Question

I have the following issue - how to check is there are any element from int array mailListIds contains in MailLists in MailListId field. I think it could be something like the following :

Builders<Profile>.Filter.AnyIn(p => p.MailLists.Select(m => m.MailListId), mailListIds)

But that code cannot be serialized into query. How to implement it ?

我已经通过以下方式解决了这个问题：

 Builders<Profile>.Filter.Where(p => p.MailLists.Any(b => mailListIds.Contains(b.MailListId)))
