class PDFDocumentPageCollection(ReadOnlyCollection):
The PDFDocumentPageCollection is used as the type for the PDFDocument.Pages property.
When a PDFDocument object is constructed from a PDF file, PDFDocument.Pages is automatically created and populated with a PDFDocumentPage object for each page found in the PDF file.
PDFDocument is a read-only view of a PDF file. As a result, the PDFDocumentPageCollection is created as a read-only collection to the pages.
