Show dynamically created PDF on website

[[email protected]]

I am showing a mailmerge document converted to PDF on my website.

Would you check this code to see if this is the best way to do it please?

Code: Select all

public ActionResult ShowPDFOnWebsite(int psfAppID)
{
   var resourcePath = ReflectionUtil.GetManifestResourceStreamNameByFileName("PsfApplicationTemplate.docx");
   var assembly = Assembly.GetExecutingAssembly();
   using (Stream stream1 = assembly.GetManifestResourceStream(resourcePath))
   {
      var data = _PsfAppReportUtil.GetModelAsDataTable(_EfContext, psfAppID);
      var doc = new Spire.Doc.Document(stream1);
      doc.MailMerge.HideEmptyParagraphs = true;
      doc.MailMerge.Execute(data);

      var stream2 = new MemoryStream();
      doc.SaveToStream(stream2, Spire.Doc.FileFormat.PDF);
      var pdfDoc = new PdfDocument(stream2);
      pdfDoc.SaveToHttpResponse("test.pdf", System.Web.HttpContext.Current.Response, HttpReadType.Open);
      return null;
   }
}
