Answer 1

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

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

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