remove alpha characters and white space from string

.net, c#

Solution

You can use \s.

For example:

presaleEstimateHigh = Regex.Replace(presaleEstimateHigh, @"[A-Za-z\s]", string.Empty);

Problem

I have a string which contains many characters. I want to remove A-Za-z and white space and be left with the rest. What's the best way to do this? Here's what I've tried ``` presaleEstimateHigh = Regex.Replace(presaleEstimateHigh, @"[A-Za-z]", string.Empty); ``` but I also need to remove white space.
