防止MigraDoc中的段落分裂

我使用 MigraDoc 从一些数据库表中生成c＃中的PDF文件 .

我的主要问题是我添加的一些段落，它们无法安装到当前页面中，因此分成下一页，如何防止它？我希望他们在一个页面（当前页面或下一页） .

Document doc = new Document();
        Section section = doc.AddSection();
        Paragraph paragraph = section.AddParagraph();
        paragraph.AddLineBreak();
        paragraph.AddLineBreak();
        paragraph.AddLineBreak();

        paragraph.Format.TabStops.ClearAll();
        paragraph.Format.TabStops.AddTabStop("16cm", TabAlignment.Right, TabLeader.Lines);
        paragraph.AddTab();

        for (int i = 0; i < 20; i++)
        {

            Paragraph paragraphBody = paragraph.Section.AddParagraph();

            FormattedText ft = paragraphBody.AddFormattedText("This is a title", TextFormat.Bold);
            ft.Italic = true; ft.Font.Size = 11;
            ft.Font.Color = Color.FromRgbColor((byte)255, Color.Parse("0x1E9BC6")); //equal to rgb(30, 155, 196);
            ft.AddLineBreak();

            //--detail:---adding text---------------------------------

            String DetailText = "This is detail. This is detail. This is detail.This is detail.This is detail.This is detail.This is detail.This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. This is detail. ";

            FormattedText ftdet;
            ftdet = paragraphBody.AddFormattedText(DetailText, TextFormat.NotBold);
            ftdet.Font.Size = 10;
            ftdet.Font.Name = "Arial";
            ftdet.AddLineBreak();
            ftdet.AddLineBreak();

            ftdet.AddText("Event Date: " + DateTime.Now.ToString("MM/dd/yyyy h:mm tt"));
        }

        PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer(false, PdfFontEmbedding.Always);
        pdfRenderer.Document = doc;
        pdfRenderer.RenderDocument();

        //Save the PDF to a file:
        string filename = "e:\\Report" +    DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".pdf";
pdfRenderer.PdfDocument.Save(filename);

        Process.Start(filename);
