I need to Serealize/Desseralize Save/Get in this json type in on Windows Forms C# project:
This project is used to save informations from CAN-Variables

[{
“Nome”: “Esp 03”,
“Local”: “Praça,
“IP”: “192.168.1.212”,
“Variables”:[{
“Nome”:”RPM”,
“id”:”0X12″,
“Startbit”: 1,
“Lenght”: 3,
“Factor”: 0.1,
“Offset”:1
},
{
“Nome”:”Pedal”,
“id”:”0X12″,
“Startbit”: 5,
“Lenght”: 1,
“Factor”: 1,
“Offset”:0
}]
}]

How i can make this?

I trying ins this form:

namespace PuxadinhoSGE
{
    class Variables
    {
        public string Nome { get; set; }
        public int Id { get; set; }

        public int Startbit { get; set; }
        public int Lenght { get; set; }

        public float Factor { get; set; }

        public float Offset { get; set; }

    }
    
    class Dispostivo
    {
        public string Nome { get; set; }
        public string Local { get; set; }
        public string IP { get; set; }
        public ListView Variables { get; set; }

        public string JsonSerializar(Dispostivo device)
        {
            Dispostivo Temp = new Dispostivo();
            Temp.Nome = device.Nome;
            Temp.Local = device.Local;
            Temp.IP = device.IP;

            String defaultValues = JsonConvert.SerializeObject(Temp);
            String defaultVariables = this.JsonSeriaLista(device.Variables)

            String ResultJson = defaultValues+defaultVariables;

            return ResultJson;
        }

        public string JsonSeriaLista(ListView lista) {

            var defaultVariables = JsonConvert.SerializeObject(lista, Formatting.Indented);
            return defaultVariables.Equals(defaultVariables);

        }

        public static Dispostivo JsonDesserializar(string Json)
        {
            return JsonConvert.DeserializeObject<Dispostivo>(Json);
        }

    }
}

But, i don’t receive give the correct result.
Any Idea to give the correct response?
