HOW TO: use the Document Writer's progress event?

int progressCounter = 0;
int progressPageNumber = 1;
docWriter.Progress += (sender, e) =>
{
   if(progressCounter == 0) //Begin Document
   {
      Console.Write("\rBegin Document: {0}%", e.Percentage);
   }
   else if(progressCounter <= NUMBER_DOCUMENT_PAGES)  //Processing page
   {
      Console.Write("\rProcessing Page #{0}: {1}%", progressPageNumber, e.Percentage);

      if (e.Percentage == 100)
         progressPageNumber++;
   }
   else if(progressCounter == (NUMBER_DOCUMENT_PAGES + 1)) //End document
   {
      Console.Write("\rFinalizing document - {0}%", e.Percentage);
   }

   if (e.Percentage == 100)
   { 
      progressCounter++;
      Console.WriteLine("");
   }

};
