How to determine currency symbol position for a culture

Question

I am trying to determine whether the currency symbol for a given culture should appear at the beginning or end of the value. I have not been able to find this bit of information in the .Net CultureInfo, so I thought I'd try a hack:

var cultures = new[] {"en-US", "ar-SA", "as-IN", "tr-TR"};
foreach ( var culture in cultures ) {
    var cultureInfo = CultureInfo.CreateSpecificCulture( culture );

    var currencyValue = 1.234.ToString( "C", cultureInfo );

    var rtl = cultureInfo.TextInfo.IsRightToLeft;

    var symbolAtBeginning = currencyValue.StartsWith( cultureInfo.NumberFormat.CurrencySymbol, false, cultureInfo );
}

Alas, this method works only sometimes; in the example above, it works for "en-US" but not the rest of the cultures. At first I thought it was because some cultures read text right-to-left, and the "start" would be the right side, but that explanation did not prove out.

Does anyone see the flaw in my code, or preferably, have a better method for determining the currency symbol position?

Answer 1

You can use the NumberFormatInfo class to determine that information. You can read the CurrencyPositive property for positive values and it will return an int repesenting the position. From MSDN:

0  $n

1  n$

2  $ n

3  n $
