如何使用iTextSharp(在生成PDF文件时)连接不同的块并将它们添加到段落、段落和单元格,然后将单元格添加到表中

我能够在生成PDF文件时找到某个“位置”,因此看起来是这样的(页面的右侧应该是空白的):

这是我使用的代码:

using (var ms = new MemoryStream())
{
    using (var doc = new Document(PageSize.A4, 50, 50, 25, 25))
    {
        //Create a writer that's bound to our PDF abstraction and our stream
        using (var writer = PdfWriter.GetInstance(doc, ms))
        {

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

            var courierBold11Font = FontFactory.GetFont(FontFactory.COURIER_BOLD, 11, BaseColor.BLACK);
            var docTitle = new Paragraph("Mark Twain", courierBold11Font);
            doc.Add(docTitle);

            var timesRoman9Font = FontFactory.GetFont("Times Roman", 9, BaseColor.BLACK);
            var subTitle = new Paragraph("Roughing It", timesRoman9Font);
            doc.Add(subTitle);

            var courier9RedFont = FontFactory.GetFont("Courier", 9, BaseColor.RED);
            var importantNotice = new Paragraph("'All down but nine; set 'em up on the other alley, pard' - Scotty Briggs", courier9RedFont);
            importantNotice.Leading = 0;
            importantNotice.MultipliedLeading = 0.9F; // reduce the width between lines in the paragraph with these two settings

            PdfPTable table = new PdfPTable(1);
            PdfPCell cellImportantNote = new PdfPCell(importantNotice);
            cellImportantNote.BorderWidth = PdfPCell.NO_BORDER;
            table.WidthPercentage = 50;
            table.HorizontalAlignment = Element.ALIGN_LEFT;
            table.AddCell(cellImportantNote);
            doc.Add(table);

            doc.Close();
        }
        var bytes = ms.ToArray();
        String PDFTestOutputFileName = String.Format("iTextSharp_{0}.pdf", DateTime.Now.ToShortTimeString());
        PDFTestOutputFileName = PDFTestOutputFileName.Replace(":", "_");
        var testFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), PDFTestOutputFileName);
        File.WriteAllBytes(testFile, bytes);
        MessageBox.Show(String.Format("{0} written", PDFTestOutputFileName));
    }
}
但是,我需要分解红色文本,使其部分为粗体,部分为锚定标记/href,等等

我想我可以这样做:

var courier9RedBoldFont = FontFactory.GetFont(FontFactory.COURIER_BOLD, 9, BaseColor.RED);
// Build up chunkified version of "important notice"
Chunk boldpart = new Chunk("All down but nine - set 'em up on the other alley, pard", courier9RedBoldFont);
Chunk attribution = new Chunk("Scotty Briggs", courier9RedFont);

PdfPTable tbl = new PdfPTable(1);
tbl.WidthPercentage = 50;
tbl.HorizontalAlignment = Element.ALIGN_LEFT;
var par = new Paragraph();
par.Chunks.Add(boldpart);
par.Chunks.Add(attribution );
PdfPCell chunky = new PdfPCell(par);
chunky.BorderWidth = PdfPCell.NO_BORDER;
tbl.AddCell(chunky);                          
doc.Add(tbl);

…但这并不是在PDF文件中添加任何内容,但为什么不呢?单元格不包含段落吗?段落不能由块组成吗?

而不是
para.Chunks.Add()
只需使用
par.Add()
段落
返回的
块实际上来自基类
短语
。如果对于该属性,您将看到返回的集合实际上是动态创建的临时集合,因此它实际上是只读的
