(C#) Search IMAP Mailbox for Email Matching CriteriaSearching an IMAP mailbox for messages that match search criteria.
// 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("myLogin","myPassword"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // Select an IMAP mailbox success = imap.SelectMailbox("Inbox"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } Chilkat.MessageSet messageSet = null; // We can choose to fetch UIDs or sequence numbers. bool fetchUids = true; // Here are examples of different search criteria: // Return all messages. string allMsgs = "ALL"; // Search for already-answered emails. string answered = "ANSWERED"; // Search for messages on a specific date. // The date string is DD-Month-YYYY where Month is // Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, or Dec. string onDate = "SENTON 05-Mar-2007"; // Search for messages between two dates. SENTBEFORE // finds emails sent before a date, and SENTSINCE finds // email sent on or after a date. The "AND" operation // is implied by joining criteria, separated by spaces. string betweenDates = "SENTSINCE 01-Mar-2007 SENTBEFORE 05-Mar-2007"; // Another example of AND: find all unanswered emails // sent after 04-Mar-2007 with "Problem" in the subject: string complexSearch1 = "UNANSWERED SENTSINCE 04-Mar-2007 Subject \"Problem\""; // Find messages with a specific string in the body: string bodySearch = "BODY \"problem solved\""; // Using OR. The syntax is OR <criteria1> <criteria2>. // The "OR" comes first, followed by each criteria. // For example, to match all emails with "Help" or "Question" in the subject. // You'll notice that literal strings may be quoted or unquoted. // If a literal contains SPACE characters, quote it: string orSearch = "OR SUBJECT Help SUBJECT Question"; // ---------------------------------------------- // Strings are case-insensitive when searching.... // ---------------------------------------------- // Find all emails sent from yahoo.com addresses: string fromSearch = "FROM yahoo.com"; // Find all emails sent from anyone with "John" in their name: string johnSearch = "FROM John"; // Find emails with the RECENT flag set: string recentSearch = "RECENT"; // Find emails that don't have the recent flag set: string notRecentSearch = "NOT RECENT"; // This is synonymous with "OLD": string oldSearch = "OLD"; // Find all emails marked for deletion: string markedForDeleteSearch = "DELETED"; // Find all emails having a specified header field with a value // containing a substring: string headerSearch = "HEADER DomainKey-Signature paypal.com"; // Find any emails having a specific header field. If the // 2nd argument to the "HEADER" criteria is an empty string, // any email having the header field is returned regardless // of the header field's content. // Find any emails with a DomainKey-Signature field: string headerExistsSearch = "HEADER DomainKey-Signature \"\""; // Find NEW emails: these are emails that have the RECENT flag // set, but not the SEEN flag: string newSearch = "NEW"; // Find emails larger than a certain number of bytes: string sizeLargerSearch = "LARGER 500000"; // Find emails marked as seen or not already seen: string seenSearch = "SEEN"; string notSeenSearch = "NOT SEEN"; // Find emails having a given substring in the TO header field: string toSearch = "TO support@chilkatsoft.com"; // A more long-winded way to do the same thing: string toSearch2 = "HEADER TO support@chilkatsoft.com"; // Find emails smaller than a size in bytes: string smallerSearch = "SMALLER 30000"; // Find emails that have a substring anywhere in the header // or body: string fullSubstringSearch = "TEXT \"Zip Component\""; // Pass any of the above strings here to test a search: messageSet = imap.Search(orSearch,fetchUids); if (imap.LastMethodSuccess == false) { Debug.WriteLine(imap.LastErrorText); return; } // Fetch the email headers into a bundle object: Chilkat.EmailBundle bundle = null; bundle = imap.FetchHeaders(messageSet); if (imap.LastMethodSuccess == false) { Debug.WriteLine(imap.LastErrorText); return; } // Display the Subject and From of each email. int i = 0; while (i < bundle.MessageCount) { Chilkat.Email email = null; email = bundle.GetEmail(i); Debug.WriteLine(email.GetHeaderField("Date")); Debug.WriteLine(email.Subject); Debug.WriteLine(email.From); Debug.WriteLine("--"); i = i + 1; } // Disconnect from the IMAP server. success = imap.Disconnect(); |
