Question

我正在尝试扩展HelpScoutNet项目，以便我可以利用报告。我有一段时间从HelpScout获取JSON以反序列化到我的类中。希望你们能告诉我我做错了什么。

根据API文档的JSON：

 {
  "filterTags": [
    {
      "id": 123,
      "name": "sample-tag"
    },
    ...
  ],

    "resolutionTime": -47.245241919394445,

  }
}

JSON我从API回来了：

"{\"filterTags\":[{\"name\":\"general questions\",\"id\":295508},{\"name\":\"request/suggestion\",\"id\":372291},{\"name\":\"support.dd.com incorrect\",\"id\":547376},{\"name\":\"status update\",\"id\":295502},{\"name\":\"support.dd.com other\",\"id\":547378},{\"name\":\"promos/gift cards\",\"id\":295547}],\"user\":{\"createdAt\":\"2015-05-04T16:32:21Z\",\"photoUrl\":\"https://d33v4339jhl8k0.cloudfront.net/users/99999.23342.jpg\",\"hasPhoto\":true,\"name\":\"John Doe\",\"totalCustomersHelped\":261,\"id\":99999},\"current\":{\"startDate\":\"2015-08-15T12:00:00Z\",\"endDate\":\"2015-08-16T18:00:00Z\",\"totalDays\":1,\"resolved\":4,\"conversationsCreated\":0,\"closed\":11,\"totalReplies\":5,\"resolvedOnFirstReply\":3,\"percentResolvedOnFirstReply\":60.0,\"repliesToResolve\":1.25,\"handleTime\":346.6,\"happinessScore\":0.0,\"responseTime\":3467,\"resolutionTime\":4704.25,\"repliesPerDay\":5.0,\"customersHelped\":4,\"totalConversations\":12,\"conversationsPerDay\":12.0,\"busiestDay\":6}}"

我的课程：

public class User
{
    [DefaultValue(0)]
    public int ID { get; set; }
    public bool HasPhoto { get; set; }
    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    [JsonConverter(typeof(IsoDateTimeConverter))]
    public DateTime? CreatedAt { get; set; }
    public string Name { get; set; }
    public int TotalCustomersHelped { get; set; }
    public string PhotoURL { get; set; }
}

public class TimeRangeStats
{
    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    [JsonConverter(typeof(IsoDateTimeConverter))]
    public DateTime? StartDate { get; set; }
    [JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
    [JsonConverter(typeof(IsoDateTimeConverter))]
    public DateTime? EndDate { get; set; }
    public int TotalDays { get; set; }
    public int Resolved { get; set; }
    public int ConversationsCreated { get; set; }
    public int Closed { get; set; }
    public int TotalReplies { get; set; }
    public int ResolvedOnFirstReply { get; set; }
    public double PercentResolvedOnFirstReply { get; set; }
    public double RepliesToResolve { get; set; }
    public double HandleTime { get; set; }
    public double HappinessScore { get; set; }
    public double ResponseTime { get; set; }
    public double ResolutionTime { get; set; }
    public double RepliesPerDay { get; set; }
    public int CustomersHelped { get; set; }
    public int TotalConversations { get; set; }
    public double ConversationsPerDay { get; set; }
    public int BusiestDay { get; set; }
}

public class MultipleTimeRangeStats
{
    public double TotalConversations { get; set; }
    public double CustomersHelped { get; set; }
    public double HappinessScore { get; set; }
    public double RepliesPerDay { get; set; }
    public double ResolvedOnFirstReply { get; set; }
    public double HandleTime { get; set; }
    public double ConversationsPerDay { get; set; }
    public double Resolved { get; set; }
    public double RepliesToResolve { get; set; }
    public double ActiveConversations { get; set; }
    public double TotalReplies { get; set; }
    public double Closed { get; set; }
    public double ResponseTime { get; set; }
    public double ResolutionTime { get; set; }
    public double ConversationsCreated { get; set; }
}

public class Tag
{
    public string Name { get; set; }
    [DefaultValue(0)]
    public long ID { get; set; }
}

public class UserReport
{
    public List<Tag> FilterTags { get; set; }
    public User User { get; set; }
    public TimeRangeStats Current { get; set; }
    public TimeRangeStats Previous { get; set; }
    public MultipleTimeRangeStats Deltas { get; set; }
}

序列化程序设置：

private JsonSerializerSettings _serializerSettings
        {
            get
            {
                var serializer = new JsonSerializerSettings
                {
                    ContractResolver = new CamelCasePropertyNamesContractResolver(),
                    NullValueHandling = NullValueHandling.Ignore,
                    DefaultValueHandling = DefaultValueHandling.Ignore,
                    DateFormatHandling = DateFormatHandling.IsoDateFormat,                    
                };
                serializer.Converters.Add(new StringEnumConverter {CamelCaseText = true});

                return serializer;
            }
        }

我希望这不是一大堆要问的信息。

编辑：让跟踪器工作，得到这个结果。这是完全令人困惑的，它无法找到这些属性，但它适用于其他类，据我所知，它们是相同的：

Answer 1

您问题中的JSON与您的UserReport课程相对应，而不是SingleItem<UserReport> - 没有外部{"item": ...}容器对象。因此，您需要将其反序列化。

JSON.net反序列化返回一个null对象
