相关疑难解决方法(0)

我在.NET Core 1.1.0,EF Core 1.1.0,VS 2015上.

我正在编写一个帖子/评论系统,我需要一个函数来加载评论及其所有子项及其相关属性.这是我的课程的简化版本:

public class Comment
{
    public long Id { get; set; }

    public string Content { get; set; }

    public User User { get; set; }

    public ICollection<Comment> Replies { get; set; }
}

public class User
{
    public long Id { get; set; }

    public string Name { get; set; }

    public Avatar Avatar { get; set; }
}

public class Avatar
{
    public string Url { get; set; }
}

任何给定的评论都可以有任意数量的回复:

-PARENT …

有谁看到我做错了什么？
ProjectActivityTasks有UnitOfMeasureId和ProjectActivityTaskTypeId.随着它的编写方式,它认为这样UnitOfMeasure做ProjectActivityTaskType.它示数出来就ThenInclude对UnitOfMeasure他说

ProjectActivityTaskType不包含UnitOfMeasure的定义

哪个是对的.UnitOfMeasure去ProjectActivityTasks.

我正在引用此页面但它似乎没有这样工作:https://docs.microsoft.com/en-us/ef/core/querying/related-data

var qry = await _projectActivityRepository.GetAll()
.Include(x => x.ProjectActivityVehicles)
  .ThenInclude(x => x.Vehicle)
.Include(x => x.ProjectActivityTasks)
  .ThenInclude(x => x.ProjectActivityTaskType)
  .ThenInclude(x => x.UnitOfMeasure)
.Where(x => x.Id == Id && x.TenantId == (int)AbpSession.TenantId)
.FirstOrDefaultAsync();
