Remove alphabets from a string
<p>I want to remove alphabets from a string. What is the best way to do it. To be more precise, i have MAC address of a system, and I want to extract only the numbers from it. I have found this article or stackoverflow. <a href="http://stackoverflow.com/questions/2645960/how-to-split-string-into-numerics-and-alphabets-using-regex">link text</a></p>

<p>I want to know, if using the regex is the best way or there are other ways to do it (maybe using LINQ).</p>
