// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Imap imap = new Chilkat.Imap();

// Turn on session logging:
imap.KeepSessionLog = true;

// Connect to an IMAP server.
// Use TLS
imap.Ssl = true;
imap.Port = 993;
bool success = imap.Connect("imap.someMailServer.com");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Login
success = imap.Login("myLogin","myPassword");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Select an IMAP mailbox
success = imap.SelectMailbox("Inbox.RubyMail");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

Chilkat.MessageSet messageSet = null;

// Get the complete set of Uids for email in the selected mailbox.
messageSet = imap.GetAllUids();
if (imap.LastMethodSuccess != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Set the Deleted flag for each message.
// (ExpungeAndClose must be called to finalize the delete.)
success = imap.SetFlags(messageSet,"Deleted",1);
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Alternatively, the Deleted flag may be set for each UID
// individiually, but this is less efficient:
int i;
int n = messageSet.Count;
for (i = 0; i <= n - 1; i++) {
    success = imap.SetFlag(messageSet.GetId(i),messageSet.HasUids,"Deleted",1);
    if (success != true) {
        Debug.WriteLine(imap.LastErrorText);
        return;
    }

}

// Expunge and close the mailbox.
success = imap.ExpungeAndClose();
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Display the session log.
Debug.WriteLine(imap.SessionLog);

// Disconnect from the IMAP server.
success = imap.Disconnect();
