ASP.NET File

Hey,

I ahve a asp.net web page. I want it to edit a file on the server. How could I do this?

I tried this code :

Code:

---

        Dim file_name As String = ("http://localhost/cassgroupmainpage/" & ListBox1.SelectedValue & "/" & ListBox2.SelectedValue & ".xml")
        Dim stream_reader As New IO.StreamReader(file_name)
        Dim a As String
        a = stream_reader.ReadToEnd()
        stream_reader.Close()
        a = Replace(a, "</posts>", "")
        Dim b As String
        b = "<post>"
        b = (b + vbCrLf + "Posted by" + TextBox4.Text + vbCrLf + vbCrLf + "Posted date " + System.DateTime.Today() + vbCrLf + "Message : " + vbCrLf + TextBox2.Text + "</post>" + vbCrLf + "</posts>")
        Dim file_name1 As String = ("http://localhost/cassgroupmainpage/" & ListBox1.SelectedValue & "/" & ListBox2.SelectedValue & ".xml")
        Dim stream_writer As New IO.StreamWriter(file_name1, False)
        stream_writer.Write(b)
        stream_writer.Close()
