[thelist] Parsing URLs in ASP.net

[Howard Cheng]

In ASP.NET you'll be using (assuming you're using VB.NET) something like
the following: (not tested!)

Imports System
Imports System.Text.RegularExpressions

Public Class MyClass

Private httpExpression As String =
"(http|ftp|https):\/\/[\w]+(.[\w]+)([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?"

Public Function MakeLink(sInput As String) As String

     Dim re As New Regex(httpExpression, Regex.IgnoreCase)
     Dim oMatch As Match
     Dim sOutput As String = ""

     If re.IsMatch(sInput) Then
         oMatch = re.Match(sInput)

         sOutput = "<a href=""" & oMatch.Result & """>" & oMatch.Result &
"</a>"
     End If

     Return sOutput

End Function

End Class

If you're really daring, you could also try using the UriBuilder class. (:
