I think you are a little confused.
I just tried it:

C#

Dictionary<string, object> d = new Dictionary<string, object>();
for (int ii = 1; ii < 10; ii++)
    d.Add((ii * 111).ToString(), ii * 11);
Console.WriteLine(d[d.Keys.ToArray()[0]]);
Console.WriteLine(d.Values.ToArray()[0]);
IList<Dictionary<string, object>> bookmarks = new List<Dictionary<string, object>>();
bookmarks.Add(d);
int i = 0;
Console.WriteLine(bookmarks[i].Values.ToArray().GetValue(0).ToString());

And it compiled and ran perfectly...

So what am I doing that is different from you?

Hi OriginalGrif

It showing same error In ToArray

"System.Collections.Generic.Dictionary<string,object>.ValueCollection' does not contain a definition for 'ToArray' and no extension method 'ToArray' accepting a first argument of type"

Ah! Have you been playing your your *using* statements?
Put this back in:
using System.Linq;
And I think it'll work...

PdfDictionary AnnotationDictionary = (PdfDictionary)PdfReader.GetPdfObject(A);

//Make sure this annotation has a link

if (!AnnotationDictionary.Get(PdfName.SUBTYPE).Equals(PdfName.LINK))
continue;

//Make sure this annotation has an ACTION
if (AnnotationDictionary.Get(PdfName.A) == null)
continue;

//Get the ACTION for the current annotation
PdfDictionary AnnotationAction = AnnotationDictionary.GetAsDict(PdfName.A);
// PdfDictionary AnnotationAction = (PdfDictionary)AnnotationDictionary.Get(PdfName.A);

if (AnnotationAction.Get(PdfName.S).Equals(PdfName.URI))

Sorry, but I can't - I don't use ITextSharp that much.
You will have to raise a new question!
