Here's a simple example how you can detect URLs in some text and replace them with html code for hyperlinks:

string someText = "here's a simple text that contains urls in it like http://www.aspnetsource.com or http://aspnetsource.com or http://aspnetsource.com";

// we create a Regex object with pattern to detect URLs
Regex reg = new Regex(@"((http|https|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))*[\w\d:#@%/;$()~_?\+-=\\\.&]*)");

string htmText = reg.Replace(someText, "<a href=\"$1\">$1</a>");

/* now htmlText contains formatted html code with hrefs:

here's a simple text that contains urls in it like <a href="http://www.aspnetsource.com">http://www.aspnetsource.com</a> or <a href="http://aspnetsource.com">http://aspnetsource.com</a> or <a href="http://aspnetsource.com">http://aspnetsource.com</a>
