Format a double value like currency but without the currency sign (C#)

Question

I feed a textbox a string value showing me a balance that need to be formatted like this:

###,###,###,##0.00

I could use the value.ToString("c"), but this would put the currency sign in front of it.

Any idea how I would manipulate the string before feeding the textbox to achieve the above formatting?

I tried this, without success:

String.Format("###,###,###,##0.00", currentBalance);

Many Thanks,

If the currency formatting gives you exactly what you want, clone a NumberFormatInfo with and set the CurrencySymbol property to "". You should check that it handles negative numbers in the way that you want as well, of course.

For example:

using System;
using System.Globalization;

class Test
{
    static void Main()
    {
        NumberFormatInfo nfi = CultureInfo.CurrentCulture.NumberFormat;
        nfi = (NumberFormatInfo) nfi.Clone();

        Console.WriteLine(string.Format(nfi, "{0:c}", 123.45m));
        nfi.CurrencySymbol = "";
        Console.WriteLine(string.Format(nfi, "{0:c}", 123.45m));
    }
}

The other option is to use a custom numeric format string of course - it depends whether you really want to mirror exactly how a currency would look, just without the symbol, or control the exact positioning of digits.
