PDF comparison returns no results in .NET


I am testing your compare api based on sample project GroupDocs.Comparison.Examples.CSharp.

The Compare method is returning no results. Any idea?

Please see also my screen shots.

Hi Muhammad ,

Thank you I got the temp license but unfortunately only sample pdf files in sample project get compared.

If I try any other pdf files to compare against each other causes no result.

Any idea?


Hi David ,

Thank you for your inquiry,

We are unable to reproduce this issue at our end. Comparison with other files is working fine. kindly share your sample source and target file and also share sample code if you are using your custom code. This will help us to re-produce this issue at our-end.

Thank you for your cooperation.

Warm Regards,
