Answer 1

int unreadEmailCount = 0;

        SearchFilter searchFilter = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false));

        ItemView view = new ItemView(999);

        FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, searchFilter, view);
        unreadEmailCount = findResults.Items.Count;
