ASP.NET 中的條件包含

Question

我想根據 API 中的給定參數添加條件包含。 我把它寫下來了，但似乎不起作用，並且沒有一個包含起作用

哇，很簡單，

    IIncludableQueryable<ProductEntity, object?> dbSet = _context.Set<ProductEntity>().Include(i => i.Media);

    if (dto.ShowCategories.IsTrue()) dbSet = dbSet.Include(i => i.Categories);
    if (dto.ShowComments.IsTrue())
        dbSet = dbSet.Include(i => i.Comments!.Where(x => x.ParentId == null))
            .ThenInclude(x => x.Children)!
            .ThenInclude(x => x.Media);
    if (dto.ShowLocation.IsTrue()) dbSet = dbSet.Include(i => i.Locations);
    if (dto.ShowForms.IsTrue()) dbSet = dbSet.Include(i => i.Forms);
    if (dto.ShowMedia.IsTrue()) dbSet = dbSet.Include(i => i.Media);
    if (dto.ShowReports.IsTrue()) dbSet = dbSet.Include(i => i.Reports);
    if (dto.ShowTeams.IsTrue()) dbSet = dbSet.Include(i => i.Teams)!.ThenInclude(x => x.User).ThenInclude(x => x.Media);
    if (dto.ShowVotes.IsTrue()) dbSet = dbSet.Include(i => i.Votes);
    if (dto.ShowVoteFields.IsTrue()) dbSet = dbSet.Include(i => i.VoteFields);
    if (dto.ShowCreator.IsTrue()) dbSet = dbSet.Include(i => i.User).ThenInclude(x => x!.Media);
