C# code to linkify urls in a string

Question

Does anyone have any good c# code (and regular expressions) that will parse a string and \"linkify\" any urls that may be in the string?

Answer 1

This works for me:

str = Regex.Replace(str,
                @"((http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?)",
                "<a target='_blank' href='$1'>$1</a>");
