How do I format a C# decimal to remove extra following 0's?

Question

I want to format a string as a decimal, but the decimal contains some following zeros after the decimal. How do I format it such that those meaningless 0\'s disappear?

Answer 1

How about:

string FormatDecimal(decimal d)
{
    const char point = System.Globalization.NumberFormatInfo.CurrentInfo.NumberDecimalSeparator[0];
    string s = d.ToString();
    // if there's no decimal point, there's nothing to trim
    if (!s.Contains(point) == -1)
        return s;
    // trim any trailing 0s, followed by the decimal point if necessary
    return s.TrimEnd('0').TrimEnd(point);
}
