Use System.IO to determine file date to display 'new' image

This code tip reads in a directory of files, determines if the file date not older than 180 days and displays various image's. This builds a string and passes it to a Literal control.

<!%@ Import Namespace="system.IO" %>
<!%@ Register TagPrefix="Top" TagName="TopStuff" Src="toppage.ascx" %>
<!%@ Register TagPrefix="Bottom" TagName="BottomStuff" Src="bottompage.ascx" %>
<!script language="vb" runat="server">

Sub Page_Load(Sender as Object, E as EventArgs)

Dim count As Integer = files.Length
Dim i As Integer
dim daFiles as string
For i = 0 To count - 1
Dim theDate As Integer = DateDiff(DateInterval.Day, files(i).CreationTime, Date.Today)
If theDate < 180 Then
daFiles = daFiles & "<li><img src=new.gif'><a href='" & files(i).Name & "'>" & files(i).Name & "</a></li>"
Else
daFiles = daFiles & "<li><a href='" & files(i).Name & "'>" & files(i).Name & "</a></li>"
End If
Next

jokes.Text = "</ul>" & daFiles
End Sub
</script>
