C# JsonHelper

建议直接用json.net:  http://www.cnblogs.com/xwgli/archive/2013/08/30/3290964.html

添加引用：System.Runtime.Serialization

JsonHelper.cs代码如下：

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

namespace Common
{
    /// <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;
        }
    }
}
