(2)我的订单页面-查询
(3)退票
2、核心源码:
（1）我的订单页面前台效果
（2）我的订单页面前台代码

（3）我的订单页面后台代码（显示用户所有车票信息）
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { BindGv(); } } protected void BindGv() { Userinfo user = (Userinfo)Session["user"]; int uid = user.Uid; DataSet ds = bll.SelectInfoByUid(uid); this.GridView1.DataSource = ds; this.GridView1.DataBind(); } DAL层： public DataSet SelectInfoByUid(int uid) { string sql = $"select * from Orderinfo inner join Carinfo on Orderinfo.Cid=Carinfo.Cid where Uid={uid}"; DataSet ds = dbHelper.GetData(sql); return ds; }
（1）我的订单页面查询功能前台页面效果图
（2）我的订单页面查询功能后台代码
protected void btnSelect_Click(object sender, EventArgs e) { //从前台获取数据 //出发地 string cfd = this.txtCfd.Text; //目的地 string mdd = this.txtMdd.Text; string date = DateTime.MinValue.ToString(); if (this.test1.Text != "") { //出发日期 date = this.test1.Text; } Userinfo user = (Userinfo)Session["user"]; int uid = user.Uid; DataSet ds = bll.SelectInfoByUid(uid, cfd, mdd, date); this.GridView1.DataSource = ds; this.GridView1.DataBind(); } DAL层： public DataSet SelectInfoByUid(int uid, string beginSta, string endSta, string date) { string sql = $"select * from Orderinfo inner join Carinfo on Orderinfo.Cid=Carinfo.Cid where Uid={uid} and 1=1 "; if (beginSta != "") { sql += $"and Begin_sta ='{beginSta}'"; } if (endSta != "") { sql += $"and End_sta='{endSta}'"; } if (date != DateTime.MinValue.ToString()) { sql += $"and Start_date='{date}'"; } DataSet ds = dbHelper.GetData(sql); return ds; }
（1）我的订单页面退票功能后台代码
/// <summary> /// 退票 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { int oid = Convert.ToInt32(this.GridView1.DataKeys[e.RowIndex].Value); bool boo= bll.Del(oid); if (boo) { BindGv(); } else { Response.Write("<script>alert('退票失败！！！')</script>"); } } DAL层： public bool Del(int oid) { string sql = $"delete from Orderinfo where Oid={oid}"; int num=dbHelper.ExecuteNonQuery(sql); if (num!=0) { return true; } else { return false; } }
3、遇到的问题:
(1)显示我的订单页面刚开始没有考虑周全，显示的是订单表中所有信息
(2)很多想实现的效果因为能力有限没办法实现，需要前端技术
4、解决的方法:
(1)根据之前买票经历重新完善功能
(2)技术能力方面需要利用这个暑假做提升
