MVC2 HttpPostedFileBase object is always nothing

I tried to recreate the thousands of simple examples online, and I Fail everytime.

What am I doing wrong?

• Other.aspx

  <%@ Page Title="" Language="VB" MasterPageFile="~/Views/Shared/Site.Master"
  

  Inherits="System.Web.Mvc.ViewPage" %>

  <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent"
  

  runat="server"> Other

  <asp:Content ID="Content2" ContentPlaceHolderID="MainContent"
  

  runat="server">

      <h2>Upload A File</h2>
  
       <% Html.BeginForm("UploadFile", "Home")%>
         <input type="file" name="f" />
         <input type="submit" />
         <% Html.EndForm()%>
      </form>
  </asp:Content>
  

  • HomeController.vb

  _ Public Class HomeController Inherits System.Web.Mvc.Controller

      Function Index() As ActionResult
          ViewData("Message") = "Welcome to ASP.NET MVC!"
  
          Return View()
      End Function
  
      Function About() As ActionResult
          Return View()
      End Funct开发者_运维百科ion
  
      <HttpPost()> _
      Sub UploadFile(f As HttpPostedFileBase) <---Breakpoint here, f is always "Nothing"
  
          RedirectToAction("Other")
      End Sub
  
  
      Function Other() As ActionResult
          Return View()

You need to set the enctype HTML property for the form to multipart/form-data.
