Hi, I want the user to be able to enter any form of number in my price textbox and I will automatically strip anything that is not an integer.

I obviously can't mand a string.replace for every character, so is there a way to use a regexp to say anything that isnt 0-9?

This will match any unsigned integer:   ^\d*$     So is there a way to say   if(! ^\d*$)?

Thanks, Dave

you could just say .ToCharArray() and then use if char >= '0' && char <= '9' to determine if its numeric ...

or you could just use Char.IsNumber()

Hi KaiserSose,

string result = Regex.Replace(input,"\\d",String.Empty)
