regex - Easiest way to convert a URL to a hyperlink in a C# string?

Question

I am consuming the Twitter API and want to convert all URLs to hyperlinks.

What is the most effective way you've come up with to do this?

from

string myString = "This is my tweet check it out http://tinyurl.com/blah";

to

This is my tweet check it out <a href="http://tinyurl.com/blah">http://tinyurl.com/>blah</a>

Answer 1

Regular expressions are probably your friend for this kind of task:

Regex r = new Regex(@"(https?://[^s]+)");
myString = r.Replace(myString, "<a href="$1">$1</a>");

The regular expression for matching URLs might need a bit of work.
