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.
using System;
using GemBox.Pdf;
class Program
{
static void Main()
{
// If using the Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");
using (var document = PdfDocument.Load("%InputFileName%"))
{
int pageCount = %PagesCount%;
// Load a source document.
using (var source = PdfDocument.Load("%#LoremIpsum.pdf%"))
{
// Get the number of pages to clone.
int cloneCount = Math.Min(pageCount, source.Pages.Count);
// Clone the requested number of pages from the source document
// and add them to the destination document.
for (int i = 0; i < cloneCount; i++)
document.Pages.AddClone(source.Pages[i]);
}
document.Save("Cloning.pdf");
}
}
}Imports System
Imports GemBox.Pdf
Module Program
Sub Main()
' If using the Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY")
Using document = PdfDocument.Load("%InputFileName%")
Dim pageCount As Integer = %PagesCount%
' Load a source document.
Using source = PdfDocument.Load("%#LoremIpsum.pdf%")
' Get the number of pages to clone.
Dim cloneCount = Math.Min(pageCount, source.Pages.Count)
' Clone the requested number of pages from the source document
' and add them to the destination document.
For i As Integer = 0 To cloneCount - 1
document.Pages.AddClone(source.Pages(i))
Next
End Using
document.Save("Cloning.pdf")
End Using
End Sub
End Module
