[.Net码农].Net中的json操作类

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:
