Json.NET在没有父级的情况下序列化对象属性

Question

Using Json.NET is it possible to serialize an object's fields instead of the object itself?

In JMS Serializer (PHP) I can use the @Inline annotation.

public class ApiResponseData
{
    public User User { get; set; }
}

public class User
{
    public string Username { get; set; }
    public string Firstname { get; set; }
    public string Lastname { get; set; }
}

If I serialize ApiResponseData I would like to get just username, firstname and lastname, not the User property.

Actual: { "user": { "username": "username", "firstname": "firstname", "lastname": "lastname" } }
Desired: { "username": "username", "firstname": "firstname", "lastname": "lastname" }

Answer 1

You can try to serialize ApiResponseData.User instead of serializing ApiResponseData itself. This way it will only serialize the values of ApiResponseData.User . Like:

 Newtonsoft.Json.JsonConvert.SerializeObject(ApiResponseData.User);

Answer 2

In the classes that contain objects of this class, you can add internal properties that return the value of the member you wish to serialize. Not the most elegant solution, but it works.
