还是让我知道如何传递多个参数throgh pdftable.Addcell（）函数.. !!

Or let me know how to pass more than one parameters throgh pdftable.Addcell() function..!!

推荐答案

您要添加的图片对象直接到 PdfPCell 是这样的：

You are adding the Image object directly to a PdfPCell like this:

iTextSharp.text.Image image128 = code128.CreateImageWithBarcode(cb, null, null);
BarCodeTable.AddCell(image128);

第二行是短切的东西，看起来像这样：

The second line is a short cut for something that looks like this:

PdfPCell cell = new PdfPCell();
cell.SetImage(image128);
BarCodeTable.AddCEll(cell);

这细胞包含比的图像而已。有没有空间的文本

This cell contains nothing more than an image. There is no room for text.

如果您想将图片和文字结合起来，你需要的东西是这样的：

If you want to combine an image and text, you need something like this:

PdfPCell cell = new PdfPCell();
cell.AddElement(image128);
Paragraph p = new Paragraph("Student name");
p.Alignment = Element.ALIGN_CENTER;
cell.AddElement(p);
BarCodeTable.AddCEll(cell);
