Question

大家好，我有一个应用程序，我正在尝试获取Json数组响应并将其放入TextView，但它有5个计数，我不知道如何使用for来读取JsonArray的每个字段这是代码：

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);
            var requestToken = JsonConvert.DeserializeObject<RootObject>(answerorder.Content);
            var parse = JObject.Parse(answerorder.Content);
            var QtdeItens = parse.Count;
            var end = "";
            /*foreach (Dictionary<string, Order2> kvp in Order)
            {
                txtorder.Text = "Id: " + kvp.Value.orderId;

            }*/


        }
        catch (Exception)
        {

            throw;
        }




    }


}

}

我在http://json2csharp.com/创建了一个类，这是我用来获取值的类。 JSON答案取决于该人设置的身份证号码，因此每次使用ID 181.299.668-32

进行此测试时，它都会有所不同

using System;
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;
using Newtonsoft.Json;

public class Order2
{
public object 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; }
   }

所以json返回的答案是： { “订单”：[{ “顺序”：{ “订单ID”：7004093603， “orderStatusCode”： “CANC”， “orderStatusDescription”： “Cancelado”， “serviceProviderId”：3649， “orderOpeningDate”：“2015 - 07-07" ， “orderSchedulingDate”： “2015年7月18日”， “orderSchedulingPeriod”： “M”， “orderSettlementDate”：NULL， “orderCancellationDate”：空}}，{ “顺序”：{ “订单ID”：7004153791 “orderStatusCode”： “AGEN”， “orderStatusDescription”： “Agendado”， “serviceProviderId”：3524， “orderOpeningDate”： “2016年8月31日”， “orderSchedulingDate”： “2016年9月1日”， “orderSchedulingPeriod” ： “M”， “orderSettlementDate”：NULL， “orderCancellationDate”：空}}，{ “顺序”：{ “订单ID”：7004156972， “orderStatusCode”： “ABRT”， “orderStatusDescription”： “Aberto”， “serviceProviderId” ：30820 “orderOpeningDate”： “2017年4月13日”， “orderSchedulingDate”：NULL， “orderSchedulingPeriod”：NULL， “orderSettlementDate”：NULL， “orderCancellationDate”：空}}，{ “顺序”：{ “订单ID” ：7002178478， “orderStatusCode”： “CANC”， “orderStatusDescription”： “Cancelado”， “serviceProviderId”：3555， “orderOpeningDate”： “2014年2月22日”， “orderSchedulingDate”：“2014年2月2日4" ， “orderSchedulingPeriod”： “M”， “orderSettlementDate”：NULL， “orderCancellationDate”：空}}，{ “顺序”：{ “订单ID”：7002118317， “orderStatusCode”： “CANC”， “orderStatusDescription”：” Cancelado”， “serviceProviderId”：3555， “orderOpeningDate”： “2014年2月10日”， “orderSchedulingDate”： “2014年2月15日”， “orderSchedulingPeriod”： “M”， “orderSettlementDate”：空， “orderCancellationDate”日期null}}]}

并且JsonViewer表示它有5个计数，所以我怎样才能执行for或foreach来读取orderId，orderStatus代码，orderStatusDescription和orderOpeningDate，因为它依赖于Id从0到10计数

[编辑]

使用方法：

foreach (var order in requestToken.orders)
            {

                    object vader = order.order.orderId;
                    string darth = Convert.ToString(vader);
                    txtorder.Text = darth;
                    txtorder.Text = order.order.orderStatusDescription;
                    txtorder.Text = order.order.orderStatusCode.;
               }

它返回了一个orderId :)。我的疑问是：它自动调用计数0的 orderId 如何调用其他orderIds？是这样的吗？

               foreach (var order in requestToken.orders)
            {
                //for (var i = 0; i < requestToken.orders.Count; i++)
                //{
                    object vader = order.order.orderId[1], [2], etc;
                    string darth = Convert.ToString(vader);
                    txtorder.Text = darth;
                    txtorder.Text = order.order.orderStatusDescription;
                    txtorder.Text = order.order.orderStatusCode.;
                //}

谢谢你们帮助我

Answer 1

您可以访问以下值：

var test = JsonConvert.DeserializeObject<Rootobject>(json);
var orderIds = new List<long>();
foreach (var order in test.orders)
{
    var vader = order.order.orderId;
    orderIds.Add(vader);
}

请注意，在循环的每次迭代中，orderIds都会被覆盖到vader变量。如果要保留它们，则需要一个集合（在我的示例中名为orderIds的列表），并在每次迭代中添加到该集合。最后，所有orderId都位于orderIds。

Answer 2

您需要反序列化JSON字符串

var data = JsonConvert.DeserializeObject<RootObject>(jsonString);

然后运行foreach循环

foreach(var orders in data)
{
    var Id = orders.order.orderId;
    ///and so on...
}
