这是一个.NET实用工具类，用于将对象转换为JSON字符串以及从JSON字符串反序列化回对象。使用了System.Runtime.Serialization.Json命名空间中的DataContractJsonSerializer类。

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

namespace WebApiDemo2.Utils
{
    public class CJsonUtil
    {
        public static string ObjectToJson(object obj)
        {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            MemoryStream stream = new MemoryStream();
            serializer.WriteObject(stream, obj);
            byte[] dataBytes = new byte[stream.Length];
            stream.Position = 0;
            stream.Read(dataBytes, 0, (int)stream.Length);
            return Encoding.UTF8.GetString(dataBytes);
        }

        // 从一个Json串生成对象信息
        public static object JsonToObject(string jsonString, object obj)
        {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            MemoryStream mStream = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
            return serializer.ReadObject(mStream);
        }
    }
}
