C# ASP.NET Get method with parameter returning 404

Question

Good afternoon, folks, I was wondering if anyone could assist me. My Web Service has a Get method that returns the entire list of Products, however I would like to create a method that it returns ONE Product according to a code that passed to it. At the moment all the method with parameter is returning me is a 404 when tested on Fiddler. Any idea? Any methods you have? any help is welcome thanks.

Code:

[Route("api/Produto")]
public class ProdutoConsultController : ApiController
{


    // GET api/ProdutoConsult
    public ObjectResult<uspConsultarProduto_Result> Get()
    {
        ControleDeEstoqueEntities entity = new ControleDeEstoqueEntities();
        var result = entity.uspConsultarProduto(null);
        return result;
    }

    // GET api/ProdutoConsult/5
    public List<produto> Get(int cod)
    {
        ControleDeEstoqueEntities entity = new ControleDeEstoqueEntities();
        List<produto> MyList = new List<produto>();
        var result = from produto in entity.produto where produto.pro_cod == cod select produto;
        MyList.AddRange(result);

        return MyList;
    }

The attribute Route is not being used properly.

You should use them in actions and not in controller, in the controller one should use RoutePrefix to set a "prefix" for the route.

public class ProdutoConsultController : ApiController
{
    [Route("api/Produto")]
    public ObjectResult<uspConsultarProduto_Result> Get()
    {
        // Retornar todos
    }

    [Route("api/Produto/{cod}")]
    public List<produto> Get(int cod)
    {
        // retornar um
    }
}
