洪大师二次封装：

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

namespace DevFramework_2015.Common
{
    public class JsonHelper
    {
        public static string ListToJson<T>(List<T> li)
        #region
        {
            string jsonString = "";
            jsonString = JsonConvert.SerializeObject(li, Formatting.None);
            return jsonString;
        }
        #endregion



        public static List<T> JsonToList<T>(string jsonString)
        #region
        {
            List<T> li = JsonConvert.DeserializeObject<List<T>>(jsonString);

            return li;
        }
        #endregion



        public static string DictionaryToJson<TKey, TValue>(Dictionary<TKey, TValue> dic)
        #region
        {
            string jsonString = "";
            jsonString = JsonConvert.SerializeObject(dic, Formatting.None);
            return jsonString;
        }
        #endregion



        public static Dictionary<TKey, TValue> JsonToDictionary<TKey, TValue>(string jsonString)
        #region
        {
            Dictionary<TKey, TValue> dic = JsonConvert.DeserializeObject<Dictionary<TKey, TValue>>(jsonString);

            return dic;
        }
        #endregion



        public static string ArrayToJson<T>(T[] arrayObject)
        #region
        {
            string jsonString = "";
            jsonString = JsonConvert.SerializeObject(arrayObject, Formatting.None);

            return jsonString;
        }
        #endregion



        public static T[] JsonToArray<T>(string jsonString)
        #region
        {
            T[] arrayObject = JsonConvert.DeserializeObject<T[]>(jsonString);

            return arrayObject;
        }
        #endregion



        public static string DataTableToJson(DataTable dt)
        #region
        {
            string jsonString = "";

            jsonString = JsonConvert.SerializeObject(dt, Formatting.None);

            return jsonString;
        }
        #endregion



        public static DataTable JsonToDataTable(string jsonString)
        #region
        {
            DataTable dt;

            dt = JsonConvert.DeserializeObject<DataTable>(jsonString);

            return dt;         

        }
        #endregion
    }
}

 

对象直接转化为json字符串：

string jsonstr = JsonConvert.SerializeObject(response)

 json字符串转化为已知的对象

Response_QueryPrepareInfo _Response_QueryPrepareInfo = JsonConvert.DeserializeObject<Response_QueryPrepareInfo>(sRetStr);
