void ExtractPages(

firstPageNumber
The 1-based number of the first page to be extracted. Must be a value greater than or equal to 1.
lastPageNumber
The 1-based number of the last page to be extracted. Must be a value greater than or equal to firstPageNumber and less than or equal to the total number of pages in the file. Use the special value of -1 to represents "last page in the file".
destinationFileName
Name of the destination PDF file to be created. If the value of this parameter is null then the filename set in FileName will be updated.
To use this method, associate this PDFFile object with a valid PDF file and optional password. You can achieve this by either using the PDFFile(string fileName) or PDFFile(string fileName, string password) constructors or set the filename and optional password directly into the FileName and Password properties. You do not need to call Load before using this method.
This method will use the following properties of this PDFFile object:
DocumentProperties. If the value of this property is null, then default properties will be used
SecurityOptions. If the value of this property is not null, then the destination file will be encrypted using the properties of this property. If the value of this property is null, the result file will not be encrypted
CompatibilityLevel. The version of the generated PDF file
This example will extract the pages a multipage PDF file.
