实体框架中有许多人无法获得相关数据

Question

尝试从多个表中获取集合而没有运气。 目前有3个表。我不确定如何到达每个作业的SkillPool_lookup.skillname。

我目前有。

 using(Entities dbCtx = new Entities())
       {
           this.JobList = dbCtx.Jobs.Where(x => x.JobStatusId == 1)
            .Include(x => x.JobStatus_Lookup)
            .Include(x => x.Budget_Lookup)
            .Include(x => x.JobCategories_Lookup)
            .Include(x => x.JobType_Lookup)
            .Include(x => x.Job_SubCategories_Lookup)
            .Include(x => x.TimeLine_Lookup)
            .Include(x => x.RequiredJobSkills)
            .OrderByDescending(x => x.DateCreated)
            .ToList();


        }

但是Requirejobskills.skillpool_lookup总是为空???卡住。请帮忙。
