// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

// Set the various properties to establish the connection.
ftp.Hostname = "ftp.example.com";
ftp.Username = "login";
ftp.Password = "password";

// If SSL/TLS is required..
// See http://www.cknotes.com/determining-ftp2-connection-settings/ 
// for more information.
ftp.AuthTls = true;
ftp.PassiveUseHostAddr = true;

// Connect to the FTP server:
bool success = ftp.ConnectOnly();
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

// Authenticate with the FTP server.
success = ftp.LoginAfterConnectOnly();

// To get file permissions in UNIX format, disallow MSLD:
ftp.AllowMlsd = false;

// To get file and sub-directory information, simply
// loop from 0 to ftp.GetDirCount() - 1
int i = 0;
int n = ftp.GetDirCount();
if (n < 0) {
    Debug.WriteLine(ftp.LastErrorText);
    return;

// Show the type of permissions information that is available.
// The two most common types are "mlsd" and "unix".  See the
// online reference documentation for more information.
if (n > 0) {
    Debug.WriteLine("The permissions format is: " + ftp.GetPermType(0));
}

while (i < n) {

    // Display the permissions and filename
    Debug.WriteLine(ftp.GetPermissions(i) + " " + ftp.GetFilename(i));

    i = i + 1;

// Assuming MLSD was possible, let's see the file permissions in MLSD format:
ftp.AllowMlsd = true;

// Clear the directory cache so we're forced to re-fetch the directory listing:
ftp.ClearDirCache();
