Error in htmlparser cannot take string reader as input?

Question

In the following code, Parse cannot take StringReader (sr) as input. How can I pass the string I have to Parse, then?

protected void LinkButton1_Click(object sender, EventArgs e)
{
    Response.ContentType = "application/pdf";
    Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);          

    string str = "<h1 title=’Header’ align=’Center’> Writing To PDF Using ASP.NET> <br><table align=’Center’><tr><td style=’width:100px;color:green’> <b>iTextSharp</b></td><td style=’width:100px;color:red’>mytestpdf</td></tr></table>";
    StringReader sr = new StringReader(str);
    Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0.0f);
    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
    pdfDoc.Open();
    htmlparser.Parse(sr);//Parse cannot take input as string reader (sr) how to solve?
    pdfDoc.Close();
    Response.Write(pdfDoc);
    Response.End();
}

And the question is? Oh, I see the question burried in the code. Please reformat the question to make it more readable. See [Ask] and [FAQ] page for more information. — Steve B, Apr 22 '14 at 13:37

What version of .net are you targeting and what version of iTextSharp are you using? — Chris Haas, Apr 23 '14 at 01:01

Why are you putting your html into a StringReader? You already have the html in a string, just use that.

htmlparser.Parse(str)

If you must use StringReader for some reason, use the ReadToEnd() method to get a data type HTMLWorker.Parse will accept:

htmlparser.Parse(sr.ReadToEnd())
