Demonstrates how to list subscribed mailboxes, and unsubscribe/subscribe to a mailbox.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

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

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

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

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

// First examine the already subscribed mailboxes.
string refName = "";
string wildcardedMailbox = "*";

// Alternatively, the ListMailboxes method can be called to list all mailboxes (both subscribed and unsubscribed).
Chilkat.Mailboxes mboxes = await imap.ListSubscribedAsync(refName,wildcardedMailbox);
if (imap.LastMethodSuccess != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

int i;
for (i = 0; i <= mboxes.Count - 1; i++) {
    Debug.WriteLine(mboxes.GetName(i));
}

Debug.WriteLine("----");

// Sample output.

// INBOX
// INBOX/recent
// INBOX/misc
// INBOX/misc/solutions
// ...
// Outbox
// Deleted Items
// Sent Items
// Drafts
// Junk E-mail
// Trash
// Sent
// Templates

// Let's unsubscribe to "INBOX/misc/solutions".
success = await imap.UnsubscribeAsync("INBOX/misc/solutions");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Get the list of subscribed mailboxes again to verify that "INBOX/misc/solutions" is missing.
mboxes = await imap.ListSubscribedAsync("","INBOX/misc*");
if (imap.LastMethodSuccess != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

for (i = 0; i <= mboxes.Count - 1; i++) {
    Debug.WriteLine(mboxes.GetName(i));
}

Debug.WriteLine("----");

// Re-subscribe to "INBOX/misc/solutions".
success = await imap.SubscribeAsync("INBOX/misc/solutions");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Get the list of subscribed mailboxes again to verify that "INBOX/misc/solutions" is back in the list.
mboxes = await imap.ListSubscribedAsync("","INBOX/misc*");
if (imap.LastMethodSuccess != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

for (i = 0; i <= mboxes.Count - 1; i++) {
    Debug.WriteLine(mboxes.GetName(i));
}

Debug.WriteLine("----");

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