文件HistoriqueController.cs：

public ActionResult Afficher(int b1,int b2, int b3, int e1, int e2, int e3)
         {
             double d1 = b1 * 10000 + b2 * 100 + b3;
             double d2 = e1 * 10000 + e2 * 100 + e3;
             ViewBag.Title = (d2 - d1).ToString();
             Parcours p = new Parcours(d1, d2);
             var model = p._segments;

             return View(model);
         }

我有错误：

The parameters dictionary contains a null entry for parameter 'b1' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Afficher(Int32, Int32, Int32, Int32, Int32, Int32)' in 'MvcApplication7.Controllers.HistoriqueController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Nom du paramètre : parameters
