我是新来的，所以请原谅任何错误的正确问题程序！

基本上，我正在尝试从Pearson Dictionary Web API反序列化json数组。这是JSON（我删除了一些多余的results索引以节省空间）：

{
  "status": 200,
  "offset": 0,
  "limit": 10,
  "count": 10,
  "total": 47,
  "url": "/v2/dictionaries/ldoce5/entries?headword=test",
  "results": [
    {
      "datasets": [
        "ldoce5",
        "dictionary"
      ],
      "headword": "test",
      "homnum": 1,
      "id": "cqAFzDfHTM",
      "part_of_speech": "noun",
      "pronunciations": [
        {
          "audio": [
            {
              "lang": "British English",
              "type": "pronunciation",
              "url": "/v2/dictionaries/assets/ldoce/gb_pron/brelasdetest.mp3"
            },
            {
              "lang": "American English",
              "type": "pronunciation",
              "url": "/v2/dictionaries/assets/ldoce/us_pron/test1.mp3"
            }
          ],
          "ipa": "test"
        }
      ],
      "senses": [
        {
          "definition": [
            "a set of questions, exercises, or practical activities to measure someone's skill, ability, or knowledge"
          ],
          "examples": [
            {
              "audio": [
                {
                  "type": "example",
                  "url": "/v2/dictionaries/assets/ldoce/exa_pron/p008-001626298.mp3"
                }
              ],
              "text": "Did you get a good mark in the test ?"
            }
          ],
          "gramatical_examples": [
            {
              "examples": [
                {
                  "audio": [
                    {
                      "type": "example",
                      "url": "/v2/dictionaries/assets/ldoce/exa_pron/p008-000592041.mp3"
                    }
                  ],
                  "text": "We have a test on irregular verbs tomorrow."
                }
              ],
              "pattern": "test on"
            }
          ],
          "signpost": "exam"
        }
      ],
      "url": "/v2/dictionaries/entries/cqAFzDfHTM"
    }
  ]
}

以下是我用来反序列化上述内容的C＃代码：

class Program
    {
        static void Main(string[] args)
        {
            string word = "test";

            string sURL = "https://api.pearson.com:443/v2/dictionaries/ldoce5/entries?headword=" + word;

            WebClient client = new WebClient();
            string full = client.DownloadString(sURL);

            var final = JsonConvert.DeserializeObject<Dictionary>(full);

            Console.WriteLine(final.results[0].senses.definition);
        }
    }

    public class Dictionary
    {
        public Result[] results { get; set; }
    }

    public class Result
    {
        public string part_of_speech { get; set; }
        public Senses senses { get; set; }
    }

    public class Senses
    {
        public string definition { get; set; }
    }

出于某种原因，当我尝试运行它时，我收到了这个奇怪的错误：

无法将当前JSON数组（例如[1,2,3]）反序列化为类型 'TestingJson.Senses'因为类型需要JSON对象（例如 {“name”：“value”}）正确反序列化。要修复此错误将JSON更改为JSON对象（例如{“name”：“value”}）或更改反序列化类型为数组或实现集合的类型接口（例如ICollection，IList）就像List一样从JSON数组反序列化。也可以添加JsonArrayAttribute 到类型强制它从JSON数组反序列化。路径 'results [0] .senses'，第1行，第512位。

非常感谢帮助！

如果您正在与定义明确的内容（即绝大多数API）进行交互，那么您最好不要创建强类型对象而不是动态或字典。

在Visual Studio中，如果你去.mat，那么它将生成你需要的所有对象。

.mat
