public class PDFExporter

    public void ExportToPDFWithRepeatedTitle(string[] titles, string outputPath)
    {
        // 创建PDF文档对象
        Document document = new Document();

        try
        {
            // 创建PDF写入器
            PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(outputPath, FileMode.Create));

            // 打开PDF文档
            document.Open();

            // 添加内容和重复标题
            foreach (string title in titles)
            {
                // 添加标题
                Paragraph titleParagraph = new Paragraph(title, new Font(Font.FontFamily.HELVETICA, 18, Font.BOLD));
                document.Add(titleParagraph);

                // 添加内容
                // ...

                // 添加分页符
                document.NewPage();
            }
        }
        catch (Exception ex)
        {
            // 处理异常
            Console.WriteLine("导出PDF时发生错误：" + ex.Message);
        }
        finally
        {
            // 关闭PDF文档
            document.Close();
        }
