Clone or import pages between PDF documents in C# and VB.NET

With GemBox.Pdf, you can clone or import pages (and even page trees) between PDF documents in your C# or VB.NET application.

It's possible to duplicate an entire PdfDocument, using the PdfDocument.Clone() method, or just a specific page using the PdfPages.AddClone() method. For more information about cloning in GemBox.Pdf, see the Document Structure help page.

The following example shows how you can clone pages from another PDF document.
