Сериализации и десериализации данных JSON, не может десериализовать JSON-объект текущего

---

Привет,

Я получил сообщение об ошибке, что мне нужно десериализовать json, поэтому я это сделал:

   var user = db.Users.Select(x => new RegisterBindingModel()
            {
                Id = x.Id,
                Email = x.Email,
                UserName = x.UserName,
                FirstName = x.FirstName,
                LastName = x.LastName,
                Age = x.Age
            });

            var a = user.ToList();
            var b = Json(new { Data = a, Total = a.Count() });
List<RegisterBindingModel> c = 
 JsonConvert.DeserializeObject<List<RegisterBindingModel>>(b.Content);

Что происходит из-за ошибки, так как формат json неверен, и я сделал следующее:

 var user = db.Users.Select(x => new RegisterBindingModel()
            {
                Id = x.Id,
                Email = x.Email,
                UserName = x.UserName,
                FirstName = x.FirstName,
                LastName = x.LastName,
                Age = x.Age
            });

            var a = user.ToList();
            var b = Json(new { Data = a, Total = a.Count() });
            string strserialize = JsonConvert.SerializeObject(b.Content);
            //var recordObject = JObject.Parse(b.Content);
            var v = b.Content.ToString();
List<RegisterBindingModel> c = 
JsonConvert.DeserializeObject<List<RegisterBindingModel>>(strserialize); 

И я получил первую ошибку, с которой столкнулся:
>>

Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[Project.Models.RegisterBindingModel]' 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) 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 'Data', line 1, position 8.'

Вот объект json:

{"Data":[{"Id":1,"Email":"AdminTest@gmail.com","UserName":"AdminTest",
"FirstName":"Admin","LastName":"Test","Age":23}],"Total":13}

Что я уже пробовал:

string strserialize = JsonConvert.SerializeObject("["+b.Content+"]");

Что сделало формат json таким:

"[{ Data = System.Collections.Generic.List`1[Project.Models.RegisterBindingModel],
  Total = 13 }]"

Я получил эту ошибку:

Newtonsoft.Json.JsonSerializationException: 'Error converting value "[{ Data = System.Collections.Generic.List`1[Project.Models.RegisterBindingModel],
  Total = 13 }]" to type 
  'System.Collections.Generic.List`1[Project.Models.RegisterBindingModel]'. Path 
  '', line 1, position 97.'

Также попробовал это сделать:

var c = JsonConvert.DeserializeObject <IDictionary<string, 
  RegisterBindingModel>> (strserialize);

И я получил:

Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Project.Models.RegisterBindingModel' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array. Path 'Data', line 1, position 9.'
