C# iTextSharp multi fonts in a single cell

问题

First off I'm not that great with C# and it's been a while since I've worked with it..

I'm making a windows form for a friend that delivers packages. So I want to transfer his current paper form, into a .pdf with the library iTextSharp. He still needs to print the form to get the customer signature and so on.

What I need: I want the table to have a little headline, "Company name" for example, the text should be a little smaller than the text input from the windows form(richTextBox1)

Currently I'm using cells and was wondering if I can use 2 different font sizes within the same cell?

What I have:

table.AddCell("Static headline" + Chunk.NEWLINE + richTextBox1.Text);

What I "want":

var normalFont = FontFactory.GetFont(FontFactory.HELVETICA, 9);

var boldFont = FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 12);

table.AddCell("Static headline", boldFont + Chunk.NEWLINE + richTextBox1.Text, normalFont);

You're passing a String and a Font to the AddCell() method. That's not going to work. You need the AddCell() method that takes a Phrase object or a PdfPCell object as parameter.

A Phrase is an object that consists of different Chunks, and the different Chunks can have different font sizes. Please read chapter 2 of my book for more info about this object.

Phrase phrase = new Phrase();
phrase.Add(
    new Chunk("Some BOLD text",  new Font(Font.FontFamily.TIMES_ROMAN, 12, Font.BOLD))
);
phrase.Add(new Chunk(", some normal text", new Font()));
table.AddCell(phrase);

A PdfPCell is an object to which you can add different objects, such as Phrases, Paragraphs, Images,...

PdfPCell cell = new PdfPCell();
cell.AddElement(new Paragraph("Hello"));
cell.AddElement(list);
cell.AddElement(image);

In this snippet list is of type List and image is of type Image.

The first snippet uses text mode; the second snippet uses composite mode. Cells behave very differently depending on the mode you use.

This is all explained in the documentation; you can find hundreds of C# examples here.
