详细说明：
特别说明请注意： 根许多网友反应， using Maticsoft.Functions; 这些代码看不懂 其实Functions 这个dll是我定义常用的函数类，如果需要跟我联系索取http://sql8.net 下面有我的群号， 其中 ArtsShop.Model.Arts_Product _p = new ArtsShop.Model.Arts_Product(); ArtsShop.BLL.Arts_Product p = new ArtsShop.BLL.Arts_Product(); _p = p.GetModel(id); 这是我的商品信息的类，三层结构，这个在用时你们只能换成你们自己的，这些代码完全可以删除， 比如 MyDr[1] = _p.Title; 用来读取商品名的，你们可以改MyDr[1] = dr["productname"].ToString();就行了， AddToCart.aspx页面代码 <%@ Page Language="C#" AutoEvent Wireup="true" CodeFile="AddToCart.aspx.cs" Inherits="AddToCart" %> 无标题页 AddToCart.aspx.cs页面代码 using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using Maticsoft.Functions;public partial class AddToCart : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { int ProID; HttpCookie cookie; bool Tempbl = false; string Tempstr; if (!Page.IsPostBack) { if (!object.Equals(Request.QueryString["id"], null)) { ProID = int.Parse(Request.QueryString["id"]); //创购物车cookie yxy .//sql8.net if (object.Equals(Request.Cookies["ztbscart"], null)) cookie = new HttpCookie("ztbscart"); else cookie = Request.Cookies["ztbscart"]; //判断是否已存在于购物车内 yxy // sql8.net for (int i = 0; i < cookie.Values.Keys.Count; i++) { if (!object.Equals(cookie.Values.Keys[i], null)) { Tempstr = cookie.Values.AllKeys[i].ToString(); if (Tempstr.Trim() != "") { if (ProID == int.Parse(cookie.Values.AllKeys[i])) { Tempbl = true; break; } } } } //不未购买过则加入购物车 yxy //sql8.net if (!Tempbl) cookie.Values.Add(ProID.ToString(), "1"); else { } TimeSpan ts = new TimeSpan(0, 0, 10, 0); cookie.Expires = DateTime.Now + ts; Response.AppendCookie(cookie); } BindGrid(); } } //绑定数据 yxy //sql8.net private void BindGrid() { DataTable MyDt; DataRow MyDr; string str = ""; MyDt = new DataTable(); MyDt.Columns.Add(new DataColumn("id", str.GetType())); MyDt.Columns.Add(new DataColumn("Title", str.GetType())); MyDt.Columns.Add(new DataColumn("Num", str.GetType())); MyDt.Columns.Add(new DataColumn("Price", str.GetType())); MyDt.Columns.Add(new DataColumn("Discount", str.GetType())); MyDt.Columns.Add(new DataColumn("Vipprice", str.GetType())); MyDt.Columns.Add(new DataColumn("Totle", str.GetType())); if (!object.Equals(Request.Cookies["ztbscart"], null)) { HttpCookie cookie = Request.Cookies["ztbscart"]; double Totle; //Response.Write("|" + Request.Cookies["ztbscart"].Values.Keys[1].ToString() + "|"); //Response.End(); for (int i = 0; i < cookie.Values.Keys.Count; i++) { int id; MyDr = MyDt.NewRow(); if (cookie.Values.AllKeys[i] != "" && cookie.Values[i] != "") { id = int.Parse(cookie.Values.AllKeys[i].ToString()); ArtsShop.Model.Arts_Product _p = new ArtsShop.Model.Arts_Product(); ArtsShop.BLL.Arts_Product p = new ArtsShop.BLL.Arts_Product(); _p = p.GetModel(id); MyDr[0] = id; MyDr[1] = _p.Title; MyDr[2] = cookie.Values[i]; MyDr[3] = _p.Price; MyDr[4] = _p.Discount; MyDr[5] = _p.Vipprice1; Totle = double.Parse(MyDr[2].ToString()) * double.Parse(MyDr[5].ToString()); MyDr[6] = Totle; MyDt.Rows.Add(MyDr); } } GridView1.DataSource = MyDt.DefaultView; GridView1.DataBind(); } } protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { //编辑某行数量 yxy //sql8.net GridView1.EditIndex = e.NewEditIndex; BindGrid(); } protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e) { //取消更新 yxy //sql8.net GridView1.EditIndex = -1; BindGrid(); } protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { //更新数量 yxy //sql8.net string num; TextBox tempbx = new TextBox(); Label templb = new Label(); tempbx = (TextBox)(GridView1.Rows[e.RowIndex].Cells[6]).Controls[1]; num = tempbx.Text.ToString(); HttpCookie cookie = new HttpCookie("ztbscart"); for (int i = 0; i < GridView1.Rows.Count; i++) { string id; string tempnum; id = GridView1.Rows[i].Cells[1].Text.ToString(); if (e.RowIndex == i) tempnum = num; else { templb = (Label)(GridView1.Rows[i].Cells[6]).Controls[1]; tempnum = templb.Text.ToString(); } if (tempnum.Trim() == "") tempnum = "0"; //Response.Write("ID:"+id.ToString() + "Num:"+tempnum+":"+i+"
