How to change the 'Folder' in IMAP

Question

My aim is to learn how to change the 'Folder', how to read and delete the emails from the 'Folder' I want?

Answer 1

To change the IMAP folder you simple use the Select method:

using (Imap imap = new Imap())
{
    imap.ConnectSSL("imap.example.com");
    imap.UseBestLogin("user", "password");

    imap.Select("Sent items");

    List<long> uids = imap.GetAll();

    imap.Close();
}

To use inbox SelectInbox can be used.

You can use GetFolders to list all folders and CommonFolders class to recognize standard folder (even when they are localized):

List<FolderInfo> folders = imap.GetFolders();

CommonFolders common = new CommonFolders(folders);

string inboxName = common.Inbox.Name;
string sentName = common.Sent.Name;
string spamName = common.Spam.Name;

// You can now select those e.g.:
imap.Select(common.Sent);
