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

Docotic Pdf library may be used to accomplish the task  Here is sample code  PdfDocument document   new PdfDocument    document Open  quot file pdf quot    int pageCount   document PageCount   The library will parse as little as possible so performance should be ok  Disclaimer  I work for Bit Miracle

I ve used the code above that solves the problem using regex and it works  but it s quite slow  It reads the entire file to determine the number of pages   I used it in a web app and pages would sometimes list 20 or 30 PDFs at a time and in that circumstance the load time for the page went from a couple seconds to almost a minute due to the page counting method   I don t know if the 3rd party libraries are much better  I would hope that they are and I ve used pdflib in other scenarios with success
