通用学生信息管理系统-C#结业报告院系：计算机科学与工程班级：140402姓名：周琳学号：20141180一、问题提出：1.创建相应的成员变量保存学生基本信息。2.创建相应属性和索引以实现对成员变量访问的封装。3.创建相应的方法以实现对学生基本信息的管理。 4.创建相应的方法以实现对学生成绩的管理。5.派生出小学生，中学生，大学生等子类。二、问题分析： 1、添加基类Student，定义私有成员变量姓名，性别，号，民族，住址，英语，数学，语文等学生的基本信息并创建相应的属性实现对成员变量访问的封装。 2、分别定义派生类Pupil，CollegeStudenr，Middleschoolstudent，并使用base关键字调用基类构造函数。 3、添加Option类实现对学生信息进行的一系列操作。 4、添加Manager类实现管理用户登陆。三、程序代码：Student.cs:using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace StudentInformation public class Student private string studentType;
