打印时更改 PDF 文件名 - 另存为操作

Question

我在 iframe 窗口中显示 PDF 文件，我的下一个操作是使用 javascript 打印该 iframe。文件正在打印窗口中打开，但单击 - 在打印窗口中另存为 PDF 默认选项后，它在窗口对话框中显示 actionname( 方法名称) DownloadReport 作为文件名。我必须在 Windows 对话框中显示不同的文件名。在这里我正在打印员工 pdf 报告，我必须将文件名设置为employeeId。该怎么做？

下面是打印的javascript代码-

$('#printFrame').attr('src', "/Employee/DownloadReport?id=" + empid + "&isEmp=" + flag + "&act=print");

            $('#printFrame').load(function () {
                
                window.frames['frm'].focus();
                window.frames['frm'].print();
                
                
            });

使用此方法返回 Pdf 响应

   private FileResult ExportDocument(byte[] document, string format, string fileName, bool isInline)
        {
            string contentType;
            string disposition = (isInline) ? "inline" : "attachment";

            switch (format.ToLower())
            {
                case "docx":
                    contentType = "application/vnd.openxmlformats-officedocument.wordprocessingml.document";
                    break;
                case "xls":
                    contentType = "application/vnd.ms-excel";
                    break;
                case "xlsx":
                    contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                    break;
                case "mht":
                    contentType = "message/rfc822";
                    break;
                case "html":
                    contentType = "text/html";
                    break;
                case "txt":
                case "csv":
                    contentType = "text/plain";
                    break;
                case "png":
                    contentType = "image/png";
                    break;

                case "Jpeg":
                    contentType = "image/Jpeg";
                    break;
                default:
                    contentType = String.Format("application/{0};charset=utf-8", format);
                    break;
            }

            Response.AddHeader("Content-Disposition", String.Format("{0}; filename={1}", disposition, fileName));
            return File(document, contentType);
        }

你可以像这样使用它

return ExportDocument(fromFileOrMemoryStream.ToArray(), "pdf", "myCustomReportName", true);
