I am trying to add custom property on PDF using below code.
My PDF is located in tempDir.
Aspose.Pdf.Facades.PdfFileInfo fInfo = new Aspose.Pdf.Facades.PdfFileInfo(tempDir + strNewFileName +".pdf");
If I try to get the Custom Property information at this stage it works fine.
But if the PDF file is uploaded and then downloaded again , and if I try to retrieve the property value then it is blank.
fInfo.GetMetaInfo(“processFile”) is blank
Is there anything missing ?
How to ensure that Custom Properties are not lost ?
