Question

I have an ASP.net MVC website which is displaying numbers. Can I somehow determine if the user’s computer is configured to use a comma or a point as a decimal separator?

I could check the different languages in Request.UserLanguages but that would not be very accurate for determining the decimal separator.

Answer 1

You can see here how to get a CultureInfo from the browser language – this will get you
a CultureInfo object that you can use like this:

var sep = browserCulture.NumberFormat.NumberDecimalSeparator;

See CultureInfo and NumberFormatInfo.
