Answer 1

When talking about "secure ftp" please clarify whether you mean SFTP or FTPS. These are two different protocols as described in this article .

 

In any case, SecureBlackbox offers the most feature-rich components for both FTPS and SFTP for .NET.

Answer 2

FTPS is supported by the .NET Classes.  To use this set the EnableSSL property as outlined in this documentation. http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.enablessl.aspx

 

Answer 3

Secure FTP may can stand for either SSH SFTP or FTP/SSL. THe following examples show you how to upload files with both protocols using Ultimate SFTP and Ultimate FTP libs

SSH SFTP:

 

// Create a new instance.
Sftp client = new Sftp();
// Connect to the SFTP server.
client.Connect("localhost");
// Authenticate.
client.Authenticate("test", "test");
// ...
// Upload all files and subdirectories from local folder 'c:\temp' to the remote dir '/temp'
client.UploadFiles("c:\\temp", "/temp");
// Upload all directories, subdirectories, and files that match the specified search pattern from local folder 'c:\myfolder2' to remote folder '/myfolder2'.
client.UploadFiles("c:\\myfolder2", "/myfolder2", "*.cs");
// or you can simply put wildcard masks in the source path, our component will automatically parse it.
// upload all *.css files from local folder 'c:\myfolder2' to remote folder '/myfolder2'.
client.UploadFiles("c:\\myfolder2\\*.css", "/myfolder2");
// Upload *.cs and *.vb files from local folder 'c:\myfolder2' to remote folder '/myfolder2'.
client.UploadFiles("c:\\myfolder2\\*.cs;*.vb", "/myfolder2");
// ...
// Disconnect.
client.Disconnect();

FTP/SSL:

// Create a new instance.
Ftp client = new Ftp();
// Connect to the FTP server.
client.Connect("localhost");
// Authenticate.
client.Authenticate("test", "test");
// ...
// Upload all files and subdirectories from local folder 'c:\temp' to the remote dir '/temp'
client.UploadFiles("c:\\temp", "/temp");
// Upload all directories, subdirectories, and files that match the specified search pattern from local folder 'c:\myfolder2' to remote folder '/myfolder2'.
client.UploadFiles("c:\\myfolder2", "/myfolder2", "*.cs");
// or you can simply put wildcard masks in the source path, our component will automatically parse it.
// upload all *.css files from local folder 'c:\myfolder2' to remote folder '/myfolder2'.
client.UploadFiles("c:\\myfolder2\\*.css", "/myfolder2");
// Upload *.cs and *.vb files from local folder 'c:\myfolder2' to remote folder '/myfolder2'.
client.UploadFiles("c:\\myfolder2\\*.cs;*.vb", "/myfolder2");
// ...
// Disconnect.
client.Disconnect();
