Format not getting applied in French culture

Question

I need to apply the format to the number of type decimal. Say a number 12345 must be shown in the format ## ##0,0. Then, the required output is 12 345,0.But somehow it does not apply correctly and I get the result as 1 2,345.

Below is the code that does the formatting work. Also check this fiddle where my issue is reproduced.

UPDATED

CultureInfo ci = new CultureInfo("fr-FR");
decimal integral = Convert.ToDecimal("12345");
Console.WriteLine(integral.ToString("## ##0,0"));

I know there are many format relevant solutions already available but unable to get what's wrong with this way.

Answer 1

You are not using the created culture information to format the number. Also, your format specifier is incorrect. You must always use the POINT as decimal separator in the format string, which is then replaced by the culture-specific decimal separator (a comma for fr-FR).

The following should work correctly:

integral.ToString("## ##0.0", ci)

Answer 2

you can use this function :

public static string FormatNumber(this double number)
        {
            return number.ToString("#,##0.00");
        }

And then call your function like :

decimal integral = Convert.ToDecimal("12345");
Console.WriteLine(integral.FormatNumber());
