Convert HTML file to PDF file using ITextSharp

I'd like to accomplish the following:

Given the path name of an html file, and the desired pathname of a pdf file, convert the HTML file to PDF using ITextSharp. I've seen plenty of code samples which do close to this but not exactly what I need. I believe my solution will need to use the iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList() function but I'm having trouble getting this to work with an actual HTML file and outputting an actual PDF file.

public void GeneratePDF(string htmlFileName, string outputPDFFileName)
{...}

is the function I'd really like to get working properly.

Thanks in advance

Edit: Here's an example I've of what I've tried:

iTextSharp.text.Document doc = new Document();
        PdfWriter.GetInstance(doc, new FileStream(Path.GetFullPath("fromHTML.pdf"), FileMode.Create));

        doc.Open();

        try
        {
            List<IElement> list = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(File.ReadAllText(this.textBox1.Text)), null);
            foreach (IElement elm in list)
            {
                doc.Add(elm);
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

        doc.Close();

Note that textBox1.Text contains the full path name of the html file I'm trying to convert to pdf and I want this to get output to "fromHTML.pdf"

Thanks!
