体检套餐管理系统
1.任务描述
1.加载默认体检套餐
2.维护体检套餐
维护功能主要有以下几个方面
1.显示指定套餐的项目明细
2.向指定套餐添加检查项目信息
3.删除套餐中的项目信息
4.新建套餐
2.实现代码
1.搭建体检套餐管理系统的主窗体
2.创建体检套餐项目维护中的检查项目类，体检套餐类
3.系统默认提供一种套餐“入学套餐”填充检查项目对象到窗体
1 //套餐类 2 public class HealthCheckSet 3 { 4 private string name; 5 6 public string Name 7 { 8 get { return name; } 9 set { name = value; }10 }11 12 private int price;13 14 public int Price15 {16 get { return price; }17 set { price = value; }18 }19 20 private Dictionary item;21 22 public Dictionary Item23 {24 get { return item; }25 set { item = value; }26 }27 28 public HealthCheckSet() 29 {30 item = new Dictionary ();31 }32 33 public HealthCheckSet(string name,Dictionary item) 34 {35 this.Name = name;36 this.Item = item;37 }38 39 public void GetPrice() 40 {41 int sum = 0;42 foreach (HealthCheckItem i in item.Values)43 {44 sum += i.Price;45 }46 this.price = sum;47 }48 }
1 //项目类 2 public class HealthCheckItem 3 { 4 private string name; 5 6 public string Name 7 { 8 get { return name; } 9 set { name = value; }10 }11 private int price;12 13 public int Price14 {15 get { return price; }16 set { price = value; }17 }18 private string description;19 20 public string Description21 {22 get { return description; }23 set { description = value; }24 }25 public HealthCheckItem(string name, int price, string description) 26 {27 this.Name = name;28 this.Price = price;29 this.Description = description;30 }31 }
1 //窗体中主要实现代码 2 public frmMain() 3 { 4 InitializeComponent(); 5 } 6 //用于保存单个项目 7 HealthCheckItem h1, h2, h3, h4, h5, h6, h7, h8; 8 //单个项目集合 9 Dictionary allItem = new Dictionary ();10 //一个套餐所包含的项目11 Dictionary items = new Dictionary (); 12 //套餐集合13 Dictionary allSet = new Dictionary ();14 //定义一个初始化套餐15 HealthCheckSet set;16 //向初始化的套餐添加各个项目17 public void GetItems() 18 {19 h1 = new HealthCheckItem("身高",5,"用于检查身高");20 h2 = new HealthCheckItem("体重", 5, "用于检查体重");21 h3 = new HealthCheckItem("视力", 5, "用于检查视力");22 h4 = new HealthCheckItem("听力", 5, "用于检查听力");23 h5 = new HealthCheckItem("B超", 30, "用于检查B超");24 h6 = new HealthCheckItem("肝功能", 30, "用于检查肝功能");25 h7 = new HealthCheckItem("心电图", 50, "用于检查心电图");26 h8 = new HealthCheckItem("血常规", 50, "用于检查血常规");27 allItem.Add(h1.Name, h1);28 allItem.Add(h2.Name, h2);29 allItem.Add(h3.Name, h3);30 allItem.Add(h4.Name, h4);31 allItem.Add(h5.Name, h5);32 allItem.Add(h6.Name, h6);33 allItem.Add(h7.Name, h7);34 allItem.Add(h8.Name, h8);35 36 }37 //添加一个套餐38 public void GetSet() 39 {40 items.Add(h1.Name,h1);41 items.Add(h3.Name, h3);42 items.Add(h4.Name, h4);43 set = new HealthCheckSet("入学体检",items);44 set.GetPrice();45 allSet.Add("入学体检",set);46 }47 //绑定下拉框 48 public void GetCbo() 49 {50 cboSetList.Items.Clear();51 cboSetList.Items.Add("请选择");52 foreach (string a in allSet.Keys)53 {54 cboSetList.Items.Add(a);55 }56 this.cboSetList.SelectedIndex = 0;57 58 cbolitemsList.Items.Clear();59 cbolitemsList.Items.Add("请选择");60 foreach (string a in allItem.Keys)61 {62 cbolitemsList.Items.Add(a);63 }64 this.cbolitemsList.SelectedIndex = 0;65 }66 //窗体加载时调用各个方法67 private void frmMain_Load(object sender, EventArgs e)68 {69 70 GetItems();71 GetSet();72 GetCbo();73 }
实现效果：
4.实现删除体检套餐信息
//删除 private void btnDelete_Click(object sender, EventArgs e) { string name = this.dgvList.SelectedRows[0].Cells[0].Value.ToString(); string Setname = this.cboSetList.Text; MessageBox.Show(string.Format("确定要删除"+name+"这一项吗？","提示")); allSet[Setname].Item.Remove(name); UpdateSet(allSet[Setname]); } 实现效果：
5.向套餐中添加检查项目
//向套餐中添加项目 private void btnItemAdd_Click(object sender, EventArgs e) { if(this.cbolitemsList.SelectedIndex==0) { MessageBox.Show("请选择要添加的项目"); return; } string name=this.cboSetList.Text; if(name=="请选择") { MessageBox.Show("请选择套餐"); return; } if (!allSet[name].Item.Keys.ToList().Contains(this.cbolitemsList.Text)) { allSet[name].Item.Add(this.cbolitemsList.Text, allItem[this.cbolitemsList.Text]); this.lblName.Text = name; GetPrice(); UpdateSet(allSet[name]); } else { MessageBox.Show("已有该项目"); } } 实现效果：
6.新建套餐
1 //添加套餐 2 private void btnSetAdd_Click(object sender, EventArgs e) 3 { 4 string setName=this.txtSetName.Text; 5 if (this.txtSetName.Text.Trim() != null && this.txtSetName.Text.Trim() != "") 6 { 7 HealthCheckSet set = new HealthCheckSet(); 8 allSet.Add(txtSetName.Text, set); 9 GetCbo();10 this.cboSetList.SelectedIndex = allSet.Count();11 }12 else 13 {14 MessageBox.Show("请输入套餐名称");15 }16 }17 //下拉框中套餐名字改变时DataGridView里面所绑定的项目也改变18 private void cboSetList_SelectedIndexChanged(object sender, EventArgs e)19 {20 string name = this.cboSetList.Text;21 if (name == "请选择")22 {23 this.dgvList.DataSource = new BindingList ();24 this.lblName.Text = "";25 this.lblPrice.Text = "";26 return;27 }28 this.lblName.Text = name;29 GetPrice();30 UpdateSet(allSet[name]);31 } 实现效果：
