利用对象序列化将购物车保存在Cookie中
最近做一个购物类网站，正好在学习对象序列化，于是突然奇想，想把购物车对象(里面已经封装了很多购物车的常用方法)序列化后，将序列化后的字符串保存在Cookie中，需要时，现从Cookie中取出该字符串，反序列化为购物车对象
主要代码如下：
购物车类ShopCart.cs：
----------------------------------------------------------------
using System;
using System.Collections;
/// <summary>
/// 购物车类
/// </summary>
[Serializable]
public class ShopCart
{
...详细内容见附件
}
以下是调用页面：
Demo.aspx
---------------------------------------------------
<%@ Page Language= "C# " AutoEventWireup= "true " CodeFile= "Demo.aspx.cs " Inherits= "Public_Test_Demo " %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN " "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html xmlns= "http://www.w3.org/1999/xhtml " >
<head runat= "server ">
<title> 无标题页 </title>
</head>
<body>
<form id= "form1 " runat= "server ">
<div>
<asp:GridView ID= "GridView1 " runat= "server ">
</asp:GridView>
<br/>
<asp:Button ID= "btnReadCookie " runat= "server " Text= "读取Cookie中的ShopCart " OnClick= "btnReadCookie_Click " /> </div>
</form>
</body>
</html>
--------------------------------------------
Code-behind端代码:Demo.aspx.cs
--------------------------------------------
using System;
using System.Collections;
using System.Web;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
using System.Text;
public partial class Public_Test_Demo : System.Web.UI.Page
{
string CookieName = "ShopCart ";
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ShopCart SC = new ShopCart();
SC.AddItem( "1 ", "ProductName ", "ProductName ", 0, 0, "ProductID ", " ", 0, 0, 0, 0, "ShopId ", "TestUrl ", true);
