Question

I would like my WPF application to display all percentages without % sign. For example 20% would be displayed as “20” but i still want to use the standard formatting for percentages (so i get the benefit of string formatter to multiply it by 100 for me)

in other words, how do i get
string.Format("0.00%", 0.2) to output “20” but not “20%”?

Is it possible to globally define PercentSymbol as empty string for the entire application?

In particular i am using ContentStringFormat in my WPF application to format the numbers and percentages. Maybe i can do it directly in WPF.

Provide your own NumberFormatInfo to String.Format. Example based on the invariant culture:

NumberFormatInfo info = (NumberFormatInfo) CultureInfo.CurrentCulture.NumberFormat.Clone();
info.PercentSymbol = String.Empty;
string s = String.Format(info, "{0:00%}", 0.02);
