[英]MailSystem.Net is there a way to check the status (if it is read or unread) of an email?
[英]How mark gmail message as unread (unseen) MailSystem.NET
我搜索了很多如何從gmail閱讀電子郵件,然后將其標記為未讀(看不見),現在我發現我想與大家分享。

添加引用:activeup.net.common,activeup.net.imap4,activeup.net.mail
碼:
Imap4Client imap = new Imap4Client();
imap.ConnectSsl("imap.gmail.com", 993);
imap.Login("aaaaa@gmail.com", "xxxxxxx");
imap.Command("capability");
Mailbox inbox = imap.SelectMailbox("inbox");
int[] ids = inbox.Search("UNSEEN");
if (ids.Length > 0)
{
ActiveUp.Net.Mail.Message msg_first = inbox.Fetch.MessageObject(ids[0]);
//ignore this gmail_data stuff // undefined in this scope // checking to make sure it's a "new" unread msg
//if (gmail_data != msg_first.Date.ToString())
//{
// gmail_data = msg_first.Date.ToString();
XElement xmail = new XElement("gmail",
new XAttribute("count", ids.Length.ToString()),
new XAttribute("modified", msg_first.Date.ToString())
);
string name = "", address = "", from = "";
Regex reg_name = new Regex("\"[^\"]+");
Regex reg_address = new Regex("<[^>]+");
ActiveUp.Net.Mail.Message msg = null;
for (var i = 0; i < ids.Length; i++)
{
msg = inbox.Fetch.MessageObject(ids[i]);
from = msg.HeaderFields["from"];
name = reg_name.Match(from).Value.Replace("\"", "");
address = reg_address.Match(from).Value.Replace("<", "");
xmail.Add(new XElement("entry",
new XAttribute("id", msg.MessageId),
new XAttribute("modified", msg.Date.ToString()),
new XAttribute("name", name),
new XAttribute("address", address),
new XElement("subject", msg.Subject),
new XElement("body-text", msg.BodyText.TextStripped),
new XElement("body-html", msg.BodyHtml.Text)
));
//mark as unread
var flags = new FlagCollection();
flags.Add("Seen");
inbox.RemoveFlags(ids[i], flags);
}
File.WriteAllText("gmail.xml", xmail.ToString());
}
}
可能的代碼:
public void MarkAsUnread(List<string> messageIdList)
{
Mailbox inbox = Client.SelectMailbox("inbox");
int[] ids = inbox.Search("ALL");
int ListCount = messageIdList.Count;
int MarkedAsUnread = 0;
if (ids.Length > 0)
{
ActiveUp.Net.Mail.Message msg = null;
for (var i = 0; i < ids.Length; i++)
{
msg = inbox.Fetch.MessageObject(ids[i]);
// if messageId is on the list, mark as unread.
if (String.Join(",", messageIdList).Contains(msg.MessageId))
{
var flags = new FlagCollection { "Seen" };
inbox.RemoveFlagsSilent(i+1, flags);
MarkedAsUnread = MarkedAsUnread + 1;
}
// optimization
if (MarkedAsUnread == ListCount)
{
break;
}
}
}
}
*如果你真的不想得到所有,也許你可以使用類似的代碼按日期過濾:
var box = imap.SelectMailbox("inbox");
var ids = box.Search("OR (CC @cc.lieser-online.de) (HEADER Envelope-To @cc.lieser-online.de)");
