String parsing, extracting numbers and letters

Question

What\'s the easiest way to parse a string and extract a number and a letter? I have string that can be in the following format (number|letter or letter|number), i.e \"10A\",

Answer 1

Just to be different:

string number = input.Trim("ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray());
string letter = input.Trim("0123456789".ToCharArray());
