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。

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

<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();
}
}
