如何使用Newtonsoft处理不同的JSON

Question

我正在使用API​​响应，并且该响应包含项目列表。这是示例JSON

{
    "attendeeid": "1",
    "responses": {
    "1": {
        "questionid": "1",
        "fieldname": "1",
        "name": "question?",
        "pageid": "2",
        "page": "Attendee Information",
        "auto_capitalize": "0",
        "choicekey": "",
        "response": [
            " Identify need",
            " Evaluate products and services"
        ]
    },
    "2": {
        "questionid": "2",
        "fieldname": "2",
        "name": "question2",
        "pageid": "2",
        "page": "Attendee Information",
        "auto_capitalize": "0",
        "choicekey": "live",
        "response": "live"
    },
},
}

如您所见，响应中的响应字段可以是对象或字符串。

如何创建可以反序列化的POCO对象？目前我的课程是

    public class RegistrantInfoResponse
    {
        public string questionid { get; set; }
        public string fieldname { get; set; }
        public string name { get; set; }
        public string response { get; set; }
    }

    public class RegistrantInfo
    {
        public string attendeeid { get; set; }
        public List<RegistrantInfoResponse> responses { get; set; }
    }

像这样更改您的Json：

{
    "attendeeid": "1",
    "responses": {
        "QuestionOne": {
            "questionid": "1",
            "fieldname": "1",
            "name": "question?",
            "pageid": "2",
            "page": "Attendee Information",
            "auto_capitalize": "0",
            "choicekey": "",
            "response": [
                " Identify need",
                " Evaluate products and services"
            ]
        },
        "QuestionTwo": {
            "questionid": "2",
            "fieldname": "2",
            "name": "question2",
            "pageid": "2",
            "page": "Attendee Information",
            "auto_capitalize": "0",
            "choicekey": "live",
            "response": "live"
        }
    }
}

在json2csharp上产生以下类集：

public class QuestionOne
{
    public string questionid { get; set; }
    public string fieldname { get; set; }
    public string name { get; set; }
    public string pageid { get; set; }
    public string page { get; set; }
    public string auto_capitalize { get; set; }
    public string choicekey { get; set; }
    public List<string> response { get; set; }
}

public class QuestionTwo
{
    public string questionid { get; set; }
    public string fieldname { get; set; }
    public string name { get; set; }
    public string pageid { get; set; }
    public string page { get; set; }
    public string auto_capitalize { get; set; }
    public string choicekey { get; set; }
    public string response { get; set; }
}

public class Responses
{
    public QuestionOne QuestionOne { get; set; }
    public QuestionTwo QuestionTwo { get; set; }
}

public class RootObject
{
    public string attendeeid { get; set; }
    public Responses responses { get; set; }
}

哪个应该让您先于序列化/反序列化。
