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.
