The Char-type has lots of methods that will tell you if a particular char is a number or a character.
try
Char.IsNumber(your char)
Char.IsLetter(your char)
So loop through the user-input, get single chars and check with these functions

I think , easiest way it look ASCII table, get HEX codes for chars and numbers, and then write if-else comparator.
