title: Add a page to PDF document using iTextSharp
body: <p>I would like to add a page to an existing PDF document containing simple text.</p>
  
  <p>I have tried the following code that I found on the internet, but so far I haven't got it to work:</p>
  
  <pre><code>PdfReader reader = new PdfReader("1.pdf");
  Document document = new Document(reader.GetPageSize(1));
  PdfCopy copier = new PdfCopy(doc, new FileStream("2.pdf", FileMode.Create));
  
  for (int pageCounter = 1; pageCounter &lt; reader.NumberOfPages + 1; pageCounter++)
  {
      //byte[] page = reader.GetPageContent(pageCounter);
      copier.AddPage(copier.GetImportedPage(reader, pageCounter));
  }
  
  copier.NewPage();
  copier.Add(new Paragraph("This is added text"));
  
  document.Close();
  reader.Close();
  </code></pre>
  
  <p>Please let me know how to do this right?</p>
