I have a situation which I cannot know how to resolve. Regular FTP connection using FtpWebRequest() would go as follow:

ftp://ftp.mysite.com/MyDirectory

                loFtpWebRequest = System.Net.FtpWebRequest.Create(New Uri(lcURI))
                loFtpWebRequest.Credentials = New System.Net.NetworkCredential(cUsername, cPassword)
                loFtpWebRequest.Method = System.Net.WebRequestMethods.Ftp.ListDirectoryDetails

If the client installs a FTP SSL certificate, then, the following would work:

ftps://ftp.mysite.com/MyDirectory

                loFtpWebRequest = System.Net.FtpWebRequest.Create(New Uri(lcURI))
                loFtpWebRequest.Credentials = New System.Net.NetworkCredential(cUsername, cPassword)
                loFtpWebRequest.Method = System.Net.WebRequestMethods.Ftp.ListDirectoryDetails
                loFtpWebRequest.EnableSsl = lSSL

But, I have a situation where the client has installed a FTP SSL certificate but under https. So, I thought by changing the lcURI to start with https:// instead of ftp:// would do. But, that gives an error:

"Unable to cast object of type 'System.Net.HttpWebRequest' to type 'System.Net.FtpWebRequest'."

The reason is that it detects that the URI starts with https and that conflicts with FtpWebRequest. So, how are we suppose to use FtpWebRequest when the URI starts with https?
