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

ftp.Hostname = "www.chilkatsoft.com";
ftp.Username = "MyLogin";

// Connect and login to the FTP server.
bool success = ftp.Connect();
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);

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

// Delete all files with filenames matching "ftp_*.asp"
int numDeleted = ftp.DeleteMatching("ftp_*.asp");
if (numDeleted < 0) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}

success = ftp.Disconnect();

Debug.WriteLine(Convert.ToString(numDeleted) + " Files Deleted!");
