Regex for IP address

Question

I tried this code for validating IP address, but it doesn\'t work...

public static bool IP(string ipStr)
{
    string pattern = @\"^([1-9]|[1-9][0-9]|1[0-9][         


        

Answer 1

There is a previously answered question available for a valid IP address.

As for debugging regular expressions, on Windows I heartily recommend Expresso. On the web, there is a free Flash-based tester available.
