    <br /><br />
    <div id = "FileUploadContainer">
        <!--FileUpload Controls will be added here -->
    </div>
    <br />
    <input id="ButtonAdd" type="button" value="add" onclick = "AddFileUpload()" />
    <asp:Button ID="btnUpload" runat="server" Text="Upload"  />
<asp:Label ID="lbl2" runat="server" ForeColor="Red"></asp:Label>

Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click
        For i As Integer = 0 To Request.Files.Count - 1
            Dim PostedFile As HttpPostedFile = Request.Files(i)
            If PostedFile.ContentLength > 0 Then
                Dim FileName As String = System.IO.Path.GetFileName(PostedFile.FileName)
                PostedFile.SaveAs(Server.MapPath("Files\img\") + FileName)

            Else
                lbl2.Text = "No images have been selected to upload "
            End If
        Next
    End Sub

<script type = "text/javascript">
       var counter = 0;

       function AddFileUpload() {
           var div = document.createElement('DIV');
           div.innerHTML = '<input id="file' + counter + '" name = "file' + counter + '" type="file" /><input id="Button' + counter + '" type="button" value="Remove" onclick = "RemoveFileUpload(this)" />';
           document.getElementById("FileUploadContainer").appendChild(div);
           counter++;
       }
       function RemoveFileUpload(div) {
           document.getElementById("FileUploadContainer").removeChild(div.parentNode);
       }
       $(document).ready(function () {
           AddFileUpload();
       });

   </script>

推荐答案

(文档).ready(功能(){ AddFileUpload(); }); </script>

(document).ready(function () { AddFileUpload(); }); </script>

我认为您的"mappath"需要以/开头以映射到应用程序根目录.除此之外，根据您模糊的描述，我不确定出什么问题或可能出什么问题.

I think your ''mappath'' needs to start with a / to map to the application root. Beyond that, based on your vague description, I''m not sure what''s going wrong or what the problem could be.
