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，以下代码正在将JSON反序列化为RootObject：
var objResponse1 = JsonConvert.DeserializeObject<RootObject>(response2.Content);
但是，我的代码现在抛出一个JSON.net异常：
未处理的类型异常 ＆＃39; Newtonsoft.Json.JsonSerializationException＆＃39;发生在 Newtonsoft.Json.dll
其他信息：无法反序列化当前的JSON对象 （例如{＆＃34; name＆＃34;：＆＃34; value＆＃34;}）进入类型 ＆＃39; System.Collections.Generic.List`1 [ProcessOpenRequests.Program + RootObject]＆＃39; 因为该类型需要一个JSON数组（例如[1,2,3]）来反序列化 正确。
要修复此错误，请将JSON更改为JSON数组（例如 [1,2,3]）或更改反序列化类型，使其成为正常的.NET type（例如，不是像整数这样的基本类型，不是集合类型 像数组或List一样，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，我已尝试以下内容根据此错误的其他StackOverflow帖子反序列化JSON字符串，但错误仍然存在：
var test = JsonConvert.DeserializeObject<List<RootObject>>(response2.Content);
非常感谢任何帮助。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Properties2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; }
}
答案 0 :(得分：3)
You are trying to deserialize your JSON into a List<RootObject>. That requires your JSON to be an array, but your JSON is not an array, JSON arrays begin and end with [ and ].
Try desalinizing to a RootObject instead.
var test = JsonConvert.DeserializeObject<RootObject>(response2.Content);
答案 1 :(得分：0)
所以，这就是发生的事情，我收到的JSON数据的API改变了RootObject，我之前引用了Properties2，我需要更改它以引用Properites。我还必须更改一堆整数现在接收空数据。我反序列化RootObject的原始代码（和Bruno Garcia的答案）再次有效。
