>I think we need some code of yours - the error you are getting is not related to Using - more a problem of type/casting

It is very simple:

                        Using loFtpWebResponse = loFtpWebRequest.GetResponse()

                            Using s = loFtpWebResponse.GetResponseStream()

                                Using loStreamReader = New StreamReader(s)

                                    ' Load the files into the string builder
                                    loStringBuilder.LoadString(loStreamReader.ReadToEnd())

                                End Using

                            End Using

                        End Using
