PdfFileInfo fileInfo = new PdfFileInfo(LocalFileName);
fileInfo.SetMetaInfo("comments", "This is test comment");



Hi Arun,

If you’re trying to add new custom property, you can use PdfXmpMetadata class. You can also find the details in this article:


However, if you’re trying to update an existing custom property and it is not working at your end the please share the sample PDF file. We’ll need to test the issue at your end. You’ll be updated accordingly.

We’re sorry for the inconvenience.
