Determine Number of Pages in a PDF File using C# (.NET 2.0)

I used the following code to get the count of number of pdf files in a directory.

    var extensions = new HashSet<string>(StringComparer.OrdinalIgnoreCase) 
    {
        ".pdf", 
    };
    var baseDir = BatchFolderPath;
    var pdfFilesCount = Directory.EnumerateFiles(baseDir)
                                 .Count(filename =>
                                        extensions.Contains(Path.GetExtension(filename)));

I don’t know how to get the number of pages inside each pdf document inside a directory. Please help. Thanks.

Question like has been already asked Stack Overflow here.
Hope it helps.

EDIT:
This is how you can find the number of pages in each pdf file present in your specified directory:

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

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            int PgCount = 0;
            string[] PdfFiles = Directory.GetFiles(@"C:\MyFolder\", "*.pdf");
            Console.WriteLine("{0} PDF Files in directory", PdfFiles.Length.ToString());
            for (int i = 0; i < PdfFiles.Length; i++)
            {
                PgCount = GetNumberOfPages(PdfFiles[i]);
                Console.WriteLine("{0} File has {1} pages", PdfFiles[i], PgCount.ToString());
            }
            Console.ReadLine();
        }

        static int GetNumberOfPages(String FilePath)
        {
            PdfReader pdfReader = new PdfReader(FilePath); 
            return pdfReader.NumberOfPages; 
        }
    }
}  

You will have to download itextsharp.dll from here and include that in References.
