Answer 1

使用简单的Linq声明。

var episodes = shows.SelectMany(s=>s.Episodes.Where(e=>e.Seen.HasValue && !e.Seen.Value));

Answer 2

您可以使用LINQ执行此操作，如下所示：

using System.Linq;

IEnumerable<Episode> unseenEpisodes = (from show in shows
                        from episode in show.Episodes
                        where (episode.Seen.HasValue && episode.Seen.Value == false)
                        select episode);
