Question

I have a string of the form:

codename123

Is there a regular expression that can be used with Regex.Split() to split the alphabetic part and the numeric part into a two-element string array?

Answer 1

I know you asked for the Split method, but as an alternative you could use named capturing groups:

var numAlpha = new Regex("(?<Alpha>[a-zA-Z]*)(?<Numeric>[0-9]*)");
var match = numAlpha.Match("codename123");

var alpha = match.Groups["Alpha"].Value;
var num = match.Groups["Numeric"].Value;
