Not particularly relevant but the above reminded me that you can do this:

using (var loFtpWebResponse = loFtpWebRequest.GetResponse())
>>using (var s = loFtpWebResponse.GetResponseStream())
>>using (var loStreamReader = new StreamReader(s))
>>            {
>>                // Load the files into the string builder
>>                loStringBuilder.Append(loStreamReader.ReadToEnd());
>>            }

I think I agree. Don't remember actually seeing this construct used anywhere.....
