Question

I need to determine the number of pages in a specified PDF file using C# code (.NET 2.0). The PDF file will be read from the file system, and not from an URL. Does anyone have any idea on how this could be done? Note: Adobe Acrobat Reader is installed on the PC where this check will be carried out.

Answer 1

You’ll need a PDF API for C#. iTextSharp is one possible API, though better ones might exist.

iTextSharp Example

You must install iTextSharp.dll as a reference. Download iTextsharp from SourceForge.net This is a complete working program using a console application.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using iTextSharp.text.pdf; using iTextSharp.text.xml; namespace GetPages_PDF {   class Program {     static void Main(string[] args)       {        // Right side of equation is location of YOUR pdf file         string ppath = 'C:\\aworking\\Hawkins.pdf';         PdfReader pdfReader = new PdfReader(ppath);         int numberOfPages = pdfReader.NumberOfPages;         Console.WriteLine(numberOfPages);         Console.ReadLine();       }    } }
