C# Linq包括不工作

我有这个linq表达式

ActionPlan
    .Include(x => x.Goal)
    .Include(x => x.Responsibles)
    .Include(x => x.Goal.EducationalPlan)
    .AsNoTracking()
    .Where(x => x.State == State.Active && x.Goal.State == State.Active && x.Goal.EducationalPlan.State == State.Active)
    .Where(x => x.Responsibles.Any(r => r.PersonId == pes_id))
    .Distinct()
    .Select(x => x.Goal)
    .ToList();

教育计划的纳入不起作用，为什么？所有其他工作正常，

教育计划是一个对象而不是一个列表。

对于多个级别，您应该这样做：

ActionPlan
    .Include(x => x.Goal)
    .Include(x => x.Responsibles)
    .Include(x => x.Goal.Select(y => y.EducationalPlan))
    .AsNoTracking()
    .Where(x => x.State == State.Active && x.Goal.State == State.Active && x.Goal.EducationalPlan.State == State.Active)
    .Where(x => x.Responsibles.Any(r => r.PersonId == pes_id))
    .Distinct()
    .Select(x => x.Goal)
    .ToList();

或者试试这个：

ActionPlan
    .Include(x => x.Goal)
    .Include(x => x.Responsibles)
    .Include("Goal.EducationalPlan")
    .AsNoTracking()
    .Where(x => x.State == State.Active && x.Goal.State == State.Active && x.Goal.EducationalPlan.State == State.Active)
    .Where(x => x.Responsibles.Any(r => r.PersonId == pes_id))
    .Distinct()
    .Select(x => x.Goal)
    .ToList();

goal

是收藏吗？我觉得不错。你确定有与该目标相关联的教育计划吗？是什么让你认为

goal

是一个集合？这个.Include（“goal.EducationalPlan”）应该有效！
