How do I remove link annotations from a PDF using iText?

问题

Here i want to remove Annotation(Link, Text, ..) from PDF permanently using iTextSharp.

Already i have tried

AnnotationDictionary.Remove(PdfName.LINK);

But that Link annotations exist in that PDF.

Note:

I want remove particular selected Annotations(Link, Text, ..), For Example i want remove Link Annotation with the URI as www.google.com, remaining Link Annotations i want to be retain as per exist.

I got the answer for my question.

Sample Code:

//Get the current page
PageDictionary = R.GetPageN(i);

//Get all of the annotations for the current page
Annots = PageDictionary.GetAsArray(PdfName.ANNOTS);

foreach (PdfObject A in Annots.ArrayList)
{
//code to check the annotation 

//remove the annotation
Annots.Remove(int idx);

}
