Getting this function to work in ASP.NET VB?

Hi guys,

I wrote this function in ASP to get the and display the modified date of a file.

<%
Function getLastModified()
    Dim strFile
    Dim File,oFile
    Dim dtmLMod
    Dim dtmLModDate

    strFile = Request.ServerVariables("SCRIPT_NAME")
    strFile = Replace(strFile, "/", "\")
    strFile = Server.MapPath(strFile)

    Set File = Server.CreateObject("Scripting.FileSystemObject")

    Set oFile = File.GetFile(strFile)
    dtmLMod = oFile.DateLastModified
    Set oFile = Nothing
    Set File = Nothing

    dtmLModDate = FormatDateTime(dtmLMod, 1)

    getLastModified = dtmLModDate
End Function
%>

I thought it might be .NET compatible, so I did the following:

<script language="VB" runat="server">    
Function getLastModified()
    Dim strFile
    Dim File,oFile
    Dim dtmLMod
    Dim dtmLModDate

    strFile = Request.ServerVariables("SCRIPT_NAME")
    strFile = Replace(strFile, "/", "\")
    strFile = Server.MapPath(strFile)

    Set File = Server.CreateObject("Scripting.FileSystemObject")

    Set oFile = File.GetFile(strFile)
    dtmLMod = oFile.DateLastModified
    Set oFile = Nothing
    Set File = Nothing

    dtmLModDate = FormatDateTime(dtmLMod, 1)

    getLastModified = dtmLModDate
End Function
</script>

However i'm getting the followin error message:

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: BC30807: 'Let' and 'Set' assignment statements are no longer supported.

Source Error:



Line 13:     strFile = Server.MapPath(strFile)
Line 14:
Line 15:     Set File = Server.CreateObject("Scripting.FileSystemObject")
Line 16:
Line 17:     Set oFile = File.GetFile(strFile)



Can anyone shed any light on what I need to change to make this script work in .net?

Thanks in advance
