                Type PDFType = Type.GetTypeFromProgID("AcroExch.App");

                CAcroApp AcroAppObj = Activator.CreateInstance(PDFType) as CAcroApp;

                AcroAppObj.Show();

                CAcroAVDoc AvDocObj = AcroAppObj.GetActiveDoc() as CAcroAVDoc;

                CAcroPDDoc PdDocObj = AvDocObj.GetPDDoc() as CAcroPDDoc;

                Console.WriteLine(PdDocObj.GetNumPages());

                Console.WriteLine(PdDocObj.GetInfo(PdDocObj.GetFileName()));

                string fileName = PdDocObj.GetFileName();

                I can get the file name, but how can I get the full path?
