How to extract the numerical part of a monetary value?

Question

I have a string with the characters "R$ 1,000.60" and would like to extract only the characters "1,000.60".

I tried using regular expression, but I couldn’t reach my goal. I got to this:

    string valor = "";
    string texto = "R$ 1.000,60";

    Regex r = new Regex(@"^[0-9]*(?:\.[0-9]*)?$");
    foreach (Match m in r.Matches(texto))
        valor += m.Value;

Would anyone know how to solve this problem using regular expression or other technique?

Answer 1

Change to the following:

 var r = new Regex(@"[0-9]*(\.[0-9]{3})*(,[0-9]{2})?$");

Here is a functional example of regular expression.
