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 https://docs.microsoft.com/en-us/dotnet/api/system.char.isletter?view=netframework-4.8 https://docs.microsoft.com/en-us/dotnet/api/system.char.isnumber?view=netframework-4.8 https://www.geeksforgeeks.org/c-sharp-char-isdigit-method/

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