型实质就是使用符号来表示的一组相互关联的数据.

Season currentSeason,nextSeason;
currentSeason = Season.Spring;
nextSeason = currentSeason + ;
Console.WriteLine("当前季节为：{0},{1}",int)currentSeason,currentSeason);

Console.WriteLine("下一个季节为：{0}",nextSeason);

Console.ReadKey(true);        

 public enum Season
{
            Spring = ,
            Summer,
            Autumn = ,
            Winter,

} 

结构体用来描述一组相互关联的数据，用这些数据共同来描述一个完整事物。

Student stu;
stu.stu_no = ;
stu.stu_name = "陈";
stu.age = ;
stu.sex = "男";
Console.WriteLine("姓名：{0}",stu.stu_name);
Console.WriteLine("学号：{0}",stu.stu_no);
Console.WriteLine("年龄：{0}",stu.age);            
Console.WriteLine("性别：{0}",stu.sex);

struct Student
{
      public int stu_no;
      public string stu_name;
      public int age;
      public string sex;
}
