Format a decimal to a minor currency

Question

I need to format a decimal to a minor currency eg 10.00 should be 1000.

decimal currency = 10.00m;
System.Console.WriteLine(currency.ToString("######"));

Produces 10, how do I get the decimal points to be added to that?

Answer 1

解决方案非常简单

* 100

Answer 2

I would create an extension method like this that would produce always the expected result, with the required number of decimals:

public static class DecimalExtension
{
    public static string FormatAsMinorCurrency(this decimal value) {
        var numberFormat = (NumberFormatInfo)CultureInfo.CurrentCulture.NumberFormat.Clone();
        numberFormat.CurrencyDecimalDigits = 2;
        numberFormat.CurrencyDecimalSeparator = ".";
        numberFormat.CurrencySymbol = "";
        numberFormat.CurrencyGroupSeparator = "";
        return value.ToString("c", numberFormat).Replace(".", "");
    }
}

The results:

1.FormatAsMinorCurrency() 
100

10.FormatAsMinorCurrency()
1000

1000000.34102350915091M.FormatAsMinorCurrency()
100000034
