Question

您好，我有以下代码，从中我想获得一些字段并放入Android.TextView

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;
using Org.Json;
using System.Net;
using System.IO;
using System.Collections.Generic;

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 txtsobrenome;
    RestClient orderId { get; set; }
    RestRequest requestorderId { get; set; }
    IRestResponse answerorder { get; set; }
    TextView txtnome;
    TextView txtorder;
    TextView txtmensagem;

    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);
        txtsobrenome = FindViewById<TextView>(Resource.Id.txtresposta);
        txtnome = FindViewById<TextView>(Resource.Id.txtNome);
        txtorder = FindViewById<TextView>(Resource.Id.txtorder);
        txtmensagem = FindViewById<TextView>(Resource.Id.txtMensagem);
        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);
            Pessoa pessoa = JsonConvert.DeserializeObject<Pessoa>(mensagemConsumer.Content);
            txtnome.Text = "Nome: " +pessoa.firstName;
            txtsobrenome.Text = "Sobrenome: "+ pessoa.lastName;

            // 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);
            CustomerJson json = JsonConvert.DeserializeObject<List<CustomerJson>>(json);
            txtorder.Text = json.Customer.orderId;





        }
        catch (Exception)
        {

            throw;
        }




    }


}

}

我正在尝试反序列化一个数组的JsonResponse，这是我从API获得的响应：

**{
  "orders": [
   {
  "order": {
    "orderId": 7004093603,
    "orderStatusCode": "CANC",
    "orderStatusDescription": "Cancelado",
    "serviceProviderId": 3649,
    "orderOpeningDate": "2015-07-07",
    "orderSchedulingDate": "2015-07-18",
    "orderSchedulingPeriod": "M",
    "orderSettlementDate": null,
    "orderCancellationDate": null
  }
},
{
  "order": {
    "orderId": 7004153791,
    "orderStatusCode": "AGEN",
    "orderStatusDescription": "Agendado",
    "serviceProviderId": 3524,
    "orderOpeningDate": "2016-08-31",
    "orderSchedulingDate": "2016-09-01",
    "orderSchedulingPeriod": "M",
    "orderSettlementDate": null,
    "orderCancellationDate": null
  }
},
{
  "order": {
    "orderId": 7004156972,
    "orderStatusCode": "ABRT",
    "orderStatusDescription": "Aberto",
    "serviceProviderId": 30820,
    "orderOpeningDate": "2017-04-13",
    "orderSchedulingDate": null,
    "orderSchedulingPeriod": null,
    "orderSettlementDate": null,
    "orderCancellationDate": null
  }
},
{
  "order": {
    "orderId": 7002178478,
    "orderStatusCode": "CANC",
    "orderStatusDescription": "Cancelado",
    "serviceProviderId": 3555,
    "orderOpeningDate": "2014-02-22",
    "orderSchedulingDate": "2014-02-24",
    "orderSchedulingPeriod": "M",
    "orderSettlementDate": null,
    "orderCancellationDate": null
  }
},
{
  "order": {
    "orderId": 7002118317,
    "orderStatusCode": "CANC",
    "orderStatusDescription": "Cancelado",
    "serviceProviderId": 3555,
    "orderOpeningDate": "2014-02-10",
    "orderSchedulingDate": "2014-02-15",
    "orderSchedulingPeriod": "M",
    "orderSettlementDate": null,
    "orderCancellationDate": null
    }
    }
    ]
    }**

我创建了一个包含此字符串的类

 class RootObject
{
 [JsonProperty("orders")]
public Results Results { get; set; }
}

class Results
{
[JsonProperty("order")]
public Dictionary<string, JobCode> JobCodes { get; set; }
}

class JobCode
{
[JsonProperty("orderId")]
public string orderId { get; set; }
[JsonProperty("orderStatusCode")]
public string orderStatusCode { get; set; }
[JsonProperty("orderStatusDescription")]
public string orderStatusDescription { get; set; }
  }

我需要插入到applicative中的字段是orderId orderStatusCode和orderStatusDescription。

我正在尝试对其进行反序列化，但它会返回以下消息：参数1：无法从'CustomerJson'转换为'string'并使用未分配的局部变量'json'

如何反序列化？

Answer 1

重要事项

1）Order是orders [] array的子元素。

2）客户是订单的子元素。

你应该使用enumarator，循环等逐步搜索oders []数组......然后，当每个循环都完成时，你应该在order元素中解析Customer类。

实施例

foreach(var order in orders)
{ 
   var order = order.name;
   //access to order data;
}

Deserialize JSON to C# Classes

Answer 2

您的json不正确，您错过了＆＃39;}＆＃39;。这是有效的json

{
  "orders": [{
    "order": {
        "orderId": 7004093603,
        "orderStatusCode": "CANC",
        "orderStatusDescription": "Cancelado",
        "serviceProviderId": 3649,
        "orderOpeningDate": "2015-07-07",
        "orderSchedulingDate": "2015-07-18",
        "orderSchedulingPeriod": "M",
        "orderSettlementDate": null,
        "orderCancellationDate": null
    }
  }]
}

另外，我使用http://json2csharp.com/创建了模型，我将它们粘贴在下面。尝试用以下模型解析你的json，它应该可以工作

public class Order2 {
  public long orderId { get; set; }
  public string orderStatusCode { get; set; }
  public string orderStatusDescription { get; set; }
  public int serviceProviderId { get; set; }
  public string orderOpeningDate { get; set; }
  public string orderSchedulingDate { get; set; }
  public string orderSchedulingPeriod { get; set; }
  public object orderSettlementDate { get; set; }
  public object orderCancellationDate { get; set; }
}

public class Order{
  public Order2 order { get; set; }
}

public class RootObject{
  public List<Order> orders { get; set; }
}
