I am trying to read emails from Gmail. I have tried every API / open source project I can find, and can not get any of them working.
Does anyone have a sample of working code that will allow me to authenticate and download emails from a Gmail account?
Final working version posted below: https://stackoverflow.com/a/19570553/550198
Using the library from: https://github.com/pmengal/MailSystem.NET
Here is my complete code sample:
using System.Collections.Generic; using System.Linq; using ActiveUp.Net.Mail; namespace GmailReadImapEmail { public class MailRepository { private Imap4Client client; public MailRepository(string mailServer, int port, bool ssl, string login, string password) { if (ssl) Client.ConnectSsl(mailServer, port); else Client.Connect(mailServer, port); Client.Login(login, password); } public IEnumerable GetAllMails(string mailBox) { return GetMails(mailBox, "ALL").Cast(); } public IEnumerable GetUnreadMails(string mailBox) { return GetMails(mailBox, "UNSEEN").Cast(); } protected Imap4Client Client { get { return client ?? (client = new Imap4Client()); } } private MessageCollection GetMails(string mailBox, string searchPhrase) { Mailbox mails = Client.SelectMailbox(mailBox); MessageCollection messages = mails.SearchParse(searchPhrase); return messages; } } } [TestMethod] public void ReadImap() { var mailRepository = new MailRepository( "imap.gmail.com", 993, true, "yourEmailAddress@gmail.com", "yourPassword" ); var emailList = mailRepository.GetAllMails("inbox"); foreach (Message email in emailList) { Console.WriteLine("{0}: {1}
{2}
", email.From, email.Subject, email.BodyHtml.Text); if (email.Attachments.Count > 0) { foreach (MimePart attachment in email.Attachments) { Console.WriteLine("Attachment: {0} {1}
", attachment.ContentName, attachment.ContentType.MimeType); } } } } public class MailRepository : IMailRepository { private readonly string mailServer, login, password; private readonly int port; private readonly bool ssl; public MailRepository(string mailServer, int port, bool ssl, string login, string password) { this.mailServer = mailServer; this.port = port; this.ssl = ssl; this.login = login; this.password = password; } public IEnumerable GetUnreadMails() { var messages = new List(); using (var client = new ImapClient()) { client.Connect(mailServer, port, ssl); // Note: since we don't have an OAuth2 token, disable // the XOAUTH2 authentication mechanism. client.AuthenticationMechanisms.Remove("XOAUTH2"); client.Authenticate(login, password); // The Inbox folder is always available on all IMAP servers... var inbox = client.Inbox; inbox.Open(FolderAccess.ReadOnly); var results = inbox.Search(SearchOptions.All, SearchQuery.Not(SearchQuery.Seen)); foreach (var uniqueId in results.UniqueIds) { var message = inbox.GetMessage(uniqueId); messages.Add(message.HtmlBody); //Mark message as read //inbox.AddFlags(uniqueId, MessageFlags.Seen, true); } client.Disconnect(true); } return messages; } public IEnumerable GetAllMails() { var messages = new List(); using (var client = new ImapClient()) { client.Connect(mailServer, port, ssl); // Note: since we don't have an OAuth2 token, disable // the XOAUTH2 authentication mechanism. client.AuthenticationMechanisms.Remove("XOAUTH2"); client.Authenticate(login, password); // The Inbox folder is always available on all IMAP servers... var inbox = client.Inbox; inbox.Open(FolderAccess.ReadOnly); var results = inbox.Search(SearchOptions.All, SearchQuery.NotSeen); foreach (var uniqueId in results.UniqueIds) { var message = inbox.GetMessage(uniqueId); messages.Add(message.HtmlBody); //Mark message as read //inbox.AddFlags(uniqueId, MessageFlags.Seen, true); } client.Disconnect(true); } return messages; } } [Test] public void GetAllEmails() { var mailRepository = new MailRepository("imap.gmail.com", 993, true, "YOUREMAILHERE@gmail.com", "YOURPASSWORDHERE"); var allEmails = mailRepository.GetAllMails(); foreach(var email in allEmails) { Console.WriteLine(email); } Assert.IsTrue(allEmails.ToList().Any()); } You don't need any extra 3rd Party Libraries. You can read the data from API that Gmail has provided here: https://mail.google.com/mail/feed/atom
The response in XML format can be handled by the code below:
try { System.Net.WebClient objClient = new System.Net.WebClient(); string response; string title; string summary; //Creating a new xml document XmlDocument doc = new XmlDocument(); //Logging in Gmail server to get data objClient.Credentials = new System.Net.NetworkCredential("Email", "Password"); //reading data and converting to string response = Encoding.UTF8.GetString( objClient.DownloadData(@"https://mail.google.com/mail/feed/atom")); response = response.Replace( @"", @""); //loading into an XML so we can get information easily doc.LoadXml(response); //nr of emails nr = doc.SelectSingleNode(@"/feed/fullcount").InnerText; //Reading the title and the summary for every email foreach (XmlNode node in doc.SelectNodes(@"/feed/entry")) { title = node.SelectSingleNode("title").InnerText; summary = node.SelectSingleNode("summary").InnerText; } } catch (Exception exe) { MessageBox.Show("Check your network connection"); } Have you tried POP3 Email Client with full MIME Support ?
If you don't it's a very good example for you. As an alternativ;
.NET class library in C# for communicating with POP3 servers. Easy to use but yet powerful. Includes a robust MIME parser backed by several hundred test cases. For more information, visit our project homepage.
You can also try Mail.dll IMAP client.
It supports all Gmail IMAP protocol extensions:
Please note that Mail.dll is a commercial product, I've developed.
