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

// See Get Yahoo Mail OAuth2 Access Token for Desktop App 
// for sample code showing how to obtain a Yahoo Mail access token.

// In this example, our access token was previously saved to the following file which contains JSON like this:
// {
//   "access_token": "kCVQdnOdul...LHucA--",
//   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
//   "expires_in": 3600,
//   "token_type": "bearer",
//   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
// }

Chilkat.JsonObject json = new Chilkat.JsonObject();
bool success = json.LoadFile("qa_data/tokens/yahooMail.json");
if (success != true) {
    Debug.WriteLine("Failed to load GMail access token file.");
    return;
}

string accessToken = json.StringOf("access_token");

// Do OAuth2 authentication by using the access token as the password in the Login method below...
Chilkat.Imap imap = new Chilkat.Imap();

imap.Port = 993;

// Connect to the Yahoo IMAP server.
success = imap.Connect("imap.mail.yahoo.com");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Indicate that XOAUTH2 authentication is to be used:
imap.AuthMethod = "XOAUTH2";

// Login
// Use the email address of the GMail account that granted authorization.
success = imap.Login("user@yahoo.com",accessToken);
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
}

    Debug.WriteLine("Successfully authenticated with Yahoo IMAP using XOAUTH2!");
}

// The ListMailboxes method returns a Mailboxes object
// that contains the collection of mailboxes.
// It accepts two arguments: a refName and a wildcardedMailbox.

string refName = "";
// refName is usually set to an empty string.
// A non-empty reference name argument is the name of a mailbox or a level of
// mailbox hierarchy, and indicates the context in which the mailbox
// name is interpreted.

// Select all mailboxes matching this pattern:
string wildcardedMailbox = "*";

Chilkat.Mailboxes mboxes = imap.ListMailboxes(refName,wildcardedMailbox);
if (imap.LastMethodSuccess == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

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

// Sample output looks like this:

// Archive
// Bulk Mail
// Draft
// Inbox
// Inbox/emailsWithAttach
// Inbox/test
// Sent
// Trash

// Disconnect from the IMAP server.
