Best way to display decimal without trailing zeroes

Question

Is there a display formatter that will output decimals as these string representations in c# without doing any rounding?

// decimal -> string

20 -> 20         


        

Answer 1

Another solution, based on dyslexicanaboko's answer, but independent of the current culture:

public static string ToTrimmedString(this decimal num)
{
    string str = num.ToString();
    string decimalSeparator = CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator;
    if (str.Contains(decimalSeparator))
    {
        str = str.TrimEnd('0');
        if(str.EndsWith(decimalSeparator))
        {
            str = str.RemoveFromEnd(1);
        }
    }
    return str;
}

public static string RemoveFromEnd(this string str, int characterCount)
{
    return str.Remove(str.Length - characterCount, characterCount);
}
