Newtonsoft.Json（Json.net）的基本用法

添加引用：

使用NuGet，命令：install-package Newtonsoft.Json

实体类：

    public class Book
    {
        string BookID { get; set; }
        public DateTime PublishDate { decimal Price { ; }

        override string ToString()
        {
            return "ID:" + BookID + ; Date:" + PublishDate.ToShortDateString() + ; Price" + Price.ToString(n");
        }
    }

序列化和反序列化：

            Book bk = new Book() { BookID = 12111",PublishDate = DateTime.Parse(2012-2-1 22:12:11"),Price=433.12M};
            Console.WriteLine(JsonConvert.SerializeObject(bk));

            string jsonBook = {'BookID':'123','PublishDate':'2011-1-2','Price':23.5};
            Book bk1 = JsonConvert.DeserializeObject<Book>(jsonBook);
            Console.WriteLine(bk1.ToString());
