实验报告姓名： 孟凡响 学号： 115767 日期： 2014-01-02 实验名称： 实验一 继承与多态编程练习 成绩： 一、实验目的及要求实验目的1理解面向对象思想，体会面向对象思想在编程中的应用。2掌握Visual C#.NET类的创建（成员，方法，属性），类的继承，类的多态性及类的方法的重载。3. 理解继承的含义，掌握派生类的定义方法和实现；4. 编写体现类的继承性（成员变量，成员方法，成员变量隐藏）的程序；5. 编写体现类多态性（成员方法重载，构造方法重载）的程序。实验要求1. 写出程序，并调试程序，要给出测试数据和实验结果。2. 整理上机步骤，总结经验和体会。3. 完成实验日志和上交程序。二、实验环境Windows XP操作系统，Visual 2005三、实验源程序及关键代码解释Using指令集：using System;using System.Collections.Generic;using System.Text;定义Employee类public class Employee protected string name; private string sexy; private int salary; private string date; private string department; private string telnum; public Employee() public Employee(string args) name = args 0; sexy = args 1; salary = Convert.ToInt32 (args 2); date = args 3; department = args4 ; telnum = args 5; /virtual关键字,方法可以重写 public virtual void Display() Console.WriteLine(Name:0, name); Console.WriteLine(Sexy:0, sexy); Console.WriteLine(Salary:0, salary); Console.WriteLine(Date:0, date); Console.WriteLine(Department:0, department); Console.WriteLine(Telephone:0, telnum); 定义Employer类，继承基类Employeepublic class Employer:Employee private string position; private string promote_date; private string number; private string Ename=new string 50; public Employer(string args): base(args) position = args6; promote_date = args7; number = args8; for (int i = 0; i Convert.ToInt32(number); i+) Enamei = args9 + i; /重写基类的Display的方法 public override void Display() base.Display(); Console.WriteLine(Position:0, position); Console.WriteLine(Promote_date:0, promote_date); Console.WriteLine(Number of employee:0, number); for (int i = 0; i Convert.ToInt32 (number) ; i+) Console.WriteLine(Name of employee0:1,i+1, Enamei); Main函数调用Employee和Employer的构造函数和方法并显示：public class Class1 static void Main(string args) Console.WriteLine(-软件051-孔令民-051023-); string employee1=new string 50; Console.WriteLine(Please input imformation of employee:); Console.WriteLine(name,sexy,salary,date,department,telephonenumber); employee1 = Console.ReadLine().Split( ); /调用Employee构造函数 Employee newEmployee = new Employee(employee1); Console.WriteLine(-This is the imfomation of employee:-);/调用Employee Display()方法显示数据 newEmployee.Display(); Console.WriteLine(-); Console.WriteLine(Please input imformation of employer:); Console.WriteLine(name,sexy,salary,date,department,telephonenumber,position,promote_date,number of employees,name of employees(name1 name2 name3 .); employee1 = Console.ReadLine().Split( ); /调用Employer构造函数 Employer newEmployer = new Employer(employee1); Console.WriteLine(
