Question

I have a string containg alphabetic characters, for example:

1. 254.69 meters
2. 26.56 cm
3. 23.36 inches
4. 100.85 ft

I want to remove all the alphabetic characters (units) from the above mentioned strings so that I can call the double.Parse() method.

Answer 1

This should work:

// add directive at the top 
using System.Text.RegularExpressions;

string numberOnly = Regex.Replace(s, "[^0-9.]", "")
