Question

I have written regex to validate URL which could be either like

google.com

www.google.com

http://www.google.com

https://www.google.com

I have used

Regex urlRx = new Regex(@"^(http|ftp|https|www)://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&\*\(\)_\-\=\+\\\/\?\.\:\;\'\,]*)?$", RegexOptions.IgnoreCase);

It works for http & https.It is not working for google./com & http://www.google.com.

Please help me to solve this.

Thanks

Answer 1

no need for a regex IMHO – try

Uri.IsWellFormedUriString(YourURLString, UriKind.RelativeOrAbsolute)

See MSDN
