How to get the page of the OCR'ed text?

string resulttext = string.Empty;
string out_filename = @"..\..\Data\result.txt";
//Load the existing PDF document.
PdfLoadedDocument lDoc = new PdfLoadedDocument(@"..\..\Data\Region.pdf");
for (int i = 0; i < lDoc.Pages.Count; i++)
{
// Initialize the OCR processor
using (OCRProcessor processor = new OCRProcessor(@"..\..\Tesseract binaries\"))
{
//Set the performance.
processor.Settings.Performance = Performance.Slow;
resulttext += " \n" + "page no " + i.ToString() + "\n";
//Process OCR by providing loaded PDF document page by page.
resulttext += processor.PerformOCR(lDoc, i, i, @"..\..\Tessdata\");
}
}
//save the OCRed text with page number
File.WriteAllText(out_filename, resulttext);
//close the document
lDoc.Close(true);
