Is it possible to use WebClient.DownloadFile and WebClient.UploadFile to a
FTP server that requires a user name and password?

If yes, how is the authentication information passed to the server?

What was the source of your information?

using System;
using System.Net;

public class ftpWebRequest : WebRequest {
//implement ftp-specific protocol methods and properties
}

public class ftpCreator : IWebRequestCreate
{
public WebRequest Create(Uri uri)
{
return new ftpWebRequest();
}
}

public class RegisterPrefixExample
{

public static void Main()
{

ftpCreator creator = new ftpCreator();
WebRequest.RegisterPrefix("ftp://", creator);
WebRequest wr = WebRequest.Create("ftp://testFile");
Console.WriteLine(wr);
}
}

Thanks for netnoobie's input.

Hi Thom,

As for the WebClient class is using the WebRequest component internally, so
it can only access remote resources through the existing registred
WebRequest components. For .net 1.1, there is only Http/https based or
local File:// protocol based component avaliable. So we can not use the
WebClient class to access remote resource through FTP protocol. Also, in
..NET 2.0 there has provided FtpWebRequest and FtpWebResponse class as
build-in components which can help performing FTP resource accessing.

Thank you everyone.

I was in a "blind spot" and just didn't see it. It is monumentally simple.

Download ...
using System.Net ;
WebClient wc = new WebClient( );
wc.Credentials = new NetworkCredential( "someaccount", "somepassword" );
wc.DownloadFile( "ftp://ftp.somedomain.tld/somefile.txt",
@"c:\temp\somefile.txt" );

Upload ...

Using System.Net ;
WebClient wc = new WebClient( );
wc.Credentials = new NetworkCredential( "someaccount", "somepassword" );
wc.UploadFile( "ftp://ftp.somedomain.tld/somefile.txt",
@"c:\temp\somefile.txt" );
