string replacing - C#

Question

Say I have a string containing numbers and other chars.

I want to reduce the string to numbers only.

F.e. from 23232-2222-d23231 to 23232222223231

Can this be done with string.replace()?

if not, what's the simplest and shortest way?

10x!

Answer 1

There are a bunch of possibilities, from Regular Expressions to handling the text yourself. I'd go for this:

Regex.Replace(input, @"\D+", "")
