iTextSharp "The document has no pages."

iTextSharp "The document has no pages."

The "The document has no pages" error can occur in iTextSharp when trying to manipulate a PDF document that has not been properly opened or created. Here are some potential causes and solutions to this error:

  • You have not created a new document object before adding content. To create a new document object, use the Document class, like this:
var document = new Document();
  • You have not opened the document before adding content. To open a document, you can create a PdfWriter object and pass it the Document object, like this:
var writer = PdfWriter.GetInstance(document, new FileStream("output.pdf", FileMode.Create)); document.Open();
  • You have not closed the document after adding content. To close the document, you can call the Close method of the Document object, like this:
document.Close();
  • You have not added any content to the document. To add content to the document, you can create a new Paragraph object and add it to the document using the Add method, like this:
var paragraph = new Paragraph("Hello, world!"); document.Add(paragraph);

By following these steps, you should be able to create a PDF document with content and avoid the "The document has no pages" error in iTextSharp.
