Regular expressions are very commonly used by any developer no matter what language he's writing his program. Today I'll show the most useful Regex that sooner or later you will need them. For c# or vb.net. You want to check whether a certain string represents a valid IPv4 address in 255.255.255.255 notation. Optionally, you want to convert this address into a 32-bit integer.

If I apply the regex below over it:
(http|ftp)://([^/\r\n]+)(/[^\r\n]*)?
I would get the following result:
Match "http://stackoverflow.com/"
Group 1: "http"
Group 2: "stackoverflow.com"
Group 3: "/"
But I don't care about the protocol - I just want the host and path of the URL. So, I change the regex to include the non-capturing group (?:):
(?:http|ftp)://([^/\r\n]+)(/[^\r\n]*)?
Now, my result looks like this:
Match "http://stackoverflow.com/"
Group 1: "stackoverflow.com"
Group 2: "/"
