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

    {

        public string BookID { get; set; }

        public DateTime PublishDate { get; set; }

        public decimal Price { get; set; }



        public 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());
