vb.net上传文件的问题 [英] vb.net upload file problem

问题描述

当我尝试发布一个文件时，它返回false，即没有附加文件。任何人都可以看到这个问题吗？或者可能导致它。

When I try to post a file its coming back false ie there was no file attached. Can anyone see anything wrong with this? Or what might be causing it.

<form id="Form1" enctype="multipart/form-data" method="post" runat="server">
    <asp:FileUpload ID="fileUpload" runat="server" />
    <asp:Button ID="cmdSubmitApplication" runat="server" Text="Button" />
</form>

Protected Sub cmdSubmitApplication_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdSubmitApplication.Click

    If Me.fileUpload.PostedFile Is Nothing Then
        Response.Write("You must specify file to upload!")
    Else

        Try

            Dim strExt As String = Path.GetExtension(Me.fileUpload.PostedFile.FileName)

            If strExt.ToLower() = ".doc" Then

                Dim savedFile As String
                savedFile = Path.GetFileName(Me.fileUpload.PostedFile.FileName)
                Me.fileUpload.PostedFile.SaveAs(Server.MapPath("cvs\") & savedFile)
                Response.Write("File Uploaded Successfully")

            Else
                Response.Write("Only Image Files are Allowed")
            End If

        Catch exp As Exception
            Response.Write(exp.Message)
        End Try

    End If

End Sub

推荐答案

修好了。主人有一个标签，所以我下面添加的表单是嵌套的。我删除了主表单标签。会导致其他地方的问题吗？我应该删除上面的表单标签，而不是主。

fixed it. There was a tag in the master, so the form I added below was nested. I removed the form tag from the master. Would that cause problems elsewhere. Should I just remove the form tag above instead of the master.

ps我讨厌vb.net和它的一切。

ps I hate vb.net and everything about it.
