FTP client class for .NET

Question

Anyone know of a good, hopefully free FTP class for use in .NET that can actually work behind an HTTP proxy or FTP gateway? The FtpWebRequest stuff in .NET is horrible at best, and I really don't want to roll my own here.

Answer 1

System.Net.WebClient can handle ftp urls, and it's a bit easier to work with. You can set credentials and proxy information with it, too.

Answer 2

I have no particular experience but sharptoolbox offer plenty implementations.

Answer 3

You can give "Indy.Sockets" a try. It can handle a lot of high level network protocols, including ftp.

Answer 4

The best one I've run across is edtFTP.net http://www.enterprisedt.com/products/edtftpnet/overview.html

If offers flexibility you don't get in the built-in classes

Answer 5

I have used http://sourceforge.net/projects/dotnetftpclient/ for quite a while now, and it does the job nicely. If you use a PASV connection, you shouldn't have any firewall issues. Not sure what an FTP gateway is, but I don't see how the HTTP Proxy would affect any FTP connection.

Answer 6

Our Rebex FTP works with proxies just fine. Following code shows how to connect to the FTP using HTTP proxy (code is taken from FTP tutorial page).

// initialize FTP client 
Ftp client = new Ftp();

// setup proxy details  
client.Proxy.ProxyType = FtpProxyType.HttpConnect;
client.Proxy.Host = proxyHostname;
client.Proxy.Port = proxyPort;

// add proxy username and password when needed 
client.Proxy.UserName = proxyUsername;
client.Proxy.Password = proxyPassword;

// connect, login 
client.Connect(hostname, port);
client.Login(username, password);

// do some work 
// ... 

// disconnect 
client.Disconnect();
