对于本问题 我用三步来分别说明实现过程
1、定义一个类---- 实现转换的具体方法
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Serialization.Json;
namespace Test.JesonTest
{
public static class JsonHelper
{
//定义json操作运算
//将字jeson字符串转换为object对象
public static T strToObject<T>(string jsonString)
{
using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))
{
return (T)new DataContractJsonSerializer(typeof(T)).ReadObject(ms);
}
}
//将object对象反序列为jeson字符串
public static string objectToStr(object jsonObject)
{
using (var ms = new MemoryStream())
{
new DataContractJsonSerializer(jsonObject.GetType()).WriteObject(ms, jsonObject);
return Encoding.UTF8.GetString(ms.ToArray());
}
}
}
}
说明：首先，当然是项目是3.5+的；必须添加引用：System.Runtime.Serialization 和 System.ServiceModel
2、创建一个OBJECT对象类
using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace Test.JesonTest { public class Person { public int id { get; set; } public string name { get; set; } public int age { get; set; } public Person() { id = 0; name = "xuhyuan"; age = 88; } } }
3、具体调用实现实例
前台.aspx页面html。
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Testjeson.aspx.cs" Inherits="Test.JesonTest.Testjeson" %>

<br />
<asp:Button ID="but_str_obj" runat="server" Text="将jeson字符串转换为Object"

<asp:Button ID="but_obj_str" runat="server" Text="将Object换为jeson字符串转"

<br /><br />
<asp:textbox ID="txt_resoult" runat="server" Height="207px"
TextMode="MultiLine" Width="624px"></asp:textbox>
</div>
</form>
</body>
</html>
c#页面后台代码
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Script.Serialization; namespace Test.JesonTest { public partial class Testjeson : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } //将jeson字符串转换为object protected void but_str_obj_Click(object sender, EventArgs e) { string str_jeson = txt_resoult.Text.Trim(); if (!string.IsNullOrEmpty(str_jeson)) { List<Person> pes=new List<Person>(); pes = JsonHelper.strToObject<List<Person>>(str_jeson); str_jeson=""; for (int i = 0; i < pes.Count; i++) { str_jeson += "id=" + pes[i].id + ";name=" + pes[i].name + ";age=" + pes[i].age + "<br /><br /><br />"; } } txt_resoult.Text+=str_jeson; } //将object转换为jeson字符串 protected void but_obj_str_Click(object sender, EventArgs e) { Person pe = new Person(); List<Person> pes = new List<Person>(); pes.Add(pe); pes.Add(pe); pes.Add(pe); //反序列化实现 string json = JsonHelper.objectToStr(pes); txt_resoult.Text = json; // 序列化----利用js实现 //JavaScriptSerializer jss = new JavaScriptSerializer(); } } }
