c# - 在 Entity Framework 中订购包含的实体的最佳方式？

Question

订购评论实体的最佳实践是什么？

 public async Task<IList<Post>> GetPosts() {
             var posts = _context.Posts
            .Include(u => u.User)
            .ThenInclude(p => p.Photos)
            .Include(c => c.Comments)   <---- THIS      
            .OrderByDescending(p => p.Created)
            .ToListAsync();

            return await posts;
        }

Answer 1

在返回帖子之前，您可以订购附加到每个帖子的评论:

var posts = await _context.Posts
                          .Include(u => u.User)
                          .ThenInclude(p => p.Photos)
                          .Include(c => c.Comments)         
                          .OrderByDescending(p => p.Created)
                          .ToListAsync();

foreach(var post in posts)
{
    post.Comments = post.Comments
                        .OrderBy(comment => comment.DateCreated)
                        .ToList();
} 

return posts;

我根据名为 DateCreated 的属性进行了上述排序。您必须将其更改为注释对象属性，您希望以此为基础进行排序。
