With " target"_blank">PDF .Net, you can get, create, remove or reorder PDF document pages in your C# or VB.NET application.
The pages of a PDF document are accessed through a structure known as the page tree, which defines the ordering of pages in the document. The tree structure allows PDF consumer applications, using only limited memory, to quickly open a PDF document containing thousands of pages. For more information, see Document Structure help page.
The following example shows how you can create a page tree structure from scratch.
