C# example showing how to get information about files and subdirectories in the current remote FTP directory.

}

//  The ListPattern property is our directory listing filter.
//  The default value is "*", which includes everything.
textBox1.Text += ftp.ListPattern + "\r\n";

//  To get file and sub-directory information, simply
//  loop from 0 to ftp.NumFilesAndDirs - 1
