I took a project already developed, but with several problems. In the controller that I am working on, I put a break in the constructor with a parameter and does not enter. If I define one without parameter and keep the other(with parameter), break stops in no without parameter and not in with parameter. The scenario looked like this: 1) The injection was being made by an object and not an interface, as is common. Is it possible to inject an object? My testing solution was: I commented on everything, created an interface with a method, in the Budget class, and injected it into the controller’s constructor, but that didn’t work either. See the controller as it is:
[ApiVersion("1")]
[RoutePrefix("orders")]
[Description("doc0x03303001")]
public class OrdersController : ApiController
{
private readonly OrdersManager _mng;
//public OrdersController(){}
public OrdersController(OrdersManager mng)
{
if (mng == null)
throw new ArgumentNullException(nameof(mng));
_mng = mng;
}
[HttpGet]
public IHttpActionResult GetTeste()
{
_mng.ReceiveAssessment("ok", "ok", "ok", 1);
return Ok("");
}
}
The Receiveassessment method is this(only to test whether or not you enter the method)
public void ReceiveAssessment(string assessment, string claimNumber, string registerNumber, int code)
{
string _assessment = assessment;
string _claimnumber = claimNumber;
string _registernumber = registerNumber;
int _code = code;
}
below the Ordersmanager
public class OrdersManager : IDisposable, IOrdersManager
{
private OrdersManagement _mng;
private OrderDist _orderDist;
private SystemAssessment _systemAssessment;
private BlackListSupplier _blacklistsuplier;
public OrdersManager(string idUser, string login, string timezone,
string idCompany, string idCompanyType)
{
_mng = new OrdersManagement(idUser, login, timezone, idCompany, idCompanyType);
}
public void ReceiveAssessment(string assessment, string claimNumber, string registerNumber, int code)
{
string _assessment = assessment;
string _claimnumber = claimNumber;
string _registernumber = registerNumber;
int _code = code;
}
#region IDisposable Support
private bool disposedValue = false; // To detect redundant calls
protected virtual void Dispose(bool disposing)
{
if (!disposedValue)
{
if (disposing)
{
// TODO: dispose managed state (managed objects).
}
// TODO: free unmanaged resources (unmanaged objects) and override a finalizer below.
//TODO: SSO
//_mng?.Dispose();
// TODO: set large fields to null.
disposedValue = true;
}
}
// TODO: override a finalizer only if Dispose(bool disposing) above has code to free unmanaged resources.
~OrdersManager()
{
// Do not change this code. Put cleanup code in Dispose(bool disposing) above.
Dispose(false);
}
// This code added to correctly implement the disposable pattern.
public void Dispose()
{
// Do not change this code. Put cleanup code in Dispose(bool disposing) above.
Dispose(true);
// TODO: uncomment the following line if the finalizer is overridden above.
GC.SuppressFinalize(this);
}
#endregion
}
Ordersmanager is an object, as I reported above. How do I enter the controller and continue running the API?
The errors are concatenated in a class (an array of errors) and below I put them, taken in the settings passed above, and I call the Getteste action and do not receiveassessment.

When the compiler skips the constructor with parameters, it falls here first:
protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request,
CancellationToken cancellationToken)
{
var responseMessage = await base.SendAsync(request, cancellationToken);
object contentVal;
if (!responseMessage.TryGetContentValue(out contentVal))
return responseMessage;
if (contentVal == null)
return responseMessage;
ConvertDateTimeDeep(contentVal);
var processedResponse = request.CreateResponse(responseMessage.StatusCode, contentVal);
responseMessage.Content = processedResponse.Content;
return responseMessage;
}
In the above method, in the line var responseMessage = await base.SendAsync(request, cancellationToken); already explodes the stauscode 500(Internal Server Error). Already the var(Object) contentVal is where I get the errors and when I call ConvertDateTimeDeep passing contentVal, already Zica everything. I just wanted to understand why he does not enter the Builder.
Convertdatetimedeep
private void ConvertDateTimeDeep(object contentVal)
{
var scannedObjects = new HashSet<object>(new[] { contentVal });
var userTimeZone = HttpContext.Current.GetUserTimeZone();
if (typeof(IDictionary<object, object>).IsAssignableFrom(contentVal.GetType()))
{
var collection = (contentVal as IDictionary<object, object>).Values;
foreach (var item in collection)
ConvertDateTimeDeep(item, userTimeZone, scannedObjects);
}
else if (typeof(IDictionary<string, object>).IsAssignableFrom(contentVal.GetType()))
{
var collection = (contentVal as IDictionary<string, object>).Values;
foreach (var item in collection)
ConvertDateTimeDeep(item, userTimeZone, scannedObjects);
}
else if (typeof(IEnumerable<object>).IsAssignableFrom(contentVal.GetType()))
{
var enumerable = contentVal as IEnumerable<object>;
foreach (var item in enumerable)
ConvertDateTimeDeep(item, userTimeZone, scannedObjects);
}
else
ConvertDateTimeDeep(contentVal, userTimeZone, scannedObjects);
}
When I change the route on the controller to this
[Route("api/v1/[controller]")]
[Description("doc0x03303001")]
public class OrdersController : ApiController
{
private readonly OrdersManager _mng;
private readonly IOrdersManager _mngs;
//public OrdersController(){}
public OrdersController(IOrdersManager mng)
{
if (mng == null)
throw new ArgumentNullException(nameof(mng));
_mngs = mng;
}
}

include an example of the post you’re doing
– Leandro Angelo
@Leandroangelo, this is the call on the Postman:
http://localhost:24253/api/v1/orders/receiveassessment– pnet
You don’t have this route in your controller
– Leandro Angelo
Changing course, I caught this mistake: An error occurred when trying to create a controller of type 'Orderscontroller'. Make sure that the controller has a parameterless public constructor.
– pnet
In the edition of the errors, I said that there were 4 errors, but in fact it is one, only the class sepaou, but the mistake is one. Read all at once and not error 1, error 2 and etc. I will edit and put as if it were a single error
