    }

    public void HTMLToPdf(string HTML, string FilePath)

        Document document = new Document();

        PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\\Chap0101.pdf", FileMode.Create));
        document.Open();
        Image pdfImage = Image.GetInstance(Server.MapPath("logo.png"));

        pdfImage.ScaleToFit(100, 50);

        pdfImage.Alignment = iTextSharp.text.Image.UNDERLYING; pdfImage.SetAbsolutePosition(180, 760);

        document.Add(pdfImage);
        iTextSharp.text.html.simpleparser.StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
        iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
        hw.Parse(new StringReader(HTML));
        document.Close();
        ShowPdf("Chap0101.pdf");
    }
    private void ShowPdf(string s)
    {
        Response.ClearContent();
        Response.ClearHeaders();
        Response.AddHeader("Content-Disposition", "inline;filename=" + s);
        Response.ContentType = "application/pdf";
        Response.WriteFile(s);

推荐答案

 Dim jpeg As iTextSharp.text.Image
 Dim _Chunk As Chunk
jpeg = iTextSharp.text.Image.GetInstance(imagepath)
_Chunk = New Chunk(jpeg, 0, 0)
document.Add(_Chunk);

这会起作用！！！

谢谢
