doc.Save(outputName, Aspose.Words.SaveFormat.Pdf);

The “.docx” file is attached.

How to resolve this problem?

Hi Yuan,

Thanks for your inquiry. Perhaps, you are using an older version of Aspose.Words; as with Aspose.Words v15.9.0, I am unable to reproduce this problem on my side. I would suggest you please upgrade to the latest version of Aspose.Words i.e. v15.9.0 and let us know how it goes on your side. I hope, this will help.
