Leadtools.Pdf Namespace > PDFFile Class : GetPageCount Method |
public int GetPageCount()
'Declaration Public Function GetPageCount() As Integer
public: int GetPageCount();
This method will obtain the number of pages in the PDF file set in FileName. Since obtaining the number of pages might require decrypting a secured file, the value of the password set in Password will be used if the file is encrypted.
To get the size of each page in a PDF file, use the Load method which populates the Pages collection with an PDFFilePage for each page.
This method is faster than calling Load and using Pages.Count since it does not parse the page sizes not load the document properties.
