C#实现抽象类的继承

1. 设计编写一个控制台应用程序，练习类的继承。

(1) 编写一个抽象类 People，具有”姓名”，”年龄”字段，”姓名”属性，Work 方法。

(2) 由抽象类 People 派生出学生类 Student 和职工类 Employer，继承 People 类，并

覆盖Work 方法。

(3) 派生类 Student 增加”学校”字段，派生类 Employer 增加”工作单位”字段。

(4) 在 Student 和 Employer 实例中输出各自不同的信息。

            employer b = new employer("李来", 45, "教务处");

            b.work();
