Q: I need PDF Library for our project. I found out that your library
is a very cool one and i downloaded trial version and tested it. When
i run AnnotationTest sample , i got the following error when i get the
following line.
if (action.GetType() == Action.Type.e_GoTo)
Exception: Message: Invalid Action
Please help me. I'd like to use your library. Yours is very simple to
use.

A:
It seems that you encountered an invalid action.
You can check is the annotation/action/destination is valid using
IsValid() method.
For example:
Annot annot = page.GetAnnot(i);
if (annot.IsValid() == false) continue;
if(annot.GetType() == Annot.Type.e_Link) {
Action action = annot.GetLinkAction();
if (action.GetType() == Action.Type.e_GoTo) {
Destination dest = action.GetDest();
if (dest.IsValid() == false) Console.WriteLine(" Not a valid
destination.");
else {
int page_num = dest.GetPage().GetIndex();
Console.WriteLine(" Links to: page number {0:d} in this
document", page_num);
}
}
}
