使用JSON.NET将平面JSON对象反序列化为复杂对象(Deserialising a flat JSON object into a complex object using JSON.NET)

 我正在从一个我无法控制的外部API中检索一些JSON，并且需要将其反序列化为一个对象，其中一些字段嵌套到主对象的属性中，因此直接反序列化将不起作用。 
 
 我发现的最接近的问题是： 
 
 Json .Net将平面对象序列化为复杂对象（在序列化/反序列化时更改对象结构） 
 
 我不能真正将它应用于我的问题，因为我对使用JSON.NET相当新，并且仍然试图理解它是如何工作的。 
 
 一个小样本，用于演示API中的json： 
 
{
  FirstName: "John",
  LastName: "Smith",
  PassportNo: "xxxxx",
  NiNo: "xxxxx",
}
 
 我想要反序列化的类： 
 
internal sealed class Person
{
    [JsonProperty(PropertyName = "FirstName")]
    public string FirstName { get; set; }

    [JsonProperty(PropertyName = "LastName")]
    public string LastName { get; set; }

    public PrivateData PrivateData { get; set; }
}

internal sealed class PrivateData
{
    [JsonProperty(PropertyName = "PassportNo")]
    public string PassportNo { get; set; }

    [JsonProperty(PropertyName = "NiNo")]
    public string NationalInsuranceNumber { get; set; }
}
 
 我不知道如何实现自定义合同解析器/ JSON转换器以获得所需的结果，因此任何指导都将受到赞赏。 

I am retrieving some JSON from an external API that I have no control over and need to deserialise that into an object where some of the fields are nested into a property of the main object so a straight deserialise won't work.
 
The closest question I've found to my issue is:
 
Json .Net serialize flat object into a complex object (change objects structure on serialization/deserialization)
 
I couldn't really apply this to my problem though as i'm fairly new to using JSON.NET and still trying to understand how it works.
 
A small sample to demonstrate of the json back from the API:
 
{
  FirstName: "John",
  LastName: "Smith",
  PassportNo: "xxxxx",
  NiNo: "xxxxx",
}
 
The class(es) I want to deserialise into:
 
internal sealed class Person
{
    [JsonProperty(PropertyName = "FirstName")]
    public string FirstName { get; set; }

    [JsonProperty(PropertyName = "LastName")]
    public string LastName { get; set; }

    public PrivateData PrivateData { get; set; }
}

internal sealed class PrivateData
{
    [JsonProperty(PropertyName = "PassportNo")]
    public string PassportNo { get; set; }

    [JsonProperty(PropertyName = "NiNo")]
    public string NationalInsuranceNumber { get; set; }
}
 
I wasn't sure how to go about implementing a custom contract resolver / JSON converter to attain the required results so any guidance would be appreciated.
