我从数据库中获取一些值并设置为带有标题的 itextsharp PdfPCell。这是我的一些代码。

    var a = _db.persons.SingleOrDefault(m => m.id == Person.Id);

    var table = new PdfPTable(2) {WidthPercentage = 100};
    table.DefaultCell.Border = Rectangle.NO_BORDER;
    var columns = new[] { 50f, 50f };
    table.SetWidths(columns);


    var bt1a = new PdfPCell(new Phrase("Name, surname:", fontGeneralText));
    var bt2a = new PdfPCell(new Phrase("Personal Id:", fontGeneralText));
    var bt3a = new PdfPCell(new Phrase("Phone number:", fontGeneralText));
    var bt4a = new PdfPCell(new Phrase("Department:", fontGeneralText));
    var bt5a = new PdfPCell(new Phrase("University:", fontGeneralText));
    var bt6a = new PdfPCell(new Phrase("Faculty:", fontGeneralText));

    var bt1b = new PdfPCell(new Phrase(a.name_surname, fontBoldText));
    var bt2b = new PdfPCell(new Phrase(a.personal_id, fontGeneralText));
    var bt3b = new PdfPCell(new Phrase(a.phne_number, fontGeneralText));
    var bt4b = new PdfPCell(new Phrase(a.department, fontGeneralText));
    var bt5b = new PdfPCell(new Phrase(a.university, fontGeneralText));
    var bt6b = new PdfPCell(new Phrase(a.faculty, fontGeneralText));

    table.AddCell(bt1a);
    table.AddCell(bt1b);

    table.AddCell(bt2a);
    table.AddCell(bt2b);

    table.AddCell(bt3a);
    table.AddCell(bt3b);

    table.AddCell(bt4a);
    table.AddCell(bt4b);

    table.AddCell(bt5a);
    table.AddCell(bt5b);

    table.AddCell(bt6a);
    table.AddCell(bt6b);

    doc.Add(table);

但它是非常业余的编码风格。因为我编写相同的结构并且只更改参数。有什么方法可以实现自动化方法，例如使用 foreach 等。

我认为它可以顺便完成，但我不知道在这里之后：

    List<string> titles = new List<string>() {"Name, surname:", "Personal Id:", "Phone number:", "Department:", "University:", "Faculty:"};

    List<Phrase> datas = new List<Phrase>() { new Phrase(a.name_surname, fontGeneralText), new Phrase(a.personal_id, fontGeneralText), new Phrase(a.phone_number, fontGeneralText), new Phrase(a.department, fontGeneralText), new Phrase(a.university, fontGeneralText), new Phrase(a.faculty, fontGeneralText)};


    foreach (var titles in title)
    {
        MessageBox.Show(title);
    }

从上面的代码示例中，您已经拥有titlesand datas。因此，只需创建这两个集合所需的正确字体 - 如下所示：

List<string> titles = new List<string>() 
{ 
    "Name, surname:", "Personal Id:", "Phone number:", 
    "Department:", "University:", "Faculty:" 
};
List<string> datas = new List<string>() 
{ 
    "0", "1", "2", "3", "4", "5"
};
Font timesBold = FontFactory.GetFont("Times-Roman", 8, Font.BOLD);
Font timesNormal = FontFactory.GetFont("Times-Roman", 8, Font.NORMAL);

然后将这些参数传递给与此类似的方法：

// you should also verify titles and datas have same 'Count'
public void FillTable(List<string> titles, List<string> datas, 
    Font titleFont, Font dataFont)
{
    var table = new PdfPTable(2) { WidthPercentage = 100 };
    table.DefaultCell.Border = Rectangle.NO_BORDER;
    var columns = new[] { 50f, 50f };
    table.SetWidths(columns);

    using (FileStream stream = new FileStream(
        OUT_FILE,
        FileMode.Create,
        FileAccess.Write))
    {
        using (var document = new Document())
        {
            PdfWriter.GetInstance(document, stream);
            document.Open();
            for (int i = 0; i < titles.Count; ++i)
            {
                table.AddCell(new PdfPCell(new Phrase(titles[i], titleFont)));
                table.AddCell(new PdfPCell(new Phrase(datas[i], dataFont)));
            }
            document.Add(table);
        }
    }
}
