可以解决如下json格式的字符串不能使用DataContractJsonSerializer反序列化

{

    "ss": "sss",

    "ss1": "sss",

    "ss2": "sss",

    "ss3": "sss"

}

这样的json反序列化为Dictionary<string, string>对象

需要导入System.Web.Extensions.dll下的System.Web.Script.Serialization命名空间

using System;

using System.Web.Script.Serialization;

namespace Imooly.Service.Umeng.MessagePush

{

    /// <summary>

    /// Json操作帮助类

    public static class JsonHelper

    {

        /// <summary>

        /// 对象转换成json

        /// </summary>

        /// <param name="jsonObject">需要格式化的对象</param>

        /// <returns>Json字符串</returns>

        /// <remarks>create by chenjinjian.com on 2015-01-26</remarks>

        public static string Serialize(object jsonObject)

        {

            string jsonString = string.Empty;

            if (jsonObject != null)

            {

                var serializer = new JavaScriptSerializer();

                jsonString = serializer.Serialize(jsonObject);

            }

            return jsonString;

        }

        /// <summary>

        /// json字符串转换成对象

        /// </summary>

        /// <typeparam name="T"></typeparam>

        /// <param name="jsonString">要转换成对象的json字符串</param>

        /// <returns>返回T对象</returns>

        /// <remarks>create by chenjinjian.com on 2015-01-26</remarks>

        public static T Deserialize<T>(string jsonString)

        {

            T obj = default(T);

            if (!string.IsNullOrEmpty(jsonString))

            {

                var serializer = new JavaScriptSerializer();

                obj = serializer.Deserialize<T>(jsonString);

            }

            return obj;

        }

    }

}
