【问题描述】:
我使用 Xamarin 为 Android 编写应用程序。
我尝试制作回收站视图。
这是我的 json:http://pastebin.com/rL214a2T
我有这样的课程:
public class Billing
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_1 { get; set; }
public string address_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postcode { get; set; }
public string country { get; set; }
public string email { get; set; }
public string phone { get; set; }
}
public class Shipping
{
public string first_name { get; set; }
public string last_name { get; set; }
public string company { get; set; }
public string address_1 { get; set; }
public string address_2 { get; set; }
public string city { get; set; }
public string state { get; set; }
public string postcode { get; set; }
public string country { get; set; }
}
public class Result
{
public int id { get; set; }
public int parent_id { get; set; }
public string status { get; set; }
public string order_key { get; set; }
public int number { get; set; }
public string currency { get; set; }
public string version { get; set; }
public bool prices_include_tax { get; set; }
public string date_created { get; set; }
public string date_modified { get; set; }
public int customer_id { get; set; }
public string discount_total { get; set; }
public string discount_tax { get; set; }
public string shipping_total { get; set; }
public string shipping_tax { get; set; }
public string cart_tax { get; set; }
public string total { get; set; }
public string total_tax { get; set; }
//public List<Billing> billing { get; set; }
public Billing billing { get; set; }
public Shipping shipping { get; set; }
public string payment_method { get; set; }
public string payment_method_title { get; set; }
public string transaction_id { get; set; }
public string customer_ip_address { get; set; }
public string customer_user_agent { get; set; }
public string created_via { get; set; }
public string customer_note { get; set; }
public string date_completed { get; set; }
public string date_paid { get; set; }
public string cart_hash { get; set; }
public List<object> line_items { get; set; }
public List<object> tax_lines { get; set; }
public List<object> shipping_lines { get; set; }
public List<object> fee_lines { get; set; }
public List<object> coupon_lines { get; set; }
public List<object> refunds { get; set; }
}
public class RootObject
{
public List<Result> results { get; set; }
}
我这样写课:
using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
using ModernHttpClient;
using Newtonsoft.Json;
namespace StarWars.Api.Repository
{
public class MoviesRepository
{
public async Task<RootObject> GetAllFilms()
{
var httpClient = GetHttpClient();
var response = await httpClient.GetAsync(ServiceEndPoints.StartWarsApiBaseUri).ConfigureAwait(false);
if (response.IsSuccessStatusCode)
{
var content = response.Content;
string jsonString = await content.ReadAsStringAsync().ConfigureAwait(false);
return JsonConvert.DeserializeObject<RootObject>(jsonString);
}
return new RootObject();
}
private HttpClient GetHttpClient()
{
var httpClient = new HttpClient(new NativeMessageHandler())
{
BaseAddress = new Uri(ServiceEndPoints.StartWarsApiBaseUri)
};
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
return httpClient;
}
}
public class ServiceEndPoints
{
public static readonly string StartWarsApiBaseUri = "http://api.simplegames.com.ua/index.php/?wc_orders=processing_orders";
// public static readonly string GetFilmsUri = "films";
}
}
但是当我尝试启动应用程序时出现此错误
Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'StarWars.Api.Repository.RootObject' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
据我所知,我需要设置
我该如何解决?
更新
使用 Resharper 我重新制作这样的代码
public async Task<List<RootObject>> GetAllFilms()
{
var httpClient = GetHttpClient();
var response = await httpClient.GetAsync(ServiceEndPoints.StartWarsApiBaseUri).ConfigureAwait(false);
if (response.IsSuccessStatusCode)
{
var content = response.Content;
string jsonString = await content.ReadAsStringAsync().ConfigureAwait(false);
return JsonConvert.DeserializeObject<List<RootObject>>(jsonString);
}
return new List<RootObject>();
}
private HttpClient GetHttpClient()
{
var httpClient = new HttpClient(new NativeMessageHandler())
{
BaseAddress = new Uri(ServiceEndPoints.StartWarsApiBaseUri)
};
httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
return httpClient;
}
}
public class ServiceEndPoints
{
public static readonly string StartWarsApiBaseUri = "http://api.simplegames.com.ua/index.php/?wc_orders=processing_orders";
// public static readonly string GetFilmsUri = "films";
}
}
但我在这一行的 MainActivity 中有错误 var moviesAdapter = new MovieAdapter(films.results)
这里是错误
错误 CS1061“列表”不包含“结果”的定义,并且找不到接受“列表”类型的第一个参数的扩展方法“结果”(您是否缺少 using 指令或程序集引用?)

你能分享你的json吗?
