reading text file in ASP

Do you know how to read each line of the file into a string variable? Once you have a line in the string, you can use the Mid() function to examine columns 256 & 257:

i have written the following code in ASP ..
how to convert it automatically in ASP.NET ?
i have tried changing the code but it is giving me erros .
code is:

<% Option Explicit

Const Filename = "/AGC-20070102-UPT.txt" ' file to read

Const ForReading = 1, ForWriting = 2, ForAppending = 3
Const TristateUseDefault = -2, TristateTrue = -1, TristateFalse = 0

' Create a filesystem object
Dim FSO
set FSO = server.createObject("Scripting.FileSystemObject")

' Map the logical path to the physical system path
Dim Filepath
Filepath = "//mu-bfs/manu/general/valProviderAddress/AGC-20070102-UPT.txt"

if FSO.FileExists(Filepath) Then

' Get a handle to the file
Dim file
set file = FSO.GetFile(Filepath)

' Get some info about the file
Dim FileSize
FileSize = file.Size

Response.Write "<p><b>File: " & Filename & " (size " & FileSize &_
" bytes)</b></p><hr>"
Response.Write "<pre>"

' Open the file
Dim TextStream
Set TextStream = file.OpenAsTextStream(ForReading, _
TristateFalse)

' Read the file line by line
Do While Not TextStream.AtEndOfStream

Dim Line,Temp
Line = TextStream.readline
Temp = Mid(Line, 329, 2)

if trim(Temp) <> "" then
response.Write ("fine")
end if

Loop

Response.Write "</pre><hr>"

Set TextStream = nothing

Else

Response.Write "<h3><i><font color=red> File " & Filename &_
" does not exist</font></i></h3>"

End If

Set FSO = nothing
%>
</PRE>

</body>
</html>

Phil i have tried to execute the vb.net but it is giving me the following error:

Source File: C:\Inetpub\Site\contentmu\vrprovider\vladdress.aspx Line: 7

I have already done that , code is :

Imports System.IO

<%
Const FileName As String = "/AGC-20070102-UPT.txt"
Dim FilePath As String = "//mu-bfs/manu/general/valProviderAddress" & FileName

If File.Exists(FilePath) Then
' Get a handle to the file
Dim file As New FileInfo(FilePath)

' Get some info about the file
Dim FileSize As Long = file.Length

Response.Write "<p><b>File: " & FileName & " (size " & FileSize & " bytes)</b></p><hr>"
Response.Write("<pre>")

' Open the file
Dim reader As TextReader
reader = file.OpenText()

' Read the file line by line
Dim Line As String
Do
Line = reader.ReadLine
If Mid(Line, 329, 2) <> " " Then
Response.Write("fine")
End If
Loop Until Line Is Nothing

Response.Write("</pre><hr>")
reader.Close()
Else
Response.Write "<h3><i><font color=red> File " & FileName & " does not exist</font></i></h3>"
End if%>

I have done that changes , now i am getting the following error

Server Error in '/Site' Application.
