C# 工资结算系统-类继承

---

（一）阐述

1. 普通员工：Employee固定月薪。
2. 销售员：Salesman固定月薪+销售额*提成率。
3. 计时工人：HourlyWorker固定月薪+工作小时数每小时酬金（每月超过160小时，酬金1.5倍)
4. 计件工人：固定月薪+每件酬金*生产的产品件数。

（二）截图

1. 添加员工
   员工号由程序自动提供，添加员工需要输入姓名和工种。
   
   同样依次输入员工信息。

2. 计算并输出每月工人工资
   通过ID对于对应的员工输入对应信息：

   • 对于普通员工直接输出工资信息
   • 对于销售员输入销售额
   • 对于计时工输入工时，并体现激励机制
   • 对于计件工输入生产数
     

3. 查询单个员工本月工资
   
   其它类同。

4. 打印所有员工工资
