Property Value

This property provides a snapshot of the list of keys in the PDF document. Any keys added after this property is accessed will not be available in the string array that was returned. Simply access this property again to get a new list which contains the added keys.

Since the array type implements IEnumerable, you can use foreach iteration on all arrays in C#, or the For Each iteration on all arrays in VB.NET.
