Xamarin Forms: How to parse a JSON response without a stable key?

I am using Newtonsoft.Json to parse my response. But for the below response I don't know how to create a model class and how to show it on an expander.

My Response:

{
"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"
            }
        ]
    }
}

I tried something like below:

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; }
}

Instead of 2021-05-03T05:00:00.000+0000 this what I can add to the model class? The response is a list of items inside another list. Plan to use an expander to show this on UI, so any extra implementation need for that?

Solution

I checked with the back end team and they changed the JSON response like below:

{
    "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"
                }
            ]
        }
    ]
}

Corressponding Model 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; }
}

Now I am able to parse the data and show it on an expander.

Thanks
