1.2:多态与重写
重写,子类override,父类virtual,
用数组输出两个show,多态
Person[] persons = new Person[2];
Student stu = new Student("aaa", 20, true);
Teacher t = new Teacher("aa", 12, false);
persons[0] = stu;
persons[1] = t;
for (int i = 0; i < persons.Length; i++)
{
persons[i].show();
}
Console.ReadKey();
如果子类没有override 数组输出的是父类的show
//Person p = new Student();
