Default ports for FTP

By default FTP uses port 21 for control channel:

// C# version

using (Ftp client = new Ftp())
{
    client.Connect("ftp.example.org");

    //...

    client.Close();
}
' VB.NET version

Using client As New Ftp()
	client.Connect("ftp.example.org")

	'...

	client.Close()
End Using

By default FTPS uses port 990 for control channel:

// C# version

using (Ftp client = new Ftp())
{
    client.ConnectSSL("ftp.example.org");

    //...

    client.Close();
}
' VB.NET version

Using client As New Ftp()
	client.ConnectSSL("ftp.example.org")

	'...

	client.Close()
End Using

If your FTP or FTPS server is running on different port just use overladed version of Connect and ConnectSSL:

// C# version

client.Connect("ftp.example.org", 999);
client.ConnectSSL("ftp.example.org", 999);
' VB.NET version

client.Connect("ftp.example.org", 999)
client.ConnectSSL("ftp.example.org", 999)
