Le AjaxControlToolkit regis La description au début de votre vue et l'attribut d'action manquant sur votre formulaire soulèvent de sérieux soupçons sur votre conception. Il semble que vous essayez d'utiliser les contrôles côté serveur, ce qui est un non-non dans ASP.NET MVC, car ils reposent sur le modèle viewstate et postback.

Voici un exemple de la façon dont vous pouvez implémenter le téléchargement de fichiers dans MVC:

Controller:

<HandleError()> _ 
Public Class HomeController 
    Inherits System.Web.Mvc.Controller 

    Function Index() As ActionResult 
     Return View() 
    End Function 

    <HttpPost()> 
    Function Index(ByVal Resimx As HttpPostedFileBase) As ActionResult 
     If Not Resimx Is Nothing Then 
      ' A file has been selected => do something with the uploaded file 
     End If 
     Return View() 
    End Function 
End Class

Vue:

<% Using Html.BeginForm("Index", "Home", Nothing, FormMethod.Post, New With { .enctype = "multipart/form-data" })%> 
    <input id="Resimx" name="Resimx" type="file" /> 
    <input type="submit" value="Upload" /> 
<% End Using %>

Merci pour la réponse Darin. Renvoie Rien de nouveau. – Ramazan

Qu'est-ce qui ne retourne rien? Pourriez-vous être un peu plus précis? J'ai testé mon exemple de code avant de l'afficher et cela a bien fonctionné. –

je retire la page principale du projet et le téléchargement. Je ne sais pas ce qui ne va pas dans ma page principale .. C'est ma page principale ..

Problème ----------- Correction: ajout enctype = "multipart/form-data" pour former1 -------------
