   destinationFileName 
)

public:
void Convert( 
   int firstPageNumber,
   int lastPageNumber,
   String^ destinationFileName
)

Parameters

firstPageNumber: The 1-based number of the first page to be converted. Must be a value greater than or equal to 1.
lastPageNumber: The 1-based number of the last page to be converted. 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 (Nothing in Visual Basic) then the file name 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) constructurs or set the file name and optional password directly into the FileName and Password properties. You do not need to call Load before using this method.

This method can be used to work on all or portion of the pages in a PDF file. To use all the pages of a document, pass 1 and -1 for firstPageNumber and lastPageNumber.

This method will use the following properties of this PDFFile object:

DocumentProperties. If the value of this property is null (Nothing in Visual Basic), then default properties will be used
SecurityOptions. If the value of this property is not null (Nothing in Visual Basic), then the destination file will be encrypted using the properties of this property. If the value of this property is null (Nothing in Visual Basic), the result file will not be encrypted
CompatibilityLevel. The version of the generated PDF file
