Converting an integer to a string according to the current regional settings in an UWP application

Question

Hi,

I have the following example code in an UWP application:

int number = 1234;
string str = number.ToString("N0");

var cultureInfo = CultureInfo.CurrentCulture;

I have also selected German "de-DE" in my regional settings in Windows (default regional format).

However str is "1,234" in this example and cultureInfo is "en-US".

It should be "1.234" and "de-DE".

How can I fix this?

Thanks

Jus

Hello,

Here is a workaround that can get the correct CultureInfo.

1. Use GlobalizationPreferences.Languages to get current Language setting and convert it to CultureInfo.
2. Use Windows.Globalization.NumberFormatting.DecimalFormatter to convert the number to the correct format.

var cultureInfo= new System.Globalization.CultureInfo(Windows.System.UserProfile.GlobalizationPreferences.Languages[0]);
           
var valueToBeFormatted = 1234567891.23;

string currentLanguage= cultureInfo.Name;
string currentRegion = Windows.System.UserProfile.GlobalizationPreferences.HomeGeographicRegion;

// In this case it's the Euro with the default number formatting for Germany.
var DecimalFormatEuroDE = new Windows.Globalization.NumberFormatting.DecimalFormatter(new[] { currentLanguage }, currentRegion);
DecimalFormatEuroDE.IsGrouped = true;
var DecimalValueEuroDE = DecimalFormatEuroDE.Format(valueToBeFormatted);

// Results for display.
var results = "Fixed number (" + valueToBeFormatted + ")\n" +
                "Formatted Euro (de-DE defaults): " + DecimalValueEuroDE;
Debug.WriteLine(results);

Thank you
