C#编写代码修改

// C#面向对象程序设计编程实例
//要求：请给学校教务管理系统设计一个教师类和学生类，其中，教师信息包括教师编号，教师姓名，年龄（0-80）、工资（工资>5000，税收为百分10，<2000税收为0，中间的为百分5）和所属学院；学生信息包括学号，学生姓名、年龄（0-60），所属班级和总成绩。
//然后，尝试引入一个基类，并使用基类来简化设计。并编写程序调试验证。

追问：不能在我的基础上修改么？

答案：using System.Collections.Generic;

namespace WindowsApplication1
{
    class Cool
    {
        private int no;
        private string name;
        private int age;

        public Cool(int no, string name, int age)

            }
            set

        }

        public class teacher : Cool
        {
            double w;
            double wages;
            int age;
            public teacher(int id, string name)
                : base(id, name,0)
            {
                if (0 < age && age < 80)
                {
                }
                else
                {
                    Console.Write("请输入0到80的年龄");
                }
                w = wages;
                if (wages >= 5000)
                    w = wages * 0.9;
                else if (wages > 2000 & wages < 5000)
                    w = wages * 0.95;
              

            }
            public class student : Cool
            {
                int age;
                int sclass;
                float score;
                public student(int id, string name)
                    : base(id, name,0)
                {
                    if (0 < age && age < 60)
                    {

                    }

                    else
                    {
                        Console.Write("请输入0到60的年龄");
                    }
                    Console.Write("请输入班级");
                    sclass = Console.Read();
                    Console.Write("请输入成绩");
                    score = Console.Read();
                }

            }


        }
        static void Main(string[] args)
        {
            string w;
            Console.Write("输入学生信息请按1，输入教师信息请按2");
            w = Console.ReadLine();
            switch (w)
            {
                case "1": new WindowsApplication1.Cool.teacher.student(0,""); break;
                case "2": new teacher(0, ""); break;
            }

            Console.ReadLine();
        }
    }
}

分值太少了吧。这个类好麻烦
public Cool(int no, string name, int age)
{this.no = no;
this.name = name;
this.age = age;

Console.Write("请输入号码");
no= Console.Read();
Console.Write("请输入姓名");
name = Console.Read();
Console.Write("请输入年龄");
age = Console.Read();
}
这里错了
