修改jsonhelper类需用到的名称空间：
View Code
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;
using System.Collections.Generic;//List名称空间

jsonhelper类的修改：
View Code
public class JsonHelper
{

        /// <summary>
        /// json序列化
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="t"></param>
        /// <returns></returns>
        public static string JsonSerializer<T>(T t)
        {
            DataContractJsonSerializer zer = new DataContractJsonSerializer(typeof(T));
            MemoryStream ms = new MemoryStream();
            zer.WriteObject(ms, t);
            string jsonstring = Encoding.UTF8.GetString(ms.ToArray());
            ms.Close();

            string p = @"\\/Date\((\d+)\+\d+\)\\/";
            MatchEvaluator me = new MatchEvaluator(ConvertJsonDateToDateString);
            Regex rg = new Regex(p);
            jsonstring = rg.Replace(jsonstring, me);
            return jsonstring;
        }

        /// <summary>
        /// json反序列化
        /// </summary>
        /// <typeparam name="T" _cke_saved_name="T"></typeparam>
        /// <param name="jsonstring"></param>
        /// <returns></returns>
        public static T JsonDeserializer<T>(string jsonstring)
        {
            string p = @"\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2}";
            MatchEvaluator me = new MatchEvaluator(ConvertDateTimeToJsonDate);
