Regular Expression Problem
Hi,
I'm trying to get a regular expression to validate user input. The expression should prevent the use of empty string's or non-digit's. At the moment I'm using Regex,IsMatch(input, @"(^)|(\D)") but this does not work. On their own they appear to work fine, but I would like to combine them into one check. Is this possible? Mark

Code:
IsMatch(input, @"(\D)") You don't need to check if nothing is there, it'll fail if it doesn't match a digit i.e it's blank. If it doesn't work let me know.
