Question

假设我有一个班级

public class Person
{
    public int id { get; set; }
    public string name { get; set; }
    public DateTime dateOfBirth { get; set; }
}

和第二课

public class Classroom
{
    public Person teacher { get; set; }
    public List<Person> students { get; set; }
}

我想要实现的目标是：

当我JSON序列化一个Person实例时，我希望序列化该人的所有属性。但是当我序列化一个Classroom实例时，我只希望序列化Person的id和name属性

示例：

var teacher = new Person { id = 0, name = "Anna", dateOfBirth = new Datetime(1989, 10, 1) }
var student1 = new Person { id = 1, name = "Nick", dateOfBirth = new Datetime(2009, 4, 14) }
var student2 = new Person { id = 2, name = "Helen", dateOfBirth = new Datetime(2009, 6, 23) }
var classRoom = new Classroom
{
    teacher = teacher,
    students = new List<Student> { student1, student2 }
}

var techerJson = JsonConvert.Serialize(teacher, ...)
var studentJson = JsonConvert.Serialize(student1, ...)
var classRoomJson = JsonConvert.Serialize(classRoom, ...)


// techerJson == { id: 0, name: 'Anna', dateOfBirth: '1989-10-01T00:00:00' }
// studentJson == { id: 1, name: 'Nick', dateOfBirth: '2009-04-14T00:00:00' }
// classRoomJson == 
// {
//      teacher: { id: 0, name: 'Anna' },
//      students: [
//          { id: 1, name: 'Nick' },
//          { id: 2, name: 'Helen' }
//      ]
// }

我可以使用自定义合约解析程序或任何其他方式实现这一目标吗？

根据使用JSON.NET的实体的嵌套级别来条件地序列化属性
