using c# .net libraries to check for IMAP messages from gmail servers [closed]

Question

Does anyone have any sample code in that makes use of the .Net framework that connects to googlemail servers via IMAP SSL to check for new emails?

I'd recommend looking at MailKit as it is probably the most robust mail library out there and it's Open Source (MIT).

One of the awesome things about MailKit is that all network APIs are cancelable (something I haven't seen available in any other IMAP library).

It's also the only library that I know of that supports threading of messages.

using System; using System.Net; using System.Threading;  using MailKit.Net.Imap; using MailKit.Search; using MailKit; using MimeKit;  namespace TestClient {     class Program     {         public static void Main (string[] args)         {             using (var client = new ImapClient ()) {                 using (var cancel = new CancellationTokenSource ()) {                     client.Connect ("imap.gmail.com", 993, true, cancel.Token);                      // If you want to disable an authentication mechanism,                     // you can do so by removing the mechanism like this:                     client.AuthenticationMechanisms.Remove ("XOAUTH");                      client.Authenticate ("joey", "password", cancel.Token);                      // The Inbox folder is always available...                     var inbox = client.Inbox;                     inbox.Open (FolderAccess.ReadOnly, cancel.Token);                      Console.WriteLine ("Total messages: {0}", inbox.Count);                     Console.WriteLine ("Recent messages: {0}", inbox.Recent);                      // download each message based on the message index                     for (int i = 0; i < inbox.Count; i++) {                         var message = inbox.GetMessage (i, cancel.Token);                         Console.WriteLine ("Subject: {0}", message.Subject);                     }                      // let's try searching for some messages...                     var query = SearchQuery.DeliveredAfter (DateTime.Parse ("2013-01-12"))                         .And (SearchQuery.SubjectContains ("MailKit"))                         .And (SearchQuery.Seen);                      foreach (var uid in inbox.Search (query, cancel.Token)) {                         var message = inbox.GetMessage (uid, cancel.Token);                         Console.WriteLine ("[match] {0}: {1}", uid, message.Subject);                     }                      client.Disconnect (true, cancel.Token);                 }             }         }     } }
