Hi Angel,

UPDATE 23-05-2022:

The latest version of GemBox.Pdf includes the PdfPage.ConvertToForm method which can be used to append the content from one PDF page to another.

Here is a small example of how you can use it:

var form = document2.Pages[0].ConvertToForm(document1);
var group = document1.Pages[0].Content.Elements.AddGroup();
group.Elements.AddForm(form);
document1.Save("output.pdf");

ORIGINAL:

Please download the AddContent.zip project and take the GemBoxPdfExtensions.cs file within.
It defines an AddContent extension method that can append (or prepend) one PDF page into another.

Here is a small example how you can use that extension method:

using (var document1 = PdfDocument.Load("input1.pdf"))
using (var document2 = PdfDocument.Load("input2.pdf"))
{
    var page1 = document1.Pages[0];
    var page2 = document2.Pages[0];
    page1.AddContent(page2);

    document1.Save("output.pdf");
}

Mario
