How do I recognize space characters in keyboard input? -- c#

I would like to recognize whitespace or nonascii characters in keyboard input. Is there an easy way to do this test? I
could do

e.KeyChar < '!' || e.KeyChar > '~'

but this seems to make the assumption that the user is inputting ascii characters - but maybe they are using some other
character set.

Can I use \s or is this for regular expression use only.

sorry it is such a basic question.

Thanks,

Steve

Hi,

Have you tried the static Char.IsXXX set of functions (Char.IsWhitespace ,
Char.IsLetter, etc.) They take a char as input and handle Unicode as well.

They may provide the functionality you are looking for.

\s only works as part of regular expressions.

Best regards,

Rodger
