Replace all non-word characters with a space

Question

I have a regex

[A-Za-z]

and a string, such as

Hi! This is a string.

I want to replace all charcters that are not in the Regex with space. So, I'll end up with

Hi This is a string

How is this done?

Answer 1

var cleaned = Regex.Replace(given, "[^A-Za-z]", " ");
