using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;using System.IO;using uzai.tools;using Newtonsoft.Json;namespace CodeTest.test8{    public partial class WebForm3 : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)        {            //json 反序列化1            string jsonString1 = "{\"Age\":28,\"Name\":\"张三\"}";            Person p1 = JsonHelper.JsonDeserialize<Person>(jsonString1);            //json 反序列化2            string jsonString = "[{treeId:13938,treeName:\"海洋水手号\"},{treeId:19955,treeName:\"内舱房\",imgId:19603,imgName:\"内舱房\"},{treeId:17929,treeName:\"济州蓝色海岸\"}]";            List<tree> p = Newtonsoft.Json.JsonConvert.DeserializeObject<List<tree>>(jsonString);        }               public class Person       {            public int Age { get; set; }            public string Name { get; set; }        }        public class tree        {            public int treeId { get; set; }            public string treeName { get; set; }            public int imgId { get; set; }            public string imgName { get; set; }        }    }}

方法1使用的 Jsonhelper

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization.Json;
using System.IO;

namespace uzai.tools
{
    /// <summary>

    /// JSON序列化和反序列化辅助类

    /// </summary>

    public class JsonHelper
    {

        /// <summary>

        /// JSON序列化

        /// </summary>

        public static string JsonSerializer<T>(T t)
        {

            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));

            MemoryStream ms = new MemoryStream();

            ser.WriteObject(ms, t);

            string jsonString = Encoding.UTF8.GetString(ms.ToArray());

            ms.Close();

            return jsonString;

        }

        /// <summary>

        /// JSON反序列化

        /// </summary>

        public static T JsonDeserialize<T>(string jsonString)
        {

            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));

            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));

            T obj = (T)ser.ReadObject(ms);

            return obj;

        }
    }
}

方法2 需要引用 Newtonsoft.Json.dll
