Welcome to the forum.

Can't we use FileStream method for that. I said that based on Java, not at best in C#. Hope it will work.

There is a PDFParser class as well. May be it will help you. I found it on MSDN.

The first four charaters of a valid pdf file will should be:

%PDF-

using Acrobat;
using AFORMAUTLib;
private void DisplayPDFPageNumber(string FilePath)
{
AcroPDDocClass objPages = new AcroPDDocClass();
objPages.Open(FilePath);
long TotalPDFPages = objPages.GetNumPages();
objPages.Close();
AcroAVDocClass avDoc = new AcroAVDocClass();
avDoc.Open(FilePath, "Title");
IAFormApp formApp = new AFormAppClass();
IFields myFields = (IFields)formApp.Fields;
firstPageNumber = myFields.ExecuteThisJavascript("event.value=this.getPageLabel(0);");
long lst = TotalPDFPages - 1;
lastPageNumber = myFields.ExecuteThisJavascript("event.value=this.getPageLabel('" + lst + "');");
avDoc.Close(0);
}


This code is used to get the pdf page number.
You can get the first page number and the last page number.
