1.将类转换成Json

定义实体类

    public class Person
    {
        public string Name { set; get; }
        public int Age { set; get; }
    }

//转成json
string json = JsonConvert.SerializeObject(new Person() { Name = "风铃",Age = 18 });
Console.WriteLine(json);
//json转实体
Person p = (Person) JsonConvert.DeserializeObject(json,typeof(Person));
Console.WriteLine(p.Name);
