RestSharp：无法将 'RestSharp.JsonArray' 类型的对象转换为类型“System.Collections.Generic.IDictionary”

Question

目前无法解决问题：无法将类型 'RestSharp.JsonArray' 的对象转换为类型 'System.Collections.Generic.IDictionary`2[System.String,System.Object -- 这个我可以在此处看到的错误，在响应本身中：

var response = client.Execute<ThirdPartySuggester>(request);

但是我得到的 NullReferenceExeption：

var name = response.Data.Name;

这是我的测试class:

    public class Class1
    {
        [Theory]
        [InlineData("apple", "en-us")]
        public void SearchTest(string searchPhrase, string language)
        {
            var client = new RestClient("https://test_site/api");
            var request = new RestRequest("/thirdparty/suggester?searchPhrase={search_key}&marketLocale={language_id}", Method.GET);
            request
                .AddUrlSegment("search_key", searchPhrase)
                .AddUrlSegment("language_id", language);
            var response = client.Execute<ThirdPartySuggester>(request);

            var name = response.Data.Name;
            var manufacturer = response.Data.Manufacturer;
            var deviceType = response.Data.DeviceType;
            var searchKey = response.Data.SearchKey;

.....

我得到的响应包含以下数据：

[
  {
    "name": "iPhone 7 Plus",
    "manufacturer": "Apple",
    "deviceType": "smartphone_tablet",
    "searchKey": "apple_iphone_7_plus"
  },
  {
    "name": "iPhone 4s",
    "manufacturer": "Apple",
    "deviceType": "smartphone_tablet",
    "searchKey": "apple_iphone_4s"
  },
  {
    "name": "iPhone 6",
    "manufacturer": "Apple",
    "deviceType": "smartphone_tablet",
    "searchKey": "apple_iphone_6"
  },
  {
    "name": "iPod Touch 8th Generation",
    "manufacturer": "Apple",
    "deviceType": "smartphone_tablet",
    "searchKey": "apple_ipod_touch_8th_generation"
  },
  {
    "name": "iPhone 7",
    "manufacturer": "Apple",
    "deviceType": "smartphone_tablet",
    "searchKey": "apple_iphone_7"
  }
]

这是我要反序列化的实现 class：

public class ThirdPartySuggester
{
    public string Name { get; set; }
    public string Manufacturer { get; set; }
    public string DeviceType { get; set; }
    public string SearchKey { get; set; }
}

伙计们，如果您能提供任何帮助，我将不胜感激！

Answer 1

您将返回一个 ThirdPartySuggester 数组，因此您需要指定一个列表：

var response = client.Execute<List<ThirdPartySuggester>>(request);

然后要访问它们，请使用循环

foreach (ThirdPartySuggester item in response.Data)
{
  //get each items properties
}

Answer 2

还有一种方法是创建包装 class

public  class ThirdPartySuggesters : List<ThirdPartySuggester> {}
var response = client.Execute<ThirdPartySuggesters>(request);
