How do I deserialize this JSON-object ?

Question

0.00/5 (No votes)

See more:

I have a JSON-String which looks like this :

{"wifi_sta":{"connected":true
"mqtt":{"connected":false}
"actions_stats":{"skipped":0}
"relays":[{"ison":false
"has_timer":false
"is_valid":true
{"ison":false
"has_timer":false
"is_valid":true}]
}

basicly I know how to deserialize JSON-Strings and assign them to a class - but now and here I have a class in a class ... AND ... the identifiers a equal.
The main-identifier is "relays" and the both sub-identifiers are the both "ison".
So ... there is my problem and I don't know how the class-object should look like ...

I'm very interested in Suggestions ...

What I have tried:

I created a sub-class with an array in it (ison(1) of boolean) - but that isn't assigned.
I created a structure with an array in it (ison() of boolean) - but that isn't assigned.

I also found this Article - but I don't understood it :

Well, for a start, that "JSON" is invalid. At a guess, it should look more like this:

JSON

{
    "wifi_sta": {
        "connected":true,
        "mqtt":{"connected":false},
        "actions_stats":{"skipped":0},
        "relays":[
            {
                "ison":false,
                "has_timer":false,
                "is_valid":true
            },
            {
                "ison":false,
                "has_timer":false,
                "is_valid":true
            }
        ]
    }
}

Once you have valid JSON, you can use Visual Studio's "paste JSON as classes" option to generate the classes you need to deserialize into.

Or you can use an online tool like quicktype[^] to generate the classes for you - although that one doesn't support VB.NET, but translating from C# shouldn't be too hard.

C#

public class Root
{
    [JsonPropertyName("wifi_sta")]
    public WifiSta WifiSta { get; set; }
}

public partial class WifiSta
{
    [JsonPropertyName("connected")]
    public bool Connected { get; set; }

    [JsonPropertyName("mqtt")]
    public Mqtt Mqtt { get; set; }

    [JsonPropertyName("actions_stats")]
    public ActionsStats ActionsStats { get; set; }

    [JsonPropertyName("relays")]
    public Relay[] Relays { get; set; }
}

public partial class ActionsStats
{
    [JsonPropertyName("skipped")]
    public long Skipped { get; set; }
}

public partial class Mqtt
{
    [JsonPropertyName("connected")]
    public bool Connected { get; set; }
}

public partial class Relay
{
    [JsonPropertyName("ison")]
    public bool Ison { get; set; }

    [JsonPropertyName("has_timer")]
    public bool HasTimer { get; set; }

    [JsonPropertyName("is_valid")]
    public bool IsValid { get; set; }
}
