Replacing few different characters in a string

I try to replace few characters in some string 14/04/2010 17:12:11 and get, for example, next result:

14%04%2010%17%12%11

I know about method Replace, but its definition looks like Replace(Char,Char). Which means using it 3 times in method chain. Doesn't look idiomatic. How to solve the problem in an optimal way? Regular expressions? Any ways to escape them?

Regex.Replace(myString, "[/ :]", "%");

Simple, yet elegant!

An alternate Regex approach, although I disagree with the use of it here. This simply replaces any non-numeric characters:

string date2 = Regex.Replace(date1, @"\D", "%");

If you have to do it often, write a method:

static string Replace(string s, string c, char n)
{            
    for (int i = 0; i < c.Length; i++)
        s = s.Replace(c[i], n);            
    return s;
}

e.g.

string s1 = "14/04/2010 17:12:11";                
string s2 = Replace(s1, "/ :", '%'));

Chain it:

string s1 = "14/04/2010 17:12:1";

string s2 = s1.Replace("/","%").Replace(" ","%").Replace(":","%");
