How to parse json with an array into object

Question

Consider the following json:

{
  "0": {
    "id": "1",
    "email": "someemail@test.com",
    "tstamp": "2019-01-21 11:19:48",
    "times": "2",
    "tstamp_iso": "2019-01-21T12:19:48-05:00"
  },
  "1": {
    "id": "2",
    "email": "someotheremail@test.com",
    "tstamp": "2019-01-21 11:25:48",
    "times": "2",
    "tstamp_iso": "2019-01-21T12:25:48-05:00"
  },
  "result_code": 1,
  "result_message": "Success!",
  "result_output": "json"
}

I am trying to convert that data into ac# object, however, I'm not sure how to go about the array value as it has 0 , 1 for its name instead of it being nested in an array and it will go on up until 20 if there are 20 results. I can't change the json data.

I got this far:

[JsonObject]
public class FirstObject
{
    [JsonProperty(PropertyName = "id")]
    public string Id { get; set; }

    [JsonProperty(PropertyName = "email")]
    public string Email { get; set; }

    [JsonProperty(PropertyName = "tstamp")]
    public string TimeStamp { get; set; }

    [JsonProperty(PropertyName = "times")]
    public string Times { get; set; }

    [JsonProperty(PropertyName = "tstamp_iso")]
    public string TimeStampIso { get; set; }
}

[JsonObject]
public class SecondObject
{
    public FirstObject[] FirstObjects { get; set; }

    [JsonProperty(PropertyName = "result_code")]
    public string ResultCode { get; set; }

    [JsonProperty(PropertyName = "result_message")]
    public string ResultMessage { get; set; }

    [JsonProperty(PropertyName = "result_output")]
    public string ResultOutput { get; set; }
}

What I don't understand is how to map FirstObjects to results of 0, 1, ... 20. I am hoping there is a better way than writing out that 20 times and setting the name to 0, or 1, etc...
