Como fazer o serialize e o Deserialize no visual studio?

[Lucas Moreira dos Santos]

Olá estou criando um aplicativo usando o Xamarin.Android, a resposta Json que obtenho ao chamar a API é essa:

{"consumerId":56704292158, "categoryId":1, "categoryDescription": "Pessoa", "firstName":"Ronaldo","lastName":"Scalizi Pecanha","fiscalDocuments":[{"fiscalDocument":{"documentType":"Brasil: nº CPF","cpf":18825966832}}],"gender":"M","emailAddress":"[email protected]","optIns":[{"optIn":{"brandName":"consul","acceptanceStatus":false}},{"optIn":{"brandName":"brastemp","acceptanceStatus":true}}],"communicationData":[{"communicationInfo":{"addressId":26506503,"phoneNumbers":[{"phoneNumber":{"phoneType":"mobilePhone","phoneNumber":1195099038}}],"streetAddress":"AVENIDA RANGEL PESTANA","streetNumber":674,"streetComplement":null,"streetDistrict":"JARDIM CRISTIANE","cityName":"SANTO ANDRE","stateCode":"SP","zipCode":"09185220","locationReferences":[{"locationReference":"Mercado"}],"countryCode":"BR"}},{"communicationInfo":{"addressId":2.563244E+7,"phoneNumbers":[{"phoneNumber":{"phoneType":"mobilePhone","phoneNumber":11960625256}},{"phoneNumber":{"phoneType":"homePhone","phoneNumber":1143199038}}],"streetAddress":"AVENIDA RANGEL PESTANA","streetNumber":674,"streetComplement":"CASA","streetDistrict":"JARDIM CRISTIANE","cityName":"SANTO ANDRE","stateCode":"SP","zipCode":"09185220","locationReferences":[{"locationReference":"Ao lado do deposito lua nova"}],"countryCode":"BR"}}]}

Eu só preciso inserir em um campo textview os campos firstName e lastName, aqui está o código que estou usando:

 

using System;

using System;
using Android.App;
using Android.Widget;
using Android.OS;
using RestSharp;
using Newtonsoft.Json;
using Android.Util;
using App4.Resources;
using Newtonsoft.Json.Linq;

namespace App4
{
    [Activity(Label = "App4", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity : Activity
    {
        EditText edtcpf;
        Button btnConsumer;
        TextView txtcpf;
        RestRequest cpf { get; set; }
        public RestClient consumer { get; set; }
        IRestResponse mensagemConsumer;
        TextView txtresposta;
        RestClient orderId { get; set; }
        RestRequest requestorderId { get; set; }
        IRestResponse answer { get; set; }
        IRestResponse answerorder { get; set; }
        TextView txtnome;
        public string raika;
        private string teamname;
        private JToken primeironome;

       protected override void OnCreate(Bundle bundle)
       {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);
            btnConsumer = FindViewById<Button>(Resource.Id.btnConsumer);
            edtcpf = FindViewById<EditText>(Resource.Id.edtcpf);
            txtcpf = FindViewById<TextView>(Resource.Id.txtcpf);
            txtresposta = FindViewById<TextView>(Resource.Id.txtresposta);
            txtnome = FindViewById<TextView>(Resource.Id.txtNome);
            btnConsumer.Click += BtnConsumer_Click;

        }

        private void BtnConsumer_Click(object sender, EventArgs e)
        {
            try
            {
                // API Consumer CPF

                consumer = new RestClient("https://qa.api-latam.whirlpool.com/v1.0/consumers");
                cpf = new RestRequest("/" + edtcpf.Text, Method.GET);
                cpf.AddHeader("Content-Type", "application/json; charset=utf-8");
                cpf.AddHeader("Authorization", "Bearer 70197e6c-d81b-384c-bb32-d69e8c10b101");
                mensagemConsumer = consumer.Execute(cpf);
                string nombre = Convert.ToString(mensagemConsumer.Content);
                Nome nome = new Nome();
                string json = JsonConvert.SerializeObject(mensagemConsumer.Content, Formatting.Indented);
                nome.firstName = mensagemConsumer.Content;

                Log.Info("info ",json);
                txtresposta.Text = json;

                //API Consumer Appliances
                orderId = new RestClient("https://qa.api-latam.whirlpool.com/v1.0/consumers/");
                requestorderId = new RestRequest("/"+ edtcpf.Text+ "/service-orders", Method.GET);
                requestorderId.AddHeader("Content-Type", "application/json; charset=utf-8");
                requestorderId.AddHeader("Authorization", "Bearer 70197e6c-d81b-384c-bb32-d69e8c10b101");
                answerorder = orderId.Execute(requestorderId);
                txtnome.Text = answerorder.Content;
                string respostaorder = Convert.ToString(answerorder);
                dynamic deserializado = JsonConvert.DeserializeObject(respostaorder);
            }
            catch (Exception)
            {
                throw;
            }
        }
    }
}

 

Aqui é a classe que criei para usar como base de programa

	using System.Collections.Generic;
	using System.Linq;
	using System.Text;

	using Android.App;
	using Android.Content;
	using Android.OS;
	using Android.Runtime;
	using Android.Views;
	using Android.Widget;

	namespace App4.Resources
	{
    	public class Nome
    	{
         	public string firstName { get; set;}
         	public string lastName { get; set; }
  	  }
	}

Como posso pegar apenas esses campos usando o serialize e o Deserialize?
