我正在为我的项目使用Mailkit库(Imap).
i'm using Mailkit library (Imap) for my project.
我可以通过SmtpClient轻松发送新消息.
I can comfortably send a new message by SmtpClient.
目前,我正在研究如何回复特定的邮件.并可以在该回复邮件中添加更多收件人吗?
currently I'm digging about how to reply to a particular mail. and is it possible to add more recipients to that reply mail ?
@jstedfast感谢您的精彩:)
@jstedfast thanks for the wonderful one :)
推荐答案回复邮件非常简单.在大多数情况下,您将以与创建其他任何消息相同的方式来创建回复消息.仅有一些细微差别:
Replying to a message is fairly simple. For the most part, you'd just create the reply message the same way you'd create any other message. There are only a few slight differences:
如果此逻辑要用代码表示,则可能看起来像这样:
If this logic were to be expressed in code, it might look something like this:
public static MimeMessage Reply (MimeMessage message, bool replyToAll) { var reply = new MimeMessage (); // reply to the sender of the message if (message.ReplyTo.Count > 0) { reply.To.AddRange (message.ReplyTo); } else if (message.From.Count > 0) { reply.To.AddRange (message.From); } else if (message.Sender != null) { reply.To.Add (message.Sender); } if (replyToAll) { // include all of the other original recipients - TODO: remove ourselves from these lists reply.To.AddRange (message.To); reply.Cc.AddRange (message.Cc); } // set the reply subject if (!message.Subject.StartsWith ("Re:", StringComparison.OrdinalIgnoreCase)) reply.Subject = "Re:" + message.Subject; else reply.Subject = message.Subject; // construct the In-Reply-To and References headers if (!string.IsNullOrEmpty (message.MessageId)) { reply.InReplyTo = message.MessageId; foreach (var id in message.References) reply.References.Add (id); reply.References.Add (message.MessageId); } // quote the original message text using (var quoted = new StringWriter ()) { var sender = message.Sender ?? message.From.Mailboxes.FirstOrDefault (); quoted.WriteLine ("On {0}, {1} wrote:", message.Date.ToString ("f"), !string.IsNullOrEmpty (sender.Name) ? sender.Name : sender.Address); using (var reader = new StringReader (message.TextBody)) { string line; while ((line = reader.ReadLine ()) != null) { quoted.Write ("> "); quoted.WriteLine (line); } } reply.Body = new TextPart ("plain") { Text = quoted.ToString () }; } return reply; }注意:此代码假定message.TextBody不为null.很有可能发生这种情况,尽管这种可能性很小(这意味着该消息不包含text/plain正文).
Note: This code assumes that message.TextBody is not null. It's possible, although fairly unlikely, that this could happen (meaning that the message does not contain a text/plain body).
