Question

在ASP.NET C＃网站/服务器中，我使用名为ITextSharp的.pdf创建程序库来创建带有text＆amp;的.pdf文件。一些关于产品的图片。

像往常一样，老板不想购买许可证。我知道如果我使用ITextSharp版本4.1.6或更低版本，我可以使用免费许可证下的库（我不能吗？）

我的问题：旧版本（4.1.6 - ）/免费版本是否满足我生成pdf的需求，其中顶部是图像，中间是文本内容（某些段落），底部的图像？我会找到一些自己无法使用的API函数，因为我有旧版本吗？

您是否建议我转到另一个开源ASP.NET C＃.pdf生成器？

Answer 1

是的，您也可以使用旧版本。我附加了使用字符串生成器的代码，用mysxt生成html。

Document doc = new Document(PageSize.LETTER, 10, 10, 42, 35);
                iTextSharp.text.pdf.PdfWriter wri = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, new FileStream("D:\\PurchaseOrderDetails.pdf", FileMode.Create));
                doc.Open();//
                StringBuilder builder = new StringBuilder();
                builder.Append("<html>");
                builder.Append("<head>");
                builder.Append("</head>");
                builder.Append("<body>");
                builder.Append("<img src=\"D:\\Images\\logo_left.png\" align=\"right\"/>");
                builder.Append("<br/><br/><br/><br>");
                builder.Append("");
                builder.Append("<h1 style=\"font-weight: bold\">Purchase Order Details</h1> ");
                builder.Append("");
                builder.Append("<br /><br /> ");
                builder.Append("<h2 style=\"font-weight: bold\">Purchase Order Information</h2> ");
                builder.Append("<table> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">P.O.Number:</td> ");
                builder.Append("      <td>" + txtPONumber.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Vendor:</td> ");
                builder.Append("      <td>" + txtVendorName.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Entry Date:</td> ");
                builder.Append("      <td>" + dtpickerEntryDate.SelectedDate + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Description:</td> ");
                builder.Append("      <td>" + txtDescription.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Ship Method:</td> ");
                builder.Append("      <td>" + drpShipMethod.SelectedItem.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Ship Carrier:</td> ");
                builder.Append("      <td>" + drpShipCarrier.SelectedItem.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Price:</td> ");
                builder.Append("      <td>" + txtPrice.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Shipping Cost:</td> ");
                builder.Append("      <td>" + txtShippingCost.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Warranty Status:</td> ");
                builder.Append("      <td>" + txtWarrantyStatus.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("   <tr> ");
                builder.Append("      <td style=\"font-weight: bold\">Part Requirement:</td> ");
                builder.Append("      <td>" + drpPartRequirement.SelectedItem.Text + "</td> ");
                builder.Append("   </tr> ");
                builder.Append("</table> ");
                builder.Append("<br /><br /> ");
                builder.Append(" ");
                builder.Append("<p style=\"text-align: center; font-style: italic; font-size: 10pt\"> ");
                builder.Append("   Thank you for your business! If you have any questions about your order, please contact us at ");
                builder.Append("   800-555-. ");
                builder.Append("</p> ");
                builder.Append("</body>");
                builder.Append("</html>");

                var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(builder.ToString()), null);
                foreach (var htmlElement in parsedHtmlElements)
                    doc.Add(htmlElement as IElement);

                doc.Close();
