我创建了以下RootObject类来映射JSON:
public class RootObject
{
public List<string> @class { get; set; }
public Properties2 properties { get; set; }
public List<Entity> entities { get; set; }
public List<object> actions { get; set; }
public List<Link> links { get; set; }
}
以前，以下代码用于将JSON反序列化为RootObject:
var objResponse1 = JsonConvert.DeserializeObject<RootObject>(response2.Content);
然而，我的代码现在抛出了一个JSON.net异常：
类型为的未处理异常中出现"Newtonsoft.Json.JsonSerializationException"Newtonsoft.Json.dll
附加信息：无法反序列化当前JSON对象（例如｛"name"："value"｝）转换为类型'System.Collections.Generic.List `1[ProcessOpenRequests.Program+RootObject]'因为该类型需要JSON数组（例如[1，2，3]）来反序列化正确地
要修复此错误，请将JSON更改为JSON数组（例如。[1，2，3]）或更改反序列化的类型，使其成为正常的.NET类型（例如，不是像integer这样的基元类型，不是集合类型像数组或列表），可以从JSON对象反序列化。JsonObjectAttribute也可以添加到类型中，以强制它从JSON对象反序列化。
现在，我已经尝试了以下方法，根据其他关于此错误的StackOverflow帖子对JSON字符串进行反序列化，但错误仍然存在：
var test = JsonConvert.DeserializeObject<List<RootObject>>(response2.Content);
如有任何帮助，我们将不胜感激。谢谢
*更新
这是实体类：
public class Entity
{
public List<string> @class { get; set; }
public string rel { get; set; }
public Properties2 properties { get; set; }
public Actions actions { get; set; }
}
这是属性2类：
public class Properties2
{
public int? id { get; set; }
public string name { get; set; }
public string description { get; set; }
public string created_at { get; set; }
public string updated_at { get; set; }
public int? creator_id { get; set; }
public string permissions { get; set; }
public int? comments_count { get; set; }
public bool is_current_user_commenter { get; set; }
public int? follows_count { get; set; }
public bool is_current_user_following { get; set; }
public int? flags_count { get; set; }
public bool is_current_user_flagger { get; set; }
public int? tags_count { get; set; }
public decimal average_rating { get; set; }
public object ratings_count { get; set; }
public List<ObjectField> object_fields { get; set; }
public List<ObjectFieldInstance> object_field_instances { get; set; }
public int? display_id { get; set; }
public List<object> foreign_ids { get; set; }
public string status { get; set; }
public string priority { get; set; }
public int? request_type_id { get; set; }
public int? geo_location_id { get; set; }
public int? workflow_node_id { get; set; }
public int? workflow_graph_id { get; set; }
public object completed_at { get; set; }
public string due_at { get; set; }
public string due_status { get; set; }
public int? client_id { get; set; }
public bool display_foreign_id { get; set; }
public int? api_source_id { get; set; }
public bool is_duplicate { get; set; }
public bool is_self_closure_allowed { get; set; }
public bool has_duplicates { get; set; }
public bool use_permission_matrix { get; set; }
public List<object> request_type_foreign_api_ids { get; set; }
public object primary_attachment_id { get; set; }
public int? attachments_count { get; set; }
public object primary_attachment { get; set; }
public ContactInfo contact_info { get; set; }
public GeoLocation geo_location { get; set; }
public string request_type_name { get; set; }
public string creator_display_name { get; set; }
public string api_source_name { get; set; }
}
您正试图将JSON反序列化为List<RootObject>。这需要您的JSON是一个数组，但您的JSON不是数组，JSON数组以[和]开头和结尾。
试着脱盐到RootObject。
var test = JsonConvert.DeserializeObject<RootObject>(response2.Content);
所以，发生了这样的事情，我从接收JSON数据的API更改了RootObject，我以前引用Properties2的地方，我需要将其更改为引用Properties。我还必须更改一组整数才能接收空数据。我反序列化RootObject的原始代码（以及Bruno Garcia的答案）再次有效。
