我已经尝试了下面的代码，但也遇到了一个错误。我正在使用最新的DLL。

String strSelectUserListBuilder = @"<html><body>
                                <h1>My First Heading</h1>
                                <p>My first paragraph.</p>
                            </body>
                        </html>";
String htmlText = strSelectUserListBuilder.ToString();
List<IElement> htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(htmlText), null);

我得到了这个错误：

字典中不存在给定的关键字。

使用ITextsharp将Html导出为PDF

试试这个：

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();

让我们尝试下面的代码，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)
     {
         throw ex;
     }
 }
