public Code11BarcodeCheckDigitType Code11CheckDigitType { get; set; }
A Code11BarcodeCheckDigitType enumeration member that indicates the check digit type to use when writing Code 11 barcodes. The default value is Code11BarcodeCheckDigitType.CDigit.
This property is only valid when writing Code 11 (USD-8) barcodes (BarcodeSymbology.Code11).
