Penson类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Json_Demo
{
    public class Penson
    {
        private string _name;
        private int _age;
        private string _address;

        public string Address
        {
            get { return _address; }
            set { _address = value; }
        }

        public int Age
        {
            get { return _age; }
            set {
                if (_age < 100 && _age > 0)
                {
                    _age = value;
                }
                else
                {
                    _age = 0;
                }
            }
        }

        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }
    }
}

后台代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
//引入相关命名空间
using System.Web.Script;
using System.Web.Script.Serialization;

namespace Json_Demo
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Penson p1 = new Penson();
            p1.Name = "JSON";
            p1.Age = 120;
            p1.Address = "江西高安";
            
            JavaScriptSerializer json1 = new JavaScriptSerializer();
            string str = json1.Serialize(p1);//JSON序列化
            Session["str1"] = str;//session页面传值
        }
    }
}

前台

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Json_Demo.WebForm1" %>
//导入命名空间
<%@ Import Namespace="Json_Demo" %>
<%@ Import Namespace="System.Web.Script.Serialization" %>
<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <% string s = (string)Session["str1"];
               Response.Write(s);%>
            <br />
            <% Penson p1 = new Penson();
               JavaScriptSerializer str2 = new JavaScriptSerializer();
               //JSON反序列化
               p1 = str2.Deserialize<Penson>(s);
               Response.Write(p1.Name + p1.Age + p1.Address);
       
            %>
        </div>
    </form>
</body>
