Parameters

replacePageNumber: The 1-based number of the replacement point in this PDFFile object. Must be greater than or equal to 1 and less than or equal to the total number of pages in sourceFile.
sourceFile: A PDFFile object associated with an existing PDF file that contain the source file to replace the pages from.
firstPageNumber: The 1-based number of the first page in the source file to be replaced. Must be a value greater than or equal to 1.
lastPageNumber: The 1-based number of the last page in the source file to be replaced. 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 represent "last page in the file".

Both files in this PDFFile (the destination) and sourceFile must exist and contain valid PDF files prior to calling this method.

To use this method, associate this PDFFile object and the source PDFFile 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 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
