Yes, you do really have to change your code!

Depending on localization (country, regional settings) the decimal and/or thousand separator may differ. So, you have to use Decimal.TryParse(String, NumberStyles, IFormatProvider, Decimal)[^] method, which provides proper "convertion" using specific CultureInfo class[^].
