La lecture des emails de Gmail en C#

À l'aide de la bibliothèque à partir de: https://github.com/pmengal/MailSystem.NET

Voici mon code complet de l'échantillon:

E-Mail Référentiel

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<Message> GetAllMails(string mailBox)
        {
            return GetMails(mailBox, "ALL").Cast<Message>();
        }

        public IEnumerable<Message> GetUnreadMails(string mailBox)
        {
            return GetMails(mailBox, "UNSEEN").Cast<Message>();
        }

        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;
        }
    }
}

Utilisation

[TestMethod]
public void ReadImap()
{
    var mailRepository = new MailRepository(
                            "imap.gmail.com",
                            993,
                            true,
                            "[email protected]",
                            "yourPassword"
                        );

    var emailList = mailRepository.GetAllMails("inbox");

    foreach (Message email in emailList)
    {
        Console.WriteLine("<p>{0}: {1}</p><p>{2}</p>", email.From, email.Subject, email.BodyHtml.Text);
        if (email.Attachments.Count > 0)
        {
            foreach (MimePart attachment in email.Attachments)
            {
                Console.WriteLine("<p>Attachment: {0} {1}</p>", attachment.ContentName, attachment.ContentType.MimeType);
            }
        }
    }
}

Un autre exemple, cette fois en utilisant MailKit

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<string> GetUnreadMails()
{
var messages = new List<string>();
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<string> GetAllMails()
{
var messages = new List<string>();
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;
}
}

Utilisation

[Test]
public void GetAllEmails()
{
var mailRepository = new MailRepository("imap.gmail.com", 993, true, "[email protected]", "YOURPASSWORDHERE");
var allEmails = mailRepository.GetAllMails();
foreach(var email in allEmails)
{
Console.WriteLine(email);
}
Assert.IsTrue(allEmails.ToList().Any());
}
