string outputPath = Path.Combine("Your Document Directory", "result" + Path.GetExtension("input.pdf"));

Step 2: Load Annotated Document

Load the document that contains annotations with replies using the Annotator class:

using (Annotator annotator = new Annotator("annotated_with_replies.pdf"))

Step 3: Obtain Annotations

Retrieve the annotations collection from the loaded document:

List<AnnotationBase> annotations = annotator.Get();

Step 4: Remove Replies

Remove all replies where the author’s name matches the specified user name. In this example, replies authored by “Tom” will be removed:

annotations[0].Replies.RemoveAll(x => x.User.Name == "Tom");

Step 5: Save Changes

Save the updated annotations back to the document and specify the output path:

annotator.Update(annotations);
annotator.Save(outputPath);

Step 6: Display Confirmation

Finally, inform the user that the document has been saved successfully and provide the path to the output file:

Console.WriteLine($"\nDocument saved successfully.\nCheck output in {outputPath}.");
