我写的正则表达式来验证URL可能是要么喜欢

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

我已经用

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

它适用于HTTP和放大器; https.It是不工作的谷歌/ COM和放大器。 www.google.com。

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

请帮我解决这个问题。

感谢

推荐答案

无需使用正则表达式恕我直言 - 尝试

no need for a regex IMHO - try

Uri.IsWellFormedUriString(YourURLString, UriKind.RelativeOrAbsolute)
