(C#) IMAP Search with THREAD SemanticsDemonstrates how to search an IMAP mailbox and return message numbers grouped together in parent/child relationships based on which messages are replies to others. Note: This example requires Chilkat v9.5.0.77 or greater.
// 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 your IMAP server and authenticate.. imap.Ssl = true; imap.Port = 993; bool success = imap.Connect("imap.mail.us-west-2.awsapps.com"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } success = imap.Login("myLogin","myPassword"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // Select a mailbox success = imap.SelectMailbox("Inbox"); if (success != true) { Debug.WriteLine(imap.LastErrorText); return; } // Search for all message having the letter 'a' somewhere in the Subject, // and return the messages as JSON. Chilkat.JsonObject json = imap.ThreadCmd("REFERENCES","UTF-8","SUBJECT a",true); if (imap.LastMethodSuccess == false) { Debug.WriteLine(imap.LastErrorText); return; } // The IMAP server will return a raw response with a format such as this: (2)(3 6 (4 23)(44 7 96)) // In tree form, it's like this: // // -- 2 // -- 3 // \-- 6 // |-- 4 // | \-- 23 // | // |-- 44 // \-- 7 // \-- 96 // // It means there are 2 main threads returned, but the 2nd thread splits into two sub-threads. // In total, we can think of it as 3 threads -- 2 main threads (with no parents) and one sub-thread w/ a parent. // // - The 1st thread contains the message 2, and has no parent thread. // - The 2nd thread contains the messages 3, 6, 4, 23, and has no parent thread. // - The 3rd thread contains the messages 44, 7, 96 and the parent thread is message 6. // // (Yes, this is all highly confusing...) // Chilkat will return the above sample response as JSON that looks like this: // { // "threads": [ // [2], // [3, 6, [4, 23], [44, 7, 96]] // ] // } // // Use this online tool to generate parsing code from sample JSON: // Generate Parsing Code from JSON // In this case, the online tool can help you get a feel for how to write the JSON parsing code.. int numThreads = json.SizeOfArray("threads"); Debug.WriteLine("The total number of top-level threads is " + Convert.ToString(numThreads)); // Let's say we wanted to get the messages in the thread 3, 6, 4, 23. // We always follow the 1st branch to the bottom, ignoring the other branches. // For example, if we had [3, 5, [4, 23, [55, 56, 57], [68, 69]], [44, 7, 96]] // then the thread would be 3, 5, 4, 43, 55, 56, 57 // For testing, let's substitute the response from the IMAP server with this sample: json.Load("{\"threads\": [[2], [3, 5, [4, 23, [55, 56, 57], [68, 69]], [44, 7, 96]]]}"); // Begin with the 2nd top-level thread, which is at index 1. Debug.WriteLine("Following the 2nd top level thread..."); Chilkat.JsonArray arr = json.ArrayOf("threads[1]"); int threadSize = arr.Size; int i = 0; while (i < threadSize) { // Do we have an array or integer at this position? if (arr.TypeAt(i) == 4) { // This is a sub-array. Chilkat.JsonArray subArr = arr.ArrayAt(i); // Follow the sub-array starting at the 1st position.. arr = subArr; i = 0; threadSize = arr.Size; } else { // Must be a single integer. Debug.WriteLine(Convert.ToString(arr.IntAt(i))); i = i + 1; } } // The output is: // // Following the 2nd top level thread... // 3 // 5 // 4 // 23 // 55 // 56 // 57 |
