[.Net码农].Net中的json操作类

http://blog.163.com/hy_85/blog/static/1484587662011465235773/

以前要转json一般都是自己手工去写,再不济就是用Newtonsoft.Json.dll这个第三方的类库

今天突然发现.NET4.0里面自带了,这可真是一个伟大的发现

准备工作

 

需要引用

System.Web.Extensions.dll 这个类库

命名空间:

System.Web.Script.Serialization

 

 数据结构

    public class Team
    {
        public string Name { get; set; }
        public List<User> Users { get; set; }
    } 
    public class User
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

 

     Class --> JSON

JavaScriptSerializer js = new JavaScriptSerializer();
            Team team = new Team()
            {
                Name = "梦之队",
                Users = new List<User>() { 
                 new User() { Id = 1, Name = "XXX" },
                  new User() { Id = 2, Name = "YYY" },
                   new User() { Id = 3, Name = "ZZZ" },
                }
            };
            string json = js.Serialize(team);
            Console.WriteLine(json);

输出结果

 

Json --> Class

            string json = "{\"Name\":\"梦之队\",\"Users\":[{\"Id\":1,\"Name\":\"XXX\"},{\"Id\":2,\"Name\":\"YYY\"},{\"Id\":3,\"Name\":\"ZZZ\"}]}";
            JavaScriptSerializer js = new JavaScriptSerializer();
            Team team = js.Deserialize<Team>(json);

结果:
