我正在使用以下代码使用 .iTextSharp 5.4.3 版生成 PDF。

// Create a Document object
        var document = new Document(PageSize.A4, 50, 50, 25, 25);

        // Create a new PdfWriter object, specifying the output stream
        var output = new MemoryStream();
        var writer = PdfWriter.GetInstance(document, output);

        // Open the Document for writing
        document.Open();

string data = @"<table cellspacing="0" border="0" style="border-collapse:collapse;margin-top:30px;;">
         <tr>
             <td></td><td>Visit</td><td></td><td></td><td></td>
        </tr><tr>
             <th>Datw</th><td>07/01/2013</td><td>07/18/2013</td><td>07/17/2013</td><td>07/09/2013</td>
        </tr><tr>
             <th>Score</th><td>3.00</td><td>6.33</td><td>1.00</td><td>8.00</td>
        </tr><tr>
             <th>Heading</th><td>7.0</td><td>8.0</td><td>2.0</td><td>3.0</td>
        </tr><tr>
             <th>Minutes</th><td>88</td><td>n/a</td><td>22</td><td>n/a</td>
        </tr><tr>
             <th>Test Data</th><td>5.0</td><td>8.0</td><td>4.0</td><td>3.0</td>
        </tr><tr>
             <th>Status</th><td>8.0</td><td>8.0</td><td>3.0</td><td>3.0</td>
        </tr><tr>
             <th>Data </th><td>3.96</td><td>6.88</td><td>5.83</td><td>6.67</td>
        </tr><tr>
             <th>Assessment (0-10)</th><td>5.0</td><td>3.0</td><td>2.0</td><td>2.0</td>
        </tr><tr>
             <th class="seperator">With heading</th><td>n/a</td><td>n/a</td><td>n/a</td><td>n/a</td>
        </tr>
    </table>";



        IElement ele;
        PdfPTable t;
        var stringWriter = new StringWriter();

        StyleSheet styles = new StyleSheet();
        styles.LoadStyle("seperator", "border-top", "#a9a9a9 2px solid");

        List<IElement> htmlarraylist = HTMLWorker.ParseToList(new StringReader(data), styles);
        for (int k = 0; k < htmlarraylist.Count; k++)
        {
            ele = htmlarraylist[k];

            document.Add(ele);
            //document.Add((IElement)htmlarraylist[k]);
        }


        document.Close();

        Response.ContentType = "application/pdf";
        Response.AddHeader("Content-Disposition", "attachment;filename=Receipt-test.pdf");
        Response.BinaryWrite(output.ToArray());

在生成 PDF 时，它没有应用样式。它也没有以粗体显示标签。

我错过了什么吗？谢谢

您正在使用HTMLWorker，一个不再受支持的过时类。它不支持 CSS 文件，这就解释了为什么所有关于 iText、HTML 和 CSS 的问题都没有得到解答。您应该使用XML Worker而不是HTMLWorker类。请参阅http://sourceforge.net/projects/itextsharp/files/xmlworker和http://demo.itextsupport.com/xmlworker

请尝试以下代码。我已经测试过，它应用了所有样式：

class Program
{
    private static void createPDF(string html)
    {
        FileStream fs = new FileStream("test.pdf", FileMode.Create);
        TextReader reader = new StringReader(html);

        Document document = new Document(PageSize.A4, 30, 30, 30, 30);

        PdfWriter writer = PdfWriter.GetInstance(document, fs);

        HTMLWorker worker = new HTMLWorker(document);

        document.Open();
        worker.StartDocument();

        worker.Parse(reader);

        worker.EndDocument();
        worker.Close();
        document.Close();

        fs.Close();
    }

    static void Main(string[] args)
    {
        string data = @"<table cellspacing='0' border='0' style='border-collapse:collapse;margin-top:30px;color:red;'>
                        <tr>
                            <td></td><td>Visit</td><td></td><td></td><td></td>
                    </tr><tr>
                            <th>Datw</th><td>07/01/2013</td><td>07/18/2013</td><td>07/17/2013</td><td>07/09/2013</td>
                    </tr><tr>
                            <th>Score</th><td>3.00</td><td>6.33</td><td>1.00</td><td>8.00</td>
                    </tr><tr>
                            <th>Heading</th><td>7.0</td><td>8.0</td><td>2.0</td><td>3.0</td>
                    </tr><tr>
                            <th>Minutes</th><td>88</td><td>n/a</td><td>22</td><td>n/a</td>
                    </tr><tr>
                            <th>Test Data</th><td>5.0</td><td>8.0</td><td>4.0</td><td>3.0</td>
                    </tr><tr>
                            <th>Status</th><td>8.0</td><td>8.0</td><td>3.0</td><td>3.0</td>
                    </tr><tr>
                            <th>Data </th><td>3.96</td><td>6.88</td><td>5.83</td><td>6.67</td>
                    </tr><tr>
                            <th>Assessment (0-10)</th><td>5.0</td><td>3.0</td><td>2.0</td><td>2.0</td>
                    </tr><tr>
                            <th class='seperator'>With heading</th><td>n/a</td><td>n/a</td><td>n/a</td><td>n/a</td>
                    </tr>
                </table>";

        createPDF(data);

        Console.ReadKey();
    }
}
