我正在尝试用C#创建一个自定义类型，它可以rdap.org在JSON反序列化时处理www.example.com响应（出于我的目的，我将使用netwonsoft）。
例如，在向以下对象发出GET请求时：https://rdap.org/domain/stackoverflow.com返回以下JSON字符串：

{
    "objectClassName": "domain",
    "handle": "108907621_DOMAIN_COM-VRSN",
    "ldhName": "STACKOVERFLOW.COM",
    "links": [
        {
            "value": "https://rdap.verisign.com/com/v1/domain/STACKOVERFLOW.COM",
            "rel": "self",
            "href": "https://rdap.verisign.com/com/v1/domain/STACKOVERFLOW.COM",
            "type": "application/rdap+json"
        },
        {
            "value": "https://apis.cscglobal.com/dbs/rdap-api/v1/domain/STACKOVERFLOW.COM",

        }
    ],

                }
            ]
        }
    ]
}

根据json2csharp.com，以下自定义类型将执行此操作：

// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
    public class Entity
    {
        public string objectClassName { get; set; }
        public List<string> roles { get; set; }
        public List<Remark> remarks { get; set; }
        public List<string> status { get; set; }
        public string handle { get; set; }
        public List<object> vcardArray { get; set; }
        public List<Entity> entities { get; set; }
        public List<PublicId> publicIds { get; set; }
        public List<Event> events { get; set; }
        public List<Link> links { get; set; }
    }

    public class Event
    {
        public string eventAction { get; set; }
        public DateTime eventDate { get; set; }
        public string eventActor { get; set; }
    }

    public class Link
    {
        public string rel { get; set; }
        public string value { get; set; }
        public string href { get; set; }
        public string type { get; set; }
        public string title { get; set; }
    }

    public class Nameserver
    {
        public string objectClassName { get; set; }
        public string handle { get; set; }
        public string ldhName { get; set; }
        public List<string> status { get; set; }
        public List<Event> events { get; set; }
        public List<Link> links { get; set; }
    }

    public class Notice
    {
        public string title { get; set; }
        public List<string> description { get; set; }
        public List<Link> links { get; set; }
    }

    public class PublicId
    {
        public string identifier { get; set; }
        public string type { get; set; }
    }

    public class Remark
    {
        public string title { get; set; }
        public string type { get; set; }
        public List<string> description { get; set; }
        public List<Link> links { get; set; }
    }

    public class Root
    {
        public List<string> rdapConformance { get; set; }
        public string objectClassName { get; set; }
        public string handle { get; set; }
        public string ldhName { get; set; }
        public List<string> status { get; set; }
        public List<Event> events { get; set; }
        public SecureDNS secureDNS { get; set; }
        public List<Entity> entities { get; set; }
        public List<Nameserver> nameservers { get; set; }
        public List<Notice> notices { get; set; }
        public List<Link> links { get; set; }
    }

    public class SecureDNS
    {
        public bool delegationSigned { get; set; }
    }

事实上，它确实正确地将json反序列化为类型，只是有一个非常小而微妙的问题：源代码public List<object> vcardArray { get; set; }中的一行使用了一个“object”列表，使得访问vcardArray非常困难。我目前正在将每个对象转换为字符串，并使用正则表达式访问它们，但这似乎不正确，感觉很挑剔。
有没有什么方法可以修改Entity类而不使用vcardArray的“object”？也许可以使用其他类？到目前为止，我所做的每一次尝试都在反序列化时失败。

可以创建VCard类并将JsonConstructor添加到Entity类

public class VCard
{
    public string CardType { get; set; }
    public string ContactType { get; set; }
    public string ValType { get; set; }
    public string Val { get; set; }
}
public class Entity
{
    //another properties

    public List<VCard> VCards { get; set; }

    [JsonConstructor]
    public Entity(JToken vcardArray)
    {
        VCards = vcardArray.OfType<JArray>()
                                 .Select(i => i.Select(x => new VCard
                                 {
                                     CardType = x[0].ToString(),
                                     ContactType = ((JObject)x[1]).Properties().Count() == 0 ? ""
                                                    : String.Join(",", ((JObject)x[1]).Properties()),
                                     ValType = x[2].ToString(),
                                     Val = x[3].ToString()
                                 })
                                  .ToList())
                                  .First();
    }
}
