I've got an ASP.net file, and I'm trying to include dynamic code which was easy in classic ASP.

Here is what I have tried so far:

<%@ Register TagPrefix="TagPre" TagName="header" Src="alg/classes.aspx"%> 

and

<!--#include file="alg/classes.aspx"-->

But neither of these seem to work. The content of classes.aspx is:

<script runat="server">   
' Square class
Public Class square

    Public sqRows As Integer        'Numbers of rows this square has
    Public sqCols As Integer        'Number of columns this square has
    Public sqArray(,) As Integer    'The square array

    ' Initialise square array to match size of canvas
    Public Sub initSqArray(ByVal canvCols, ByVal canvRows)
        ReDim sqArray(canvCols, canvRows)
        sqRows = canvRows
        sqCols = canvCols
    End Sub

End Class

Thanks for any help!
