这两天写这个xml跟json的读写，心累啊，也不是很理解，请大家多指教
首先来个热身菜做一个简单的解析json
在script里写一个简单的弹窗效果
<script>
//script里简单的解析json
var json = ‘{"name": "学生","info": [{ "count": "1", "stuname": "张三 ", "stuNO": "123" }, { "count": "2", "stuname": "里斯 ", "stuNO": "456" }] }‘
var obj = JSON.parse(json);
alert(obj.name);
alert(obj.info[0].count);//按顺序弹出消息弹框
alert(obj.info[1].stuname);
</script>
效果如图
注意：在进行asp.net与json转换时，要首先安装一个json转化工具
项目—管理NuGet程序包—打开之后如图所示操作
工具包装好后要记得引用using Newtonsoft.Json;
案例
新建两个学生类Student.cs,StuList.cs和一个web窗体WebForm.aspx
1.Student.cs代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace asp.net解析json
{
public class Student
{
public string StuNO { get; set; }
public string StuName { get; set; }
public Student()
{
}
public Student(string StuNO, string StuName)
{
this.StuNO = StuNO;
this.StuName = StuName;
}
}
}
2.StuList.cs代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace asp.net解析json
{
public class StuList
{
public int count;
public List<Student> data;
public StuList()
{
}
}
}
3.WebForm.aspx代码
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="asp.net解析json.WebForm1" %>
<!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">
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
<div>
<asp:Label ID="Label2" runat="server" Text=""></asp:Label>
</div>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="对象转json" />
<asp:Button ID="Button2" runat="server" Text="json转对象" OnClick="Button2_Click" />
</form>
</body>
</html>
4.WebForm.aspx.cs代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Newtonsoft.Json;//要记得引用
namespace asp.net解析json
{
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
Student zhangsan = new Student("1001","张三");
Student lisi = new Student("1002","李四");
List<Student> stulist = new List<Student>();//存储在集合里
stulist.Add(zhangsan);
stulist.Add(lisi);
StuList stuList = new StuList();
stuList.count = stulist.Count;
stuList.data = stulist;
string json = JsonConvert.SerializeObject(stuList);
ViewState["json"] = json;//获取你保存在网页里的信息
Label1.Text = json;
}
protected void Button2_Click(object sender, EventArgs e)
{
string json = ViewState["json"].ToString();
StuList stu = JsonConvert.DeserializeObject<StuList>(json);
for (int i = 0; i < stu.count; i++)//遍历集合里的数据
{
string info = "学号：" + stu.data[i].StuNO + "姓名：" + stu.data[i].StuName + "<hr />";
Label2.Text += info;
}
}
}
}
测试结果
game over
