Newtonsoft.Json.JsonSerializationException: '無法反序列化當前的 JSON object (例如 {"name":"value"})

Question

我想將我的 json 代碼保存到 mongoDB。 但我沒有將它保存到 mongoDB。 我收到一個錯誤。我搜索了很多但無法弄清楚。

Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON object (eg {"name":"value"}) into type 'System.Collections.Generic.IList`1[KitapjetFormApp.Alias]' because the type requires a JSON array （例如 [1,2,3]）正確反序列化。 To fix this error either change the JSON to a JSON array (eg [1,2,3]) or change the deserialized type so that it is a normal .NET type (eg not a primitive type like integer, not a collection type like an數組或列表）可以從 JSON object 反序列化。 JsonObjectAttribute 也可以添加到類型中以強制它從 JSON object 反序列化。 路徑“用戶 [1].Documents.Document.Alias.Name”，第 43 行，position 19。

Myjson 代碼是

          }
        }
      }
    }
  ]
}

我的班級是

public class Alias
{
    public string Name { get; set; }
    public DateTime CreationTime { get; set; }

}
public class Document
{
    public string @type { get; set; }
    public IList<Alias> Alias { get; set; }

}
public class Documents
{
    public Document Document { get; set; }

}
public class User
{
    public string Identifier { get; set; }
    public string Title { get; set; }
    public string Type { get; set; }
    public DateTime FirstCreationTime { get; set; }
    public string AccountType { get; set; }
    public Documents Documents { get; set; }

}
public class MukellefRoot
{
    public IList<User> User { get; set; }

}

我的代碼是 mongodb 插件

using (StreamReader file = File.OpenText(@"C:\mukellef\mukellef.json"))
{
        JsonSerializer serializer = new JsonSerializer();
        MukellefRoot mukellefler = (MukellefRoot)serializer.Deserialize(file, typeof(MukellefRoot));
        var mukellef = mukellefler.User.ToList();
        mukellefCollectionItems.InsertMany(mukellef);
}

我找到了解決方案

using Newtonsoft.Json;

dynamic results = JsonConvert.DeserializeObject<dynamic>(YOUR_JSON);
