           Summary: WebClient.OpenRead() fails when trying to access an
                    anonymous ftp site
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.10.x

I have created a very simple example which works perfectly under .Net
Framework. In case of anonymous ftp sites, it is not necessary to set the
Credentials property of the WebClient object. But even when doing so, Mono
2.10.1 does not work as expected and it seems to be impossible to use
WebClient.OpenRead() for anonymous ftp site.

WebClient client=new WebClient();
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
byte[] buf=new byte[1024];

//client.Credentials=new NetworkCredential("anon","anon at me.com");
Stream strm=client.OpenRead("ftp://ftp.myftpsite.com/");//enter an ftp
site+file to open!
string strData = enc.GetString(buf);

Reproducible: Always

Steps to Reproduce:
1.Run the example

Actual Results:  
(a)without setting the WebClient object's Credentials property:
System.Net.WebException in System.Net.FtpWebRequest.CheckIfAborted()

(b)explicitly setting the WebClient object's Credentials property for anonymous
"System.ArgumentNullException: Argument cannot be null." in

Expected Results:  
No exception, simply download the corresponding remote file's content to
