用C# 编写一个员工工资计算
请用C#编写一个工资计算Console App：需要读取一个.txt文件里的员工信息然后计算出相关实付工资（扣除个人所得税和养老金）。这是根据国外一个公司的需要，员工是年薪制，但是工资是按每两周发放一次。
- txt文件里的员工信息如下：
| 员工编号 | 员工姓 | 员工名 | 年薪 | 扣除养老金比例 |
3 ， Zhang ， San ， 60000 ， 4%
4 ， Li ， Si ，45000 ， 0%
5 ， Wang ， Fei ， 55000 ， 3%
（个人所得税比例：年收入48000 以内：17.5%；年收入48000至70000: 30%；年收入70000以上：33%）
- 要求：读取.txt文字信息，然后在屏幕显示计算结果
（1）计算出员工时薪 (公式：年薪 / 52周每年 / 40小时每周 ) ：
（2）实付工资（公式：工资 - 养老金 - 税）：
3.要求：程序需要有的几个功能：
1.能根据员工 ID 显示所有员工实付工资
2.保存计算后的每两周实付工资信息为.txt格式文件
3.输入员工 ID 能查找员工个人信息和工资信息
4.运行程序时屏幕显示如下操作选项供用户选择：
（1）计算每两周工资
（2) 显示员工信息
（3）输入一个员工编号能查找员工信息
（4）保存信息到.txt文档
(5) 退出
5.要求每次用户选择以上一个功能时显示结果，并再次显示操作选项让客户选择，只有客户退出功能程序才会关闭。
如果对你有启发，可以点点采纳，谢谢

使用java可以吗？
这直接用excel就很方便了
console实现，可以说一下细节。
这个问题中没有强调使用界面，更多的是使用doc显示，感觉更好的是用C/C++去实现，比较好吧

我这个写法就很粗浅，楼上的大哥写法比较正规，拓展性也比较强。
