让我们试试下面的代码，它将帮助您将 HTML 转换为 PDF 文件。
String strSelectUserListBuilder = @"<html><body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>";
String htmlText = strSelectUserListBuilder.ToString();
CreatePDFFromHTMLFile(htmlText , pdfFileName);
public void CreatePDFFromHTMLFile(string HtmlStream, string FileName)
{
try
{
object TargetFile = FileName;
string ModifiedFileName = string.Empty;
string FinalFileName = string.Empty;
/* To add a Password to PDF -test */
TestPDF.HtmlToPdfBuilder builder = new TestPDF.HtmlToPdfBuilder(iTextSharp.text.PageSize.A4);
TestPDF.HtmlPdfPage first = builder.AddPage();
first.AppendHtml(HtmlStream);
byte[] file = builder.RenderPdf();
File.WriteAllBytes(TargetFile.ToString(), file);
iTextSharp.text.pdf.PdfReader reader = new iTextSharp.text.pdf.PdfReader(TargetFile.ToString());
ModifiedFileName = TargetFile.ToString();
ModifiedFileName = ModifiedFileName.Insert(ModifiedFileName.Length - 4, "1");
string password = "password";
iTextSharp.text.pdf.PdfEncryptor.Encrypt(reader, new FileStream(ModifiedFileName, FileMode.Append), iTextSharp.text.pdf.PdfWriter.STRENGTH128BITS, password, "", iTextSharp.text.pdf.PdfWriter.AllowPrinting);ss
reader.Close();
if (File.Exists(TargetFile.ToString()))
File.Delete(TargetFile.ToString());
FinalFileName = ModifiedFileName.Remove(ModifiedFileName.Length - 5, 1);
File.Copy(ModifiedFileName, FinalFileName);
if (File.Exists(ModifiedFileName))
File.Delete(ModifiedFileName);
}
catch (Exception ex)

Try this:
尝试这个：
Document document = new Document();
PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\MySamplePDF.pdf", FileMode.Create));
document.Open();
iTextSharp.text.html.simpleparser.HTMLWorker hw =
new iTextSharp.text.html.simpleparser.HTMLWorker(document);
hw.Parse(new StringReader(htmlText));
document.Close();
