使用Json.net反序列化时处理额外的成员

Question

假设我想将一组Json数据反序列化为Person对象.

class Person
{
    [DataMember]
    string name;
    [DataMember]
    int age;
    [DataMember]
    int height;

    object unused;
}

但是,如果我有如下所示的Json数据:

{
    "name":"Chris",
    "age":100,
    "birthplace":"UK",
    "height":170,
    "birthdate":"08/08/1913",
}

"birthdate"和"birthplace"字段不属于Person类.但是我仍然希望保留这些字段,那么是否可以使用Json.net或其他可以将这些额外字段存储到Person字段之一的库,如上面声明的"未使用"？

您应该可以使用[JsonExtensionData]属性:http://james.newtonking.com/archive/2013/05/08/json-net-5-0-release-5-defaultsettings-and-extension- 数据

void Main()
{
    var str = "{\r\n    \"name\":\"Chris\",\r\n    \"age\":100,\r\n    \"birthplace\":\"UK\",\r\n    \"height\":170," +
    "\r\n    \"birthdate\":\"08/08/1913\",\r\n}";
    var person = JsonConvert.DeserializeObject<Person>(str);
    Console.WriteLine(person.name);
    Console.WriteLine(person.other["birthplace"]);
}

class Person
{
    public string name;
    public int age;
    public int height;
    [JsonExtensionData]
    public IDictionary<string, object> other;
}
