如何根据多个条件使用mailkit搜索imap收件箱？

Question

I want to search imap inbox with mailkit based on multiple condition like NotSeen & NotDeleted. I know the queries are receptively,if we do individual search query.

var uids = client.Inbox.Search(SearchQuery.NotSeen); 
var uids = client.Inbox.Search(SearchQuery.NotDeleted );   

but i need to put those two queries together & get all Uids based on the conditions. Any help would be appreciated.

Answer 1

You can combine search queries using the And() and/or Or():

var uids = client.Inbox.Search (SearchQuery.NotSeen.And (SearchQuery.NotDeleted));

or

var uids = client.Inbox.Search (SearchQuery.And (SearchQuery.NotSeen, SearchQuery.NotDeleted));

Answer 2

This snippet adds an conditional search condition after the main query has been set

var query = MailKit.Search.SearchQuery.FromContains("anyone@gmail.com")
                            .And(MailKit.Search.SearchQuery.SubjectContains("Your Subject"));

query = query .And(MailKit.Search.SearchQuery.DeliveredAfter(DateTime.Parse("2020-02-28")));

ok i found a way to manage it. Please suggest me if you have better way.

            var unread = client.Inbox.Search(SearchQuery.NotSeen);
            var Deleted = client.Inbox.Search(SearchQuery.Deleted);
            var Res  = unread.Except(Deleted).ToList();
