There are several libraries available in C# that allow you to create PDF documents, such as iTextSharp, PdfSharp, and MigraDoc. One of the most popular libraries for creating PDFs in C# is iTextSharp. Here is an example of how to create a two-page PDF using iTextSharp:

using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;

Document document = new Document();
PdfWriter.GetInstance(document, new FileStream("two-page-pdf.pdf", FileMode.Create));
document.Open();

// Add first page
document.Add(new Paragraph("This is the first page"));
document.NewPage();

// Add second page
document.Add(new Paragraph("This is the second page"));
document.Close();
