C# 体检套餐管理系统

 1.创建体检项目维护系统中的检查项目类 ,体检套餐类和一个泛型类如下图

 

 2.窗体的搭建,如下图:

                       

   3.编写代码:

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace _05_体检套餐{    public partial class FrmMain : Form    {        public FrmMain()        {            InitializeComponent();
