使用imap协议Tcpclient将电子邮件标记为已读 [英] Mark email as read using imap protocol Tcpclient

问题描述

_imapSw.WriteLine("$ STATUS INBOX (unseen)");
_imapSw.WriteLine("$ SELECT INBOX");
_imapSw.Flush();

在收到看不见的电子邮件计数后，我想将电子邮件标记为已读。请告诉我命令将第一封电子邮件标记为已读。
`

After getting email count of unseen.I want to mark email as read. Please tell me command to mark first email as read. `

_imapSw.WriteLine（ $ FETCH + index +（body [header.fields（来自主题日期）]））；
_imapSw.WriteLine（ $ FETCH + index + body [text]）;`

_imapSw.WriteLine("$ FETCH " + index + " (body[header.fields (from subject date)])"); _imapSw.WriteLine("$ FETCH " + index + " body[text]");`

我可以获取电子邮件标头和正文，但这不是将电子邮件标记为已读。

i can fetch email header and body but this is not marking email as read.

推荐答案

选择收件箱时，您将获得第一个未读/未看到邮件的ID。

When selecting the inbox, you get the ID of the first unread/unseen mail.

* FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $Junk Junk $MDNSent $F
orwarded)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $Junk Jun
k $MDNSent $Forwarded \*)] Flags permitted.
* 8421 EXISTS
* 0 RECENT
* OK [UNSEEN 3395] First unseen.
* OK [UIDVALIDITY 47932578432] UIDs valid
* OK [UIDNEXT 46214] Predicted next UID
* OK [HIGHESTMODSEQ 1377] Highest

然后您可以使用store命令将其标记为已读：

Then you can use the store command to mark it as read:

_imapSw.WriteLine("$ STORE 3395 +flags \\seen");
_imapSw.Flush();
