+You can get the information about the PDF output file using the [GetViewInfo](https://reference.groupdocs.com/viewer/net/groupdocs.viewer/viewer/methods/getviewinfo) method that returns a [ViewInfo](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.results/viewinfo) object. The object contains the [Pages](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.results/viewinfo/pages/) collection that represents each [Page](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.results/page/) of the document.

+using (Viewer viewer = new Viewer("sample.pdf"))
