(.NET Core C#) Get IMAP UID from Email HeaderDemonstrates how to get the IMAP UID from an email header. After fetching an email or header using IMAP, the UID is contained in the ckx-imap-uid header field.
// This example requires 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 = imap.Connect("imap.someMailServer.com"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // Login success = imap.Login("login","password"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // Select an IMAP mailbox success = imap.SelectMailbox("Inbox"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } bool fetchUids = true; // Get the message UIDs of all the emails in the mailbox Chilkat.MessageSet messageSet = imap.Search("ALL",fetchUids); if (imap.LastMethodSuccess != true) { Debug.WriteLine(imap.LastErrorText); return; } Chilkat.EmailBundle bundle = imap.FetchHeaders(messageSet); if (imap.LastMethodSuccess != true) { Debug.WriteLine(imap.LastErrorText); return; } // The UID of each fetched email header is available // in the ckx-imap-uid header field. int i = 0; int szBundle = bundle.MessageCount; Chilkat.MessageSet msOneMsg = new Chilkat.MessageSet(); while (i < szBundle) { Chilkat.Email email = bundle.GetEmail(i); // Build a message set containing one UID string uidStr = email.GetHeaderField("ckx-imap-uid"); msOneMsg.FromCompactString(uidStr); // Move this message to some other folder. success = imap.MoveMessages(msOneMsg,"someOtherFolder"); if (success != true) { Debug.WriteLine(imap.LastErrorText); // Exit the loop... i = szBundle; } i = i + 1; } // Disconnect from the IMAP server. success = imap.Disconnect(); |
