c# - Devexpress ASPXUploader UploadedFiles.Count 始终为 1

Question

void SaveFiles(out XElement Attachments)
    {
        Attachments = null;
        if (Uploader1.UploadedFiles.Count() > 0)
        {
            Attachments = new XElement("files");
            foreach (var file in Uploader1.UploadedFiles)
            {
                string ext = System.IO.Path.GetExtension(file.FileName).ToLower();
                string FileName = System.IO.Path.GetFileNameWithoutExtension(file.FileName) + "_" + Guid.NewGuid().ToString().Substring(0, 4) + ext;
                Attachments.Add(new XElement("file", FileName));
                file.SaveAs(AppDomain.CurrentDomain.BaseDirectory + "upload\\support\\" + FileName);
            }
        }
    }

和标记

<dx:ASPxUploadControl ID="Uploader1" runat="server" Width="280px">
    <AdvancedModeSettings EnableMultiSelect="True" />
</dx:ASPxUploadControl>

无论我选择多个文件，甚至这里什么都没有，计数总是 1。 通过 UploadedFiles 获取文件是否正确？

有必要处理ASPxUploadControl.FileUploadComplete事件并通过事件的参数检索发布的文件。
