How to use standard PDF fonts in C#

Register the font, then write text with it

Standard fonts are registered at the document level and then passed into the text-writing overload.

using ZingPDF;
using ZingPDF.Fonts;
using ZingPDF.Graphics;
using ZingPDF.Syntax.CommonDataStructures;

using var pdf = Pdf.Create();
var page = await pdf.GetPageAsync(1);
var font = await pdf.RegisterStandardFontAsync(StandardPdfFonts.HelveticaBold);

await page.AddTextAsync(
    "Quarterly report",
    Rectangle.FromDimensions(240, 80),
    font,
    18,
    RGBColour.Black);

await pdf.SaveAsync(File.Create("standard-font.pdf"));

Use the built-in font name helpers

ZingPDF exposes the standard font names through StandardPdfFonts, so you can choose from the common Helvetica, Times, and Courier variants without hard-coding the strings yourself.

That keeps the write path readable and makes it obvious which face the page content is using.

Use standard fonts when built-in PDF faces are enough

Standard fonts work well for labels, headers, simple reports, and generated output where Helvetica, Times, or Courier are acceptable.

If you need a specific corporate font or a font file you control, switch to embedded TrueType registration instead.
