That doesn't make a lot of sense as a question: PDF files and image files are very different beasties - and you can't do the same things with them. In particular, a PDF file doesn't have "rows" in the same way that an image file does: it's "row" is flexible depending on the output width and zoom level, where an image generally has a fixed width and height - allowing it to have rows and columns, even if the data may not be stored in that way.
Please, elaborate your question and try to explain in better detail what you are trying to do!

Such thing as "number of rows" is not applicable to image, and it is not even applicable to PDF. The question makes no sense. If you define something which you call "number of rows", we can discuss it, but I doubt you can do it.

Add iTextSharp.dll as a reference. Download from SourceForge.net
Let try this:

C#

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)
      {
        string pdfPath = "C:\\sources\\helloworld.pdf";
        PdfReader pdfReader = new PdfReader(pdfPath);
        int noOfPages = pdfReader.NumberOfPages;
        Console.WriteLine(noOfPages); 
      }
   }
}
