Step 1. 新增Controller及Action
以下程式碼為驗證使用，沒有進行任何安全過濾，請不要使用。
Imports System.IO
Namespace UpDownFileFromDBMvc
Public Class FileUploadAndSessionTestController
Inherits System.Web.Mvc.Controller
'
' GET: /FileUploadAndSessionTest/Upload
Function Upload()
Return View()
End Function
Function Upload(upfile As HttpPostedFileBase )
If upfile IsNot Nothing andalso upfile.ContentLength > 0 Then
Dim savePath As String = Path.Combine(Server.MapPath("~/Files/"), upfile.FileName)
upfile.SaveAs(savePath)
TempData("FileName") = upfile.FileName
End If
Return RedirectToAction("FileInfo")
End Function
Function FileInfo()
ViewBag.FileName = TempData("FileName")
Return View()
End Function
End Class
End Namespace
以上參考該網友提供程式碼，我所撰寫的VB程式碼。
Step 2. 新增Upload與FileInfo的View
Upload.aspx
<%@ Page Title="" Language="VB" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Upload
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Upload</h2>
<%Using Html.BeginForm("Upload", "FileUploadAndSessionTest", FormMethod.Post, New With {.enctype = "multipart/form-data"})%>
<%: Html.ValidationSummary(True)%>
File：<input id="upfile" name="upfile" type="file" value="" />
<br />
<input type="submit" value="Upload" />
<%End Using%>
</asp:Content>
FileInfo.aspx
<%@ Page Title="" Language="VB" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> FileInfo </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>FileInfo</h2> Upload File Nale: <%: ViewBag.FileName %> </asp:Content>
