Aspose.Slides

Aspose.Slides for .NET allows developers to manage the hyperlinks in presentation on the presentation, slide and text frame level.The IHyperlinkQueries class helps to manage hyperlinks in a presentation.


 string FilePath = @"..\..\..\..\Sample Files\";

string FileName = FilePath + "Get all the External Eyperlinks.pptx";

//Instantiate a Presentation object that represents a PPTX file

Presentation pres = new Presentation(FileName);

//Get the hyperlinks from presentation

IList<IHyperlinkContainer> links = pres.HyperlinkQueries.GetAnyHyperlinks();

foreach (IHyperlinkContainer link in links)

    Console.WriteLine(link.HyperlinkClick.ExternalUrl);
