每次在c#应用程序中从邮箱接收新的未读邮件
每次在c#应用程序中从邮箱接收新的未读邮件
提问于 2016-05-10 06:24:32
我想实现和这个一样的功能：
这很好用。该方法"NewMessageReceived“成功调用每一个新的邮件接收。
但问题是我拿不到邮件。在这种方法中，我只得到了收件箱的总数。
使用库的代码：MailSystem.net
我的守则如下：
Imap4Client _imap;
public static int cnt = 0;
protected void Application_Start(object sender, EventArgs e)
{
var worker = new BackgroundWorker();
worker.DoWork += new DoWorkEventHandler(StartIdleProcess);
if (worker.IsBusy)
worker.CancelAsync();
worker.RunWorkerAsync();
}
private void StartIdleProcess(object sender, DoWorkEventArgs e)
{
if (_imap != null && _imap.IsConnected)
{
_imap.StopIdle();
_imap.Disconnect();
}
_imap = new Imap4Client();
_imap.ConnectSsl(ConfigurationManager.AppSettings["IncomingServerName"], Convert.ToInt32(ConfigurationManager.AppSettings["InPort"]));
_imap.Login(ConfigurationManager.AppSettings["EmailAddress"], ConfigurationManager.AppSettings["Password"]);
var inbox = _imap.SelectMailbox("INBOX");
_imap.NewMessageReceived += new NewMessageReceivedEventHandler(NewMessageReceived);
inbox.Subscribe();
_imap.StartIdle();
}
public static void NewMessageReceived(object source, NewMessageReceivedEventArgs e)
{
cnt = e.MessageCount; //Inbox Count
//here i want to fetch all unread mail from inbox
}我发现了以下获取未读邮件的解决方案：

它是说我要使用MailKit库。由于我已经在使用MailSystem.net库，是否有任何方法可以通过只使用一个库来实现我的需求？
我也准备使用任何其他图书馆。
请给我建议。谢谢

是的，是用单个库得到的：MailKit
查看global.asax文件的以下代码：
static CancellationTokenSource _done;
ImapClient _imap;
protected void Application_Start(object sender, EventArgs e)
{
var worker = new BackgroundWorker();
worker.DoWork += new DoWorkEventHandler(StartIdleProcess);
if (worker.IsBusy)
worker.CancelAsync();
worker.RunWorkerAsync();
}
private void StartIdleProcess(object sender, DoWorkEventArgs e)
{
_imap = new ImapClient();
_imap.Connect(ConfigurationManager.AppSettings["IncomingServerName"], Convert.ToInt32(ConfigurationManager.AppSettings["InPort"]), Convert.ToBoolean(ConfigurationManager.AppSettings["IncomingIsSSL"]));
_imap.AuthenticationMechanisms.Remove("XOAUTH");
_imap.Authenticate(ConfigurationManager.AppSettings["EmailAddress"], ConfigurationManager.AppSettings["Password"]);
_imap.Inbox.Open(FolderAccess.ReadWrite);
_imap.Inbox.MessagesArrived += Inbox_MessagesArrived;
_done = new CancellationTokenSource();
_imap.Idle(_done.Token);
}
static void Inbox_MessagesArrived(object sender, EventArgs e)
{
var folder = (ImapFolder)sender;
//_done.Cancel(); // Stop idle process
using (var client = new ImapClient())
{
client.Connect(ConfigurationManager.AppSettings["IncomingServerName"], Convert.ToInt32(ConfigurationManager.AppSettings["InPort"]), Convert.ToBoolean(ConfigurationManager.AppSettings["IncomingIsSSL"]));
// disable OAuth2 authentication unless you are actually using an access_token
client.AuthenticationMechanisms.Remove("XOAUTH2");
client.Authenticate(ConfigurationManager.AppSettings["EmailAddress"], ConfigurationManager.AppSettings["Password"]);
int tmpcnt = 0;
client.Inbox.Open(FolderAccess.ReadWrite);
foreach (var uid in client.Inbox.Search(SearchQuery.NotSeen))
{
try
{
var message = client.Inbox.GetMessage(uid);
client.Inbox.SetFlags(uid, MessageFlags.Seen, true);
List<byte[]> listAttachment = new List<byte[]>();
if (message.Attachments.Count() > 0)
{
foreach (var objAttach in message.Attachments)
{
using (MemoryStream ms = new MemoryStream())
{
((MimeKit.ContentObject)(((MimeKit.MimePart)(objAttach)).ContentObject)).Stream.CopyTo(ms);
byte[] objByte = ms.ToArray();
listAttachment.Add(objByte);
}
}
}
string subject = message.Subject;
string text = message.TextBody;
var hubContext = GlobalHost.ConnectionManager.GetHubContext<myHub>();
hubContext.Clients.All.modify("fromMail", text);
tmpcnt++;
}
catch (Exception)
{ }
}
client.Disconnect(true);
}
}现在，我能够接收新的邮件到达事件，也能够在该事件中获取未读邮件。谢谢MailKit。
