This class is used to define a single range of adjacent pages. For example, this object can represent all of the pages within the range 1 through 10. It can also represent a single page. To describe a series of non-contiguous pages (e.g. 1 - 10 and 15-18), simply create a PageRange for each contiguous range of pages, and add each PageRange object to a PageList collection object.

The PageList collection object is used by the InsertPagesOptions to define which pages will be inserted from the SourceDocument into the target document.
