asp.net的session对象购物车

问题描述

asp.net的session对象购物车

我刚学asp.net，要做购物车，不用数据库的那种，只是session对象，现在代码写好了，就是我第二次点击购买的时候，我希望购物车里有两次记录要怎么做，就比如同一件商品，我点击两次购买，购物车里有两个订单
代码如下：
<%@ Page Language="C#" %>

protected void Button1_Click(object sender, EventArgs e)
{
Session["a"] = Label1.Text;
Session["g"] = Label7.Text +1 +"";

Response.Redirect("~/Default2.aspx");
}

protected void Button2_Click(object sender, EventArgs e)
{
Session["b"] = Label2.Text;
Session["h"] = Label8.Text +"";
Response.Redirect("~/Default2.aspx");
}

protected void Button3_Click(object sender, EventArgs e)
{
Session["c"] = Label3.Text;
Session["i"] = Label9.Text +"";
Response.Redirect("~/Default2.aspx");
}

protected void Button4_Click(object sender, EventArgs e)
{
Session["d"] = Label4.Text;
Session["j"] = Label10.Text +"";
Response.Redirect("~/Default2.aspx");
}

protected void Button5_Click(object sender, EventArgs e)
{
Session["e"] = Label5.Text;
Session["k"] = Label11.Text +"";
Response.Redirect("~/Default2.aspx");
}

protected void Button6_Click(object sender, EventArgs e)
{
Session["f"] = Label6.Text;
Session["l"] = Label12.Text +"";
Response.Redirect("~/Default2.aspx");
}

继续购物/asp:LinkButton

要怎么做呢？

解决方案

你可以点击购买这个按钮以后创建一个
HashTable shopping = new HashTable();
点击购买后往shopping.add("商品ID",商品对象);
每次点击都往这个shopping对象中添加一条记录 ,添加完以后把Session["Shop"] = shopping ;展示就直接把Sessiong["Shop"]对象中的Table强转一下就好了 !
