您好我正在使用Xamarin來處理android。我編寫了一個代碼來從WSO2調用API，它返回的答案取決於用戶發送的ID。它返回的內容這樣的JSON：如何使用.Text序列化和反序列化Json var

{ 「consumerId」：56704292158， 「的categoryId」：1， 「categoryDe​​scription」： 「佩索阿」， 「名字」： 「FN」，」 lastName「，」fiscalDocuments「：[{」fiscalDocument「：{」documentType「：」Brasil：nºCPF「，」cpf「：199999992}}]，」gender「：」M「，」emailAddress「 ： 「：R **** @ * COM」， 「optIns」：[{ 「選擇啓用」：{ 「名優產品」： 「領事」， 「acceptanceStatus」：假}}，{ 「選擇啓用」：{ 「名優產品」： 「brastemp」， 「acceptanceStatus」：真}}]， 「communicationData」：[{ 「communicationInfo」：{ 「addressId」：2 **** 03， 「PHONENUMBERS」：[{ 「phoneNumber的」：{ 「PHONETYPE」： 「mobilePhone」，「phoneNumber」：5555555555}}]，「streetAddress」：「ANY STREET」，「streetNumber」：123，「streetComplement」：null，「streetDistrict」：「AN Y城市「，」cityName「：」ANY CITY「，」stateCode「：」XX「，」zipCode「：」12345「，」locationReferences「：[{」locationReference「：」Mercado「}]，」countryCode「 ZZ 「}}，{」 communicationInfo 「：{」 addressId 「：2.563244E + 7」，PHONENUMBERS 「：[{」 phoneNumber的 「：{」 PHONETYPE 「：」 mobilePhone 「 」phoneNumber的「：5555555555}}，{」 phoneNumber的「：{」phoneType「：」homePhone「，」phoneNumber「：555555555}}]，」streetAddress「：」ANY STREET「，」streetNumber「：123，」streetComplement「：」CASA「，」streetDistrict「 「，」cityName「：」ANY CITY「，」stateCode「：」XX「，」zipCode「：」12345「，」locationReferences「：[{」locationReference「：」Ao lado do deposito lua nova「}] 「：」ZZ「}}]}

我只想從這個字段獲取firstName和lastName。我試圖序列化這個，但我認爲我做錯了什麼。下面是代碼

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; 
      } 
     } 
    } 
}

這裏是獲取類，並設置

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; } 
    } 
}

我如何序列化和與使用取決於像。文本一edtcpf.Text一個變種反序列化JSON這及其內容？

我只想得到從這個字段firstName和lastName。

對於這個要求，你可以在你的項目中安裝Newtonsoft.Json package再例如：

TextView tvfirst = FindViewById<TextView>(Resource.Id.firstname); 
TextView tvlast = FindViewById<TextView>(Resource.Id.lastname); 

Button btn = FindViewById<Button>(Resource.Id.btn); 
btn.Click += (sender, e) => 
{ 
    var jsonstring = @"{'consumerId':56704292158, 'categoryId':1, 'categoryDescription': 'Pessoa', 'firstName':'FN','lastName':'Last Name','fiscalDocuments':[{'fiscalDocument':{'documentType':'Brasil: nº CPF','cpf':199999992}}],'gender':'M','emailAddress':'r****@*.com','optIns':[{'optIn':{'brandName':'consul','acceptanceStatus':false}},{'optIn':{'brandName':'brastemp','acceptanceStatus':true}}],'communicationData':[{'communicationInfo':{'addressId':'lalala','phoneNumbers':[{'phoneNumber':{'phoneType':'mobilePhone','phoneNumber':5555555555}}],'streetAddress':'ANY STREET','streetNumber':123,'streetComplement':null,'streetDistrict':'ANY TOWN','cityName':'ANY CITY','stateCode':'XX','zipCode':'12345','locationReferences':[{'locationReference':'Mercado'}],'countryCode':'ZZ'}},{'communicationInfo':{'addressId':2.563244E+7,'phoneNumbers':[{'phoneNumber':{'phoneType':'mobilePhone','phoneNumber':5555555555}},{'phoneNumber':{'phoneType':'homePhone','phoneNumber':555555555}}],'streetAddress':'ANY STREET','streetNumber':123,'streetComplement':'CASA','streetDistrict':'ANY TOWN','cityName':'ANY CITY','stateCode':'XX','zipCode':'12345','locationReferences':[{'locationReference':'Ao lado do deposito lua nova'}],'countryCode':'ZZ'}}]}"; 
    JToken token = JObject.Parse(jsonstring); 

    var firstname = token.SelectToken("firstName"); 
    tvfirst.Text = firstname.ToString(); 
    var lastname = token.SelectToken("lastName"); 
    tvlast.Text = lastname.ToString(); 
};

我用了兩個TextView顯示名字和姓氏項目，並使用一個按鈕來解析json字符串。

並且通過拷貝你的JSON文件，似乎在你的JSON文件中的錯誤與節點addressId，你可以使用一些Json的格式來格式化你的JSON字符串，然後就可以看到這個問題。我將其改爲「lalala」，以便在我的示例中進行測試。

首先你需要檢查這是否是一個有效的json。根據我的分析，它有一些錯誤，如姓氏。您可以使用該網站來驗證https://jsonformatter.curiousconcept.com/

此JSON是在一個陌生的方式構成的，而是由創建它擁有的所有對象，你可以使用它像這樣：

using System; 
using System.Collections.Generic; 
using Newtonsoft.Json; 

namespace teste { 
    class MainClass { 
     public static void Main(string[] args) { 

      var jsonString = @"{'consumerId':56704292158, 'categoryId':1, 'categoryDescription': 'Pessoa', 'firstName':'FN','lastName':'Last Name','fiscalDocuments':[{'fiscalDocument':{'documentType':'Brasil: nº CPF','cpf':199999992}}],'gender':'M','emailAddress':'r * ***@*.com','optIns':[{'optIn':{'brandName':'consul','acceptanceStatus':false}},{'optIn':{'brandName':'brastemp','acceptanceStatus':true}}],'communicationData':[{'communicationInfo':{'addressId':'2****03','phoneNumbers':[{'phoneNumber':{'phoneType':'mobilePhone','phoneNumber':5555555555}}],'streetAddress':'ANY STREET','streetNumber':123,'streetComplement':null,'streetDistrict':'ANY TOWN','cityName':'ANY CITY','stateCode':'XX','zipCode':'12345','locationReferences':[{'locationReference':'Mercado'}],'countryCode':'ZZ'}},{'communicationInfo':{'addressId':'2.563244','phoneNumbers':[{'phoneNumber':{'phoneType':'mobilePhone','phoneNumber':5555555555}},{'phoneNumber':{'phoneType':'homePhone','phoneNumber':555555555}}],'streetAddress':'ANY STREET','streetNumber':123,'streetComplement':'CASA','streetDistrict':'ANY TOWN','cityName':'ANY CITY','stateCode':'XX','zipCode':'12345','locationReferences':[{'locationReference':'Ao lado do deposito lua nova'}],'countryCode':'ZZ'}}]}"; 

      JsonSerializerSettings jsonSerializerSettings = new JsonSerializerSettings { 
       NullValueHandling = NullValueHandling.Ignore, 
       MissingMemberHandling = MissingMemberHandling.Ignore 
      }; 

      Pessoa pessoa = JsonConvert.DeserializeObject<Pessoa>(jsonString, jsonSerializerSettings); 

      Console.WriteLine(pessoa.FirstName); 
      Console.WriteLine(pessoa.LastName); 
     } 
    } 

    public class Pessoa { 
     public long ConsumerId { get; set; } 
     public int CategoryId { get; set; } 
     public string CategoryDescription { get; set; } 
     public string FirstName { get; set; } 
     public string LastName { get; set; } 
     public List<FiscalDocumentData> FiscalDocuments { get; set; } 
     public string Gender { get; set; } 
     public string EmailAddress { get; set; } 
     public List<OptInData> OptIns { get; set; } 
     public List<CommunicationData> CommunicationData { get; set; } 
    } 

    public class OptInData { 
     public OptInInfo OptIn { get; set; } 
    } 

    public class OptInInfo { 
     public string BrandName { get; set; } 
     public bool AcceptanceStatus { get; set; } 
    } 

    public class FiscalDocumentData { 
     public FiscalDocumentInfo FiscalDocument {get; set; } 
    } 

    public class FiscalDocumentInfo { 
     public string DocumentType { get; set; } 
     public long Cpf { get; set; } 
    } 

    public class CommunicationData { 
     public CommunicationInfo CommunicationInfo { get; set; } 
    } 

    public class CommunicationInfo { 
     public string AddressId { get; set; } 
     public List<PhoneInfo> PhoneNumbers { get; set; } 
     public string StreetAddress { get; set; } 
     public int StreetNumber { get; set; } 
     public string StreetComplement { get; set; } 
     public string StreetDistrict { get; set; } 
     public string CityName { get; set; } 
     public string StateCode { get; set; } 
     public string ZipCode { get; set; } 
     public List<Reference> LocationReferences { get; set; } 
     public string CountryCode { get; set; } 
    } 

    public class Reference { 
     public string LocationReference { get; set; } 
    } 

    public class PhoneInfo { 
     public PhoneNumberInfo PhoneNumber { get; set; } 
    } 

    public class PhoneNumberInfo { 
     public string PhoneType { get; set; } 
     public long PhoneNumber { get; set; } 
    } 
}
