体检套餐系统
项目总结
此类为HealthCheckItem（检查项目）类
//HealthCheckItem类 //作用是检查项目 private int price; //检查项目的价格 private string description; //检查项目的描述 private string name; //检查项目的名称 public string Name { get { return name; } set { name = value; } } public string Description { get { return description; } set { description = value; } } public int Price { get { return price; } set { price = value; } } public HealthCheckItem(string name, int price, string description) { this.Name = name; this.Description = description; this.Price = price; }
此类为套餐类TaoCan（体检套餐）
public class TaoCan //体检套餐类 { private int price; //套餐总价格 private List<HealthCheckItem> items; //套餐集合 private string name; //套餐名称 public TaoCan() { items = new List<HealthCheckItem>(); } public TaoCan(string name, List<HealthCheckItem> items) { this.Name = name; this.items = items; } public string Name { get { return name; } set { name = value; } } public List<HealthCheckItem> Items { get { return items; } set { items = value; } } public int Price { get { return price; } set { price = value; } } public void CalcPrice() { int totalPrice = 0; foreach (HealthCheckItem item in items) { totalPrice += item.Price; } this.price = totalPrice; } }
