Answer 1

The problem may be invalid html. One way to check is to run your html source through a validator such W3C Markup Validation Service .

have you already tried to add a Page with:

pdfDoc.NewPage();

I think your Code should look like this:

byte[] data;
using (var sr = new StringReader(sw.ToString()))
{
    var st = new StyleSheet();

    GetStyleSheetForUnicodeCharacters(st);
    using (var ms = new MemoryStream())
    {
        using (var pdfDoc = new Document())
        {                            
            using (var w = PdfWriter.GetInstance(pdfDoc, ms))
            {
               pdfDoc.Open();
               pdfDoc.NewPage(); // add Page here
               var parsedHtmlElements = HTMLWorker.ParseToList(sr, st);
               foreach (var htmlElement in parsedHtmlElements)
               {
                  pdfDoc.Add(htmlElement as IElement);
               }
               pdfDoc.Close();
               data = ms.ToArray();
            }
        }
    }
}

You can also add a blank Page by using:

    pdfDoc.newPage();
    w.setPageEmpty(false);

Need to check that any html tags are mismatched. Example /td>, this types of mistake raised above error.
