Desirializing complex json

Question

I’m new around here and I’d like your help, I need to deserialize a json, to use in an Xamarin Forms application and I’m having difficulties, how to proceed in c#? follow the json below

{
  "RECORDS": [{
      "Codigo": "33338",
      "Descricao": "MOLA WIL 50-1 - TRAS RURAL - 57\/64",
      "PrecoVenda": 74.75,
      "Referencia": "WIL 50-1",
      "Grupo": "002",
      "GrupoDesc": "MAM WILLYS",
      "Categoria": 3,
      "CategoriaDesc": "Material Acabado - Molas",
      "Classe": "001",
      "ClasseDesc": "MOLAS",
      "NCM": "7320.10.00"
    },
    {
      "Codigo": "33339",
      "Descricao": "MOLA WIL 50-2 - TRAS RURAL - 57\/64",
      "PrecoVenda": 69,
      "Referencia": "WIL 50-2",
      "Grupo": "002",
      "GrupoDesc": "MAM WILLYS",
      "Categoria": 3,
      "CategoriaDesc": "Material Acabado - Molas",
      "Classe": "001",
      "ClasseDesc": "MOLAS",
      "NCM": "7320.10.00"
    }
  ]
}

I need to deserialize and play within a list to do Binding in the properties, method I’m using, follows

public async void Ler()
    {
       var json = await LerArquivo.CarregarArquivo("Catalogo.json");
       var Catalogos = JsonConvert.DeserializeObject<List<Catalogo>>(json);
    }

When executing my code I have this return

Answer 1

Create two classes with the following code:

public class Rootobject
{
    public RECORD[] RECORDS { get; set; }
}

public class RECORD
{
    public string Codigo { get; set; }
    public string Descricao { get; set; }
    public string PrecoVenda { get; set; }
    public string Referencia { get; set; }
    public string Grupo { get; set; }
    public string GrupoDesc { get; set; }
    public string Categoria { get; set; }
    public string CategoriaDesc { get; set; }
    public string Classe { get; set; }
    public string ClasseDesc { get; set; }
    public string NCM { get; set; }
}

now install the package Newtonsoft.Json - (Json.NET) and with that installation execute the following code:

var result = Newtonsoft
            .Json
            .JsonConvert
            .DeserializeObject<Rootobject>(File.ReadAllText("./data.json"));

in that case the variable result will contain the list you need. You can also make an adjustment in the field PrecoVenda changing its type to decimal.
