Simple example to upload a file to an FTP server using passive mode.

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

bool success;

// Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(ftp.LastErrorText);
    return;
}

ftp.Hostname = "www.example-code.com";
ftp.Username = "****";
ftp.Password = "****";

// The default data transfer mode is "Active" as opposed to "Passive".
// Change it to Passive by setting the Passive property:
ftp.Passive = true;

// Connect and login to the FTP server.
success = ftp.Connect();
if (success != true) {
    MessageBox.Show(ftp.LastErrorText);
    return;
}

// Change to the remote directory where the file will be uploaded.
success = ftp.ChangeRemoteDir("junk");
if (success != true) {
    MessageBox.Show(ftp.LastErrorText);
    return;
}

// Upload a file.
string localFilename;
localFilename = "hamlet.xml";
string remoteFilename;
remoteFilename = "hamlet.xml";

success = ftp.PutFile(localFilename,remoteFilename);
if (success != true) {
    MessageBox.Show(ftp.LastErrorText);
    return;
}

ftp.Disconnect();

MessageBox.Show("File Uploaded!");
