用vb.net上传MVC 2

Question

I didn't find any answer on web with vb.net (I find millions of samples with c#) 我在vb.net上没有在网上找到任何答案（我在C＃中找到了数百万个示例）

I translated a sample controller to vb.net but doesn't upload 我将示例控制器翻译为vb.net，但未上传

My ResimController.vb 我的ResimController.vb

<AcceptVerbs(HttpVerbs.Post)>
Public Function Anasayfa(ByVal forms As FormCollection) As ActionResult

    Dim errors As Boolean = False
    If String.IsNullOrEmpty(forms("Resimx")) Then
        errors = True
        ModelState.AddModelError("Resimx", "error")
    Else
        Dim sFileName As String = forms("Resimx")

        Dim file = Request.Files("Resimx")
        ''file' is always null, and Request.Files.Count is always 0 ??? 
        If file IsNot Nothing Then 'This line always returns Nothing
            Dim buf As Byte() = New Byte(file.ContentLength - 1) {}
            'do stuff with the bytes 
            file.InputStream.Read(buf, 0, file.ContentLength)
        Else
            errors = True
            ModelState.AddModelError("Resimx", "error")
        End If
    End If
    If errors Then
        Response.Write("Failed")
        Return View()
    Else
        Response.Write("Success")
        Return View()
    End If

End Function

The Anasayfa.aspx page Anasayfa.aspx页

<%@ Page Title="" Language="VB" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

Answer 1

The AjaxControlToolkit registration in the beginning of your view and the missing action attribute on your form raise some serious suspicions about your design. 视图开始处的AjaxControlToolkit注册和表单上缺少的action属性引起了对设计的严重怀疑。 It seems that you are trying to use server side controls which is a no-no in ASP.NET MVC because they rely on viewstate and postback model. 似乎您正在尝试使用ASP.NET MVC中的禁忌服务器端控件，因为它们依赖于viewstate和postback模型。

Here's an example of how you could implement file uploads in MVC: 这是如何在MVC中实现文件上传的示例：

Controller: 控制器：

<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

View: 视图：

<%  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 %>

Answer 2

I am removing master page from project and uploading. 我正在从项目中删除母版页并上传。 I dont know what is wrong in my master page.. This is my master page.. 我不知道我的母版页有什么问题。这是我的母版页。

----------- Problem Fixed : added enctype="multipart/form-data" to form1 ------------- -----------已解决的问题：将enctype =“ multipart / form-data”添加到了form1 -------------
