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

Answer 1

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.

Answer 2

Have you tried:

currentBalance.ToString("#,##0.00");

This is the long-hand equivalent of:

currentBalance.ToString("N2");

Answer 3

You can do this with the group separator and the section separator, like this:

currentBalance.ToString("#,0.00;(#,0.00)");

This does not account for culture variances like the answer from @JonSkeet would, but this does mimic decimal place, rounding, thousands separation, and negative number handling that en-US culture currency format produces using a single custom format string.

Answer 4

var result = currentBalance.ToString("C").Replace(System.Globalization.CultureInfo.CurrentCulture.NumberFormat.CurrencySymbol, "");

Answer 5

This simple solution works for me with US currency.

If not needing international currency support use this and replace the $ with the currency symbol(s) to be removed:

// for USD
string result = currentBalance.ToString("C").Replace("$", "")

or

// for EUR
string result = currentBalance.ToString("C").Replace("€", "")

Answer 6

This may be overkill, but it rounds, formats...

@helper TwoDecimalPlaces(decimal? val)
{
    decimal x = 0;
    decimal y = 0;
    string clas = "text-danger";
    if (val.HasValue)
    {
        x = (decimal)val;
        if (val > 0)
        {
            clas = "";
        }
    }
    y = System.Math.Round(x, 2);
    IFormatProvider formatProvider = new System.Globalization.CultureInfo(string.Empty);
    <span class="@clas">@string.Format("{0:N2}", y)</span>
}
