使用C#写一个基本类

标签：partial   小学生   sch   data   构造   中学   extc   ring   forms   

1. 设计一个Windows应用程序，在该程序中首先构造一个学生基本类，在分别构造小学生、中学生、中职生、大学生等派生类，要求具有不同的特征和行为，能通过静态成员自动记录不同的学生人数。

 

参考界面如下：

 

 

（1）修改一些控件的属性。

（2）核心代码如下：

  using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

 

namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        public class Student

        {

            private String Name;

            private String Sex;

            private StringSchool;

            private String Grade;

 

 

            public String SName

            {

                get { return Name; }

                set { Name = value; }

            }

            public String SSex

            {

                get { return Sex; }

                set { Sex = value; }

            }

            public String SSchool

            {

                get { return School; }

                set { School = value; }

            }

            public String SGread

            }

 

        }
