How to check whether a string is a valid url

Question

I use this code to valid url

public static bool isUrl(string text) { Uri uriResult; return Uri.TryCreate(text, UriKind.Absolute, out uriResult) && uriResult.Scheme == Uri.UriSchemeHttp; }

but this code, not working when i send parameters like google.com, www.google.com

it only work when i use http like http://google.com

i need a code for c#, like Patterns.WEB_URL.matcher(text).matches(); in android

I use this regex.

[-a-zA-Z0-9@:%._\+~#=]{2,256}\.[a-z]{2,6}\b([-a-zA-Z0-9@:%_\+.~#?&\/=]*)

Here's the regex in action with this question's url:

So if a match is found you got yourself a URL. And if in the future you need to get parts of it it can do that for you too.
