[.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 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() {                   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(json); 结果:
