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();}private List<HealthCheckItem> checkItems = new List<HealthCheckItem>();public List<HealthCheckItem> CheckItems{get { return checkItems; }set { checkItems = value; }}// 创建套餐类表的集合private List<HealthCheckSet> checkSets = new List<HealthCheckSet>();public List<HealthCheckSet> CheckSets{get { return checkSets; }set { checkSets = value; }}// 初始化检查项目信息public void IntitalHealthCheckItem(){//创建检查项目的对象HealthCheckItem healthCheckItem1 = new HealthCheckItem();healthCheckItem1.Name =
