PDFsharp - Comment créer un 2ème page

Je ne peux pas trouver de la documentation dans PDFsharp à montrer comment ajouter une 2ème page à l'aide de C#!

Par exemple, plus de en VB6, j'utilise une méthode de création de fichiers PDF appelé mjwPDF. Pour indiquer que la page est fini

objPDF.PDFEndPage

Et de commencer une nouvelle page:

objPDF.PDFNewPage

Mon PDFsharp paramètres initiaux:

//Create a new PDF document
PdfDocument document = new PdfDocument();

//Create an empty page
PdfPage page = document.AddPage();
//page.Contents.CreateSingleContent().Stream.UnfilteredValue;

//Get an XGraphics object for drawing
XGraphics gfx = XGraphics.FromPdfPage(page);

Malheureusement dans PDFsharp je ne peux pas savoir comment démarrer/écrire sur une nouvelle page. Je vois ces commandes, mais ne peut pas obtenir une deuxième page commencé.

document.AddPage();
document.InsertPage();

J'ai essayé les deux, mais ma sortie continue à écrire sur la page 1, page 2.

Toutes les idées seraient grandement appréciés.

Voici le code:

private void buttonPrint_Click(object sender, EventArgs e)
{
//Create a new PDF document
PdfDocument document = new PdfDocument();
//Create an empty page
PdfPage page = document.AddPage();
//page.Contents.CreateSingleContent().Stream.UnfilteredValue;
//Get an XGraphics object for drawing
