the .NET Framwork supports FTP via the FtpWebRequest since version 2.0. No support for SFTP yet.

If you need both FTP and SFTP you have to try a third party component. There is an open source implementation of SFTP from Tamir Gal which is often recommended. Or you can try one of commercial SFTP components such as our Rebex SFTP.

Following code is taken from Rebex SFTP tutorial page:

// create client, connect and log in 
Sftp client = new Sftp();
client.Connect(hostname);
client.Login(username, password);

// upload the content of 'c:\data' directory and all subdirectories 
// to the '/wwwroot' directory at the server 
client.PutFiles(@"c:\data\*", "/wwwroot", SftpBatchTransferOptions.Recursive);

client.Disconnect();

If you are not sure whether you will need FTPS or SFTP you can check the Rebex File Transfer Pack which includes both. The FTP API is almost identical to the SFTP one.
