how to remove all non-digit characters from a string

Hello,

Is there a way to remove all non-digit characters from a string in one call?
string.Replace() methods don't allow this.

thanks!

string s = Regex.Replace(oBox.Text,"\\D","")

or "\\d" one means digit the other one means non digit. i forget at the
moment which is which.

Acutally, it should be Regex.Replace(myInput, @"\d", string.Empty);

Yeah, I flip back and forth between C# and VB.NET a lot, so I always code
like the other one for the first few hours. Someday I'll remember it @.
