c＃中的JSON解析问题

Question

我正在使用以下代码来解析JSON。我有例外。

using System.Collections.Generic;
using Newtonsoft.Json;
using RestSharp;
using WebAutomation.BDD.Data;
namespace WebAutomation.Utils
{
    public class RestApi
    {
        private static IRestResponse HttpGetResponse(string endPoint)
        {
            var client = new RestClient(endPoint);
            var request = new RestRequest(Method.GET);
            return client.Execute(request);
        }
        public static FeaturedMenuItems GetFeaturedMenuItems()
        {
            var a = HttpGetResponse("http://<DOMAIN>/api/web/menu/quick");
            return JsonConvert.DeserializeObject<FeaturedMenuItems>(a.Content);
        }
    }
}

我正在使用以下课程来解析：

using System.Collections.Generic;
namespace WebAutomation.BDD.Data
{
    public class FeaturedMenu
    {
        public string MenuItemName { get; set; }
        public string MenuItemName_en { get; set; }
        public string MenuItemName_zh { get; set; }
        public string url { get; set; }
        public string LastModifiedDate { get; set; }
    }
    public class FeaturedMenuItems
    {
        public List<FeaturedMenu> Featured_Menu { get; set; }
    }
}

这是我得到的JSON：

    "Featured_Menu": [

        "MenuItemName-en": "Today's Racing",

  }

我得到以下例外：

newtonsoft.json.jsonserializationException：' 当前的JSON数组（例如[1,2,3]） 'webautomation.bdd.data.featuredmenuitems'，因为该类型需要一个 json对象（例如{" name"：" value"}）正确序列化。修理 此错误要么将JSON更改为JSON对象（例如 {" name"：" value"}）或将避难类型更改为数组或一个 键入实现集合接口（例如Icollection，iList）的类型 喜欢从JSON阵列中进行的列表。 JSONARRAYATTRIBUTE也可以添加到该类型中，以将其强加于 从JSON阵列中进行挑选。路径''，第1行，位置1。'

我无法弄清楚这个问题。任何帮助都将不胜感激。

Answer 1

您正在尝试对FeaturedMenuItems的数组进行挑选，而不是单个FeaturedMenuItems。尝试使用：

JsonConvert.DeserializeObject<FeaturedMenuItems[]>(a.Content)
