問題描述

我正在嘗試將 API 用于知名的在線會議提供商.他們的其中一個(gè) API 調(diào)用返回一個(gè)如下所示的對象.

I am trying to make use of the API for a well known online meeting provider. One of their API calls returns an object that looks like this.

{
    "5234592":{
    "pollsAndSurveys":{
        "questionsAsked":1,
        "surveyCount":0,
        "percentageSurveysCompleted":0,
        "percentagePollsCompleted":100,
        "pollCount":2},
    "attendance":{
        "averageAttendanceTimeSeconds":253,
        "averageInterestRating":0,
        "averageAttentiveness":0,
        "registrantCount":1,
        "percentageAttendance":100}
    },
    "5235291":{
    "pollsAndSurveys":{
        "questionsAsked":2,
        "surveyCount":0,
        "percentageSurveysCompleted":0,
        "percentagePollsCompleted":0,
        "pollCount":0},
    "attendance":{
        "averageAttendanceTimeSeconds":83,
        "averageInterestRating":0,
        "averageAttentiveness":0,
        "registrantCount":1,
        "percentageAttendance":100}
    }
}

我正在嘗試在 C# 中創(chuàng)建一個(gè)強(qiáng)類型對象，以便處理這些數(shù)據(jù).我可以為 pollsAndSurveys 位和出勤位創(chuàng)建對象，但我不知道如何處理 id 號，在本例中為 5234592 &5235291，即會話的標(biāo)識符.

I am trying to make a strongly typed object in C# so I can deal with this data. I can create objects for the pollsAndSurveys bit and the attendance bit but I don't know how to deal with the id number, in this case 5234592 & 5235291, that is the identifier for the session.

public class AttendanceStatistics
{
    [JsonProperty(PropertyName = "registrantCount")]
    public int RegistrantCount { get; set; }

    [JsonProperty(PropertyName = "percentageAttendance")]
    public float PercentageAttendance{ get; set; }

    [JsonProperty(PropertyName = "averageInterestRating")]
    public float AverageInterestRating { get; set; }

    [JsonProperty(PropertyName = "averageAttentiveness")]
    public float AverageAttentiveness { get; set; }

    [JsonProperty(PropertyName = "averageAttendanceTimeSeconds")]
    public float AverageAttendanceTimeSeconds { get; set; }
}

public class PollsAndSurveysStatistics
{
    [JsonProperty(PropertyName = "pollCount")]
    public int PollCount { get; set; }

    [JsonProperty(PropertyName = "surveyCount")]
    public float SurveyCount { get; set; }

    [JsonProperty(PropertyName = "questionsAsked")]
    public int QuestionsAsked { get; set; }

    [JsonProperty(PropertyName = "percentagePollsCompleted")]
    public float PercentagePollsCompleted { get; set; }

    [JsonProperty(PropertyName = "percentageSurveysCompleted")]
    public float PercentageSurveysCompleted { get; set; }
}

public class SessionPerformanceStats
{
    [JsonProperty(PropertyName = "attendance")]
    public AttendanceStatistics Attendance { get; set; }

    [JsonProperty(PropertyName = "pollsAndSurveys")]
    public PollsAndSurveysStatistics PollsAndSurveys { get; set; }
}

public class WebinarPerformanceStats
{
    public List<SessionPerformanceStats> Stats { get; set; }
}

我很確定 WebinarPerformanceStats 是問題所在，但我不知道從哪里開始.我必須改變什么才能得到

I am pretty sure that the WebinarPerformanceStats is the issue but I don't know where to go from here. What would I have to change to get

NewtonSoft.Json.JsonConvert.DeserializeObject<WebinarPerformanceStats>(theJsonResponse)

上班?

推薦答案

讓你的根對象成為字典:

Make your root object be a dictionary:

var dictionary = JsonConvert.DeserializeObject<Dictionary<string, SessionPerformanceStats>>(theJsonResponse);

Json.NET 將字典從 JSON 對象序列化到 JSON 對象，并將鍵轉(zhuǎn)換為屬性名稱.在您的情況下，ID 號將被反序列化為字典鍵.如果您確定它們將始終是數(shù)字，則可以這樣聲明它們:

Json.NET serializes a dictionary from and to a JSON object, with the keys being converted to the property names. In your case, the ID numbers will be deserialized as the dictionary keys. If you are sure they will always be numbers, you could declare them as such:

var dictionary = JsonConvert.DeserializeObject<Dictionary<long, SessionPerformanceStats>>(theJsonResponse);
