How do I model the data in json format in c#? - json

Question

Given the following data in json format.
{
"timestamp": "2021-10-20T17:46:13",
"data":
[ // this is essentially a dictionary
{"Pressure": 0.11},
{"Temp A": 47.88},
{"Temp B": 46.69}
]
}
Is it correct to model in c#
public class PayloadModel
{
public DateTime Timestamp { get; set; }
public PayloadData Data { get; set; }
}
public class PayloadData
{
public Dictionary<string, float> Data { get; set; }
}
or
public class PayloadModel
{
public DateTime Timestamp { get; set; }
public List<Dictionary<string, float>> PayloadData { get; set; }
}
I'd like to deserialize into a c# class.
PayloadModel pm = JsonConvert.DeserializeObject<PayloadModel>(payload);
What's the correct way of modeling in c#?

Answer 1

you will have to fix a PayLoadModel class if you want to use your code
PayloadModel pm = JsonConvert.DeserializeObject<PayloadModel>(payload);
public class PayloadModel
{
[JsonProperty("timestamp")]
public DateTime Timestamp { get; set; }
[JsonProperty("data")]
public List<Dictionary<string, float>> PayloadData { get; set; }
}
But I recommend to use a Dictionary instead of a List of Dictionary
var jsonParsed =JObject.Parse(json);
PayloadModel pm = jsonParsed.ToObject<PayloadModel>();
pm.PayloadData= ((JArray) jsonParsed["data"])
.ToDictionary(p => ((JObject) p).Properties().First().Name,
p =>(float) ((JObject) p).Properties().First().Value);
public class PayloadModel
{
[JsonProperty("timestamp")]
public DateTime Timestamp { get; set; }
public Dictionary<string, float> PayloadData { get; set; }
}
