Json.NET和RESTSharp-轉換值時出錯

Question

我創建了一個API，現在嘗試通過另一個應用程序進行訪問。 即使我使用Newtonsoft.JSON對JSON進行序列化和反序列化，也遇到了以下InnerException轉換錯誤：

{"Could not cast or convert from System.String to System.Collections.Generic.List`1[MidamAPI.Models.ManagerDTO]."}

以下是引發錯誤的代碼段（在RESTFactory中）：

     public List<T> Execute<T>(String endPoint) where T : new() {
        RestClient client = new RestClient(BASE_URL);

        IRestRequest req = new RestRequest(endPoint);
        req.AddHeader("Authorization", "Bearer " + this._token);
        var response = client.Execute(req).Content;
        List<T> responseData = JsonConvert.DeserializeObject<List<T>>(response);

        return responseData;
    }

在這里稱為：

{
        RegisterViewModel vm = new RegisterViewModel();
        RESTFactory factory = new RESTFactory((String)Session["bearer"]);
        vm.availableManager = factory.Execute<ManagerDTO>("managers");
        vm.availableProperties = factory.Execute<PropertyDTO>("locations");
        vm.availableTrainers = factory.Execute<TrainerDTO>("trainers");

        return View(vm);
    }

該信息來自以下API控制器操作（在單獨的應用程序中）：

    [LocalFilter]
[RoutePrefix("managers")]
public class ManagersController : ApiController
{
    UnitOfWork worker = new UnitOfWork();

       [Route("")]
    public string Get()
    {
        IEnumerable<ManagerDTO> dtoList = Mapper.Map<List<Manager>, List<ManagerDTO>>(worker.ManagerRepo.Get().ToList());

        foreach (ManagerDTO dto in dtoList)
        {
            Manager manager = worker.ManagerRepo.GetByID(dto.ID);
            dto.Stores = (Mapper.Map<IEnumerable<Property>, IEnumerable<PropertyDTO>>(manager.Properties)).ToList();
        }

        return JsonConvert.SerializeObject(dtoList);
    }

兩種應用中的DTO相同：

{
public class ManagerDTO
{
    public int ID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public List<PropertyDTO> Stores { get; set; }
}




  public class PropertyDTO
{
    public int ID;
    public string ShortName { get; set; }
    public string Street { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Zip { get; set; }
    public string Phone { get; set; }
    public string Lat { get; set; }
    public string Long { get; set; }
    public string GooglePlaceID { get; set; }
    public string PropertyNumber { get; set; }
    public int ManagerID { get; set; }
    public int TrainerID { get; set; }

    public string ManagerName { get; set; }
    public string ManagerEmail { get; set; }
    public string TrainerEmail { get; set; }

}

我嘗試將json2csharp工具與響應一起使用，一切似乎對我來說都很好：

public class Store
{
    public int ID { get; set; }
    public string ShortName { get; set; }
    public string Street { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string Zip { get; set; }
    public string Phone { get; set; }
    public string Lat { get; set; }
    public string Long { get; set; }
    public string GooglePlaceID { get; set; }
    public string PropertyNumber { get; set; }
    public int ManagerID { get; set; }
    public int TrainerID { get; set; }
    public string ManagerName { get; set; }
    public string ManagerEmail { get; set; }
    public object TrainerEmail { get; set; }
}

public class RootObject
{
    public int ID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public List<Store> Stores { get; set; }
}

任何意見，將不勝感激。

編輯：

RegisterViewModel類公共類RegisterViewModel {

    public RegistrationDTO regModel { get; set; }
    public List<ManagerDTO> availableManager { get; set; }
    public List<PropertyDTO> availableProperties { get; set; }
    public List<TrainerDTO> availableTrainers { get; set; }
}

使您的控制器的Get（）返回類型為IHttpActionResult

並返回Ok（dtoList）;
