Xamarin Forms：如何在没有稳定密钥的情况下解析 JSON 响应？

Question

我正在使用 Newtonsoft.Json 来解析我的回复。但是对于以下响应，我不知道如何创建模型 class 以及如何在扩展器上显示它。

我的回复：

{
"calendarEvents": {
        "2021-05-03T05:00:00.000+0000": [
            {
                "title": "Event 2",
                "description": "Event 2"
            }
        ],
        "2021-05-04T05:00:00.000+0000": [
            {
                "title": "Event 3",
                "description": "Event 3"
            }
        ],
        "2021-05-05T05:00:00.000+0000": [
            {
                "title": "Event 3",
                "description": "Event 3"
            },
            {
                "title": "Event 4",
                "description": "Event 4"
            }
        ]
    }
}

我试过类似下面的方法：

public class MyEvents
{
    public List<calendarEvents> calendarEvents { get; set; }
}

public class calendarEvents
{
    //What will be here? it is also a list and it has no stable key
}

public class Dummy//(Top class name here)
{
    public string title { get; set; }
    public string description { get; set; }
}

而不是 2021-05-03T05:00:00.000+0000 我可以将什么添加到模型 class？响应是另一个列表中的项目列表。计划使用扩展器在 UI 上显示此内容，因此需要任何额外的实施吗？

Answer 1

public class calendarEvents
{
    public Dictionary<string, List<Dummy>> item {get; set;}
}

public class Dummy//(Top class name here)
{
    public string title { get; set; }
    public string description { get; set; }
}

这就是您的日历事件的外观。您可以将字符串更改为 DateTime。

此示例的模型 JSON 很糟糕，它应该如下所示：

public class MyEvents
{
    [JsonProperty("calendarEvents")]
    public Dictionary<string, List<CalendarEvent>> calendarEvents{ get; set; }
}

public class CalendarEvent
{
    [JsonProperty("title")]
    public string Title { get; set; }

    [JsonProperty("description")]
    public string Description { get; set; }
}

Answer 2

我咨询了后端团队，他们更改了 JSON 响应，如下所示：

{
    "calendarEvents": [
        {
            "day": "20210503",
            "list": [
                {
                    "title": "Event 3",
                    "description": "Event 3"
                }
            ]
        },
        {
            "day": "20210504",
            "list": [
                {
                    "title": "Event 3",
                    "description": "Event 3"
                },
                {
                    "title": "Event 4",
                    "description": "Event 4"
                }
            ]
        },
        {
            "day": "20210505",
            "list": [
                {
                    "title": "Event 3",
                    "description": "Event 3"
                },
                {
                    "title": "Event 4",
                    "description": "Event 4"
                },
                {
                    "title": "Event 5",
                    "description": "Event 5"
                }
            ]
        }
    ]
}

对应型号Class：

public class List
{
    public string title { get; set; }
    public string description { get; set; }
}

public class CalendarEvent
{
    public string day { get; set; }
    public List<List> list { get; set; }
}

public class Root
{
    public List<CalendarEvent> calendarEvents { get; set; }
}

现在我可以解析数据并将其显示在扩展器上了。

谢谢
