How to detect culture requiring right-to-left text?

JohnHardman

When coding for Xamarin.Forms, how can I detect that the culture requires right-to-left text? I was expecting to be able to test CultureInfo.TextInfo.IsRightToLeft but that property does not seem to be available.

Answered my own question - it seems that IsRightToLeft is, like some of the other globalization stuff, (unexpectedly) private.

As a result, I ended up using reflection, as follows:

        bool rightToLeft = false;
        PropertyInfo propertyInfo = thisCulture.TextInfo.GetType().GetRuntimeProperty("IsRightToLeft");
        object value = propertyInfo?.GetValue(thisCulture.TextInfo);
        if (value is bool)
            rightToLeft = (bool) value;
