Reading a Delimited File Using ASP.Net and VB.Net - Code Explanation
(Page 5 of 6 )

To test this script you will be creating two files:  One .aspx file and the other, a .txt file.

  1. Open your notepad
  2. Copy the following complete code

<%--
 Beginning of script Reading a delimited text file written by G.Ajaykumar<
ajaykumar_g@hotmail.com>--%>

<%@Import Namespace="System.IO"%>
<script language="vb" runat="server">
Sub page_load(Sender As Object,e As EventArgs)
   Dim filetoread as string
   filetoread=server.mappath("readtest.txt")
   dim filestream as StreamReader
   filestream = File.Opentext(filetoread)
   Dim readcontents as String
   readcontents = fileStream.ReadToEnd()
   Dim textdelimiter as String
   textdelimiter = ","
   Dim splitout = Split(readcontents,textdelimiter)
      lblplaintext.text = readcontents & "<br>"
    dim i as integer
    for i=0 to Ubound(splitout)
  lblsplittext.Text &= "<b>Split </b>" & i+1 & ")   " & splitout(i)& "<br>"
    next
   filestream.Close()  
End Sub
</script>
<asp:label align="center" ForeColor="Maroon" Font-Names="Arial" BackColor="LemonChiffon" BorderColor="#0000C0" runat="server" id="lbldisplay" Font-Name="Verdana" text="Reading a delimited text file using ASP.NET/VB.NET coded by G.Ajaykumar" /><br />
<br /><br /><b>Plain Output</b><br />
<asp:label runat="server" id="lblplaintext" Font-Name="Verdana" /><br />
<b>Split Output</b><br />
<asp:label runat="server" id="lblsplittext" Font-Name="Verdana" />
<%-- End of script--%>

Save the file as readdelimit.aspx.

Now, create a textfile named readtest.txt and copy the following text to that file and save it:

History of the world, is the history of few men who had faith in themselves, that faith calls out the divinity, with in, you can do anything you fail only when you do not strive sufficiently to manifest the infinite power, if you have faith in all the three hundred and thirty millions, of your mythological gods and in all the gods which foreign has now and gain faith, in yourselfs,what ever you hink that you will be if you think weak weak, you will be,if you think yourselves strong strong you will ,be free and hope for nothing from any one.

readdelimit.aspx is the source file and readtest.txt is the delimited text file.  Dump these files to your wwwroot directory and run readlimit.aspx.  Thatís it!
