使用Newtonsoft序列化&反序列化

1.Json对象的序列化和反序列化

　　代码如下：

class Program
    {
        static void Main(string[] args)
        {
            //1.0 对象序列化成Json字符串
            ReturnModel model = new ReturnModel() { result = "true", errorcode = "0", message = "成功！" };
            string jsonStr = JsonConvert.SerializeObject(model);
            Console.WriteLine(jsonStr);



            //2.0 Json字符串反序列化为对象
            string jsonStr2 = "{"result":false,"errorcode":2,"message":"失败！",}";
            ReturnModel model2 = JsonConvert.DeserializeObject<ReturnModel>(jsonStr2);
            Console.WriteLine(model2.result + "||" + model2.errorcode + "||" + model2.message);

            Console.ReadKey();
        }
    }
    /// <summary>
    /// 返回消息模型
    /// dp 2017-02-10
    /// </summary>
    public class ReturnModel
    {
        /// <summary>
        /// 返回结果
        /// </summary>
        public string result { get; set; }

        /// <summary>
        /// 返回错误代码
        /// </summary>
        public string errorcode { get; set; }

        /// <summary>
        /// 返回消息
        /// </summary>
        public string message { get; set; }
    }
