Regex text (including period) and number C# : <p>I'm having a string which contains text (that may have periods in it) followed by a number, and I'm trying to separate text from the number, the code I'm using evaluates the string char by char but is taking too long, so I've tried to use regex but I can't include the period.</p>

<p>If the input is A.B123, y need an array or list like: ["A.B","123"]</p>
