    // Get total number of pages
    int totalPages = new PdfFileInfo(_dataDir + "sample.pdf").NumberOfPages;

    // Create formatted text for page number
    FormattedText formattedText = new FormattedText($"Page # of {totalPages}",
        System.Drawing.Color.AntiqueWhite,
        System.Drawing.Color.Gray,
        FontStyle.TimesBoldItalic,
        EncodingType.Winansi, false, 12);

Specified below are values offered in this enumeration.

• LettersLowercase
• LettersUppercase
• NumeralsArabic
• NumeralsRomanLowercase
• NumeralsRomanUppercase

    // Create PdfFileStamp object
    PdfFileStamp fileStamp = new PdfFileStamp();

    // Open Document
    fileStamp.BindPdf(_dataDir + "sample.pdf");

    // Get total number of pages
    int totalPages = new PdfFileInfo(_dataDir + "sample.pdf").NumberOfPages;

    // Create formatted text for page number

        System.Drawing.Color.Gray,
        FontStyle.TimesBoldItalic,
        EncodingType.Winansi, false, 12);

    // Set starting number for first page; you might want to start from 2 or more
    fileStamp.StartingNumber = 1;
