Tricks for handling number keys? (C#)

bgowland · 2005-11-14, 07:00 PM

In OnKeyDown(...), I want to simply identify if the the key is from 0-9, i.e., kind of an 'IsNumeric' type step. When I programmed with C years ago I'd have probably converted to ASCII then just checked if the value was between 0x30 and 0x39. Does C# offer anything cleverer than this?

Cheers,
Brian

I don't think it has a isNumeric. I remember looking for something similar. I think I ended up writing (ok I grabbed it from the web) a routine to do the same as isnumeric.

Basically you test each character
