// Connect and login to the FTP server.
bool success = await ftp.ConnectAsync();

// Change to the remote directory where the files to be deleted are located.
// for the FTP account.
success = await ftp.ChangeRemoteDirAsync("junk");
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);

// Delete all files with filenames matching "ftp_*.asp"
int numDeleted = await ftp.DeleteMatchingAsync("ftp_*.asp");
if (numDeleted < 0) {
