我正在使用Json.Net将对象 Json 数据反序列化为对象/集合（列表）

我不确定我做错了什么，我试过这个：

List<LanguageObject> lang = JsonConvert.DeserializeObject<List<LanguageObject>>(jsonData);

并尝试了这个：

LanguageObject.Results lang = JsonConvert.DeserializeObject<LanguageObject.Results>(jsonData);

我收到此错误：

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[LanguageObject]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.   
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'meta', line 1, position 8.

这是我的Json：

{"meta":
{
    "status":200,
    "message":[],
    "resultSet":
          {"id":"05"},
    "pagination":     
     {
        "count":2,
        "pageNum":1,
        "pageSize":2,
        "totalPages":1,
        "sort":"ordinal",
        "order":"Asc",
        "currentUri":null,
        "nextUri":null
      }
    },
    "results":   
     {
         "id":0,
         "name":
         "Language",
         "DName":null,
         "qvalue":"language",
         "language":null,
         "mUsageCount":null,
         "Ordinal":0,
      "items":
         [
           {
             "id":0,
             "name":"English",
             "DName":"English",
             "qvalue":null,
             "language":null,
             "mUsageCount":null,
             "Ordinal":0,
             "items":[]
           },
           {
             "id":0,
              "name":"Spanish",
              "DName":"Spanish;",
              "qvalue":null,
              "language":null,
              "mUsageCount":null,
              "Ordinal":0,"
              items":[]
           }
         ]
     }}

语言对象.cs

   Public class LanguageObject
    {
    public class ResultSet
    {
        public string id { get; set; }
    }

    public class Pagination
    {
        public int count { get; set; }
        public int pageNum { get; set; }
        public int pageSize { get; set; }
        public int totalPages { get; set; }
        public string sort { get; set; }
        public string order { get; set; }
        public object currentUri { get; set; }
        public object nextUri { get; set; }
    }

    public class Meta
    {
        public int status { get; set; }
        public List<object> message { get; set; }
        public ResultSet resultSet { get; set; }
        public Pagination pagination { get; set; }
    }

    public class Item
    {
        public int id { get; set; }
        public string name { get; set; }
        public string DName { get; set; }
        public object qvalue { get; set; }
        public object language { get; set; }
        public object mUsageCount { get; set; }
        public int Ordinal { get; set; }
        public List<object> items { get; set; }
        public List<object> __invalid_name__
                      items { get; set; }
    }

    public class Results
    {
        public int id { get; set; }
        public string name { get; set; }
        public object DName { get; set; }
        public string qvalue { get; set; }
        public object language { get; set; }
        public object mUsageCount { get; set; }
        public int Ordinal { get; set; }
        public List<Item> items { get; set; }
    }

    public class RootObject
    {
        public Meta meta { get; set; }
        public Results results { get; set; }
    }

我没有看到LanguageObject您的问题中定义的类。但是，我确实看到了一RootObject堂课。根据您发布的内容，您需要像这样反序列化：

RootObject root = JsonConvert.DeserializeObject<RootObject>(jsonData);

然后你可以Results从RootObject：

Results lang = root.Results;
