부모 클래스에서 자식 클래스 속성 가져 오기

데이터베이스 우선 접근 방식으로 응용 프로그램에 두 개의 컨트롤러가 있습니다.

SampCutReqMaster.CS

public partial class SampCutReqMaster
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public SampCutReqMaster()
        {
            this.SamCutAssignmentMasters = new HashSet<SamCutAssignmentMaster>();
        }

        public decimal SampCutreqID { get; set; }
        public Nullable<decimal> BuyerID { get; set; }
        public Nullable<decimal> PatternRefID { get; set; }
        public Nullable<decimal> PatternStyleID { get; set; }
        public Nullable<decimal> SampleTypeID { get; set; }


        public virtual BuyerMaster BuyerMaster { get; set; }
        public virtual PatternStyle PatternStyle { get; set; }
        public virtual PatterRefMaster PatterRefMaster { get; set; }
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<SamCutAssignmentMaster> SamCutAssignmentMasters { get; set; }
        public virtual SampleType SampleType { get; set; }
    }

그리고 다음은

SamCutAssignmentMaster

 public partial class SamCutAssignmentMaster
    {
        public decimal CutAssignID { get; set; }
        public decimal SampCutreqID { get; set; }
        public System.DateTime ReceivedDate { get; set; }
        public string ReceivedBy { get; set; }
        public Nullable<decimal> PatternMasterID { get; set; }                 

        public virtual PatternMaster PatternMaster { get; set; }
        public virtual SampCutReqMaster SampCutReqMaster { get; set; }
    }

SampCutReqMaster에 대한 인덱스보기가있는 컨트롤러를 만들었습니다.

public class SampCutReqMastersController : Controller
    {
        private ArtEntities db = new ArtEntities();
    // GET: SampCutReqMasters
    public ActionResult Index()
        {
            var sampCutReqMasters = db.SampCutReqMasters.Include(s => s.BuyerMaster).Include(s => s.PatternStyle).Include(s => s.PatterRefMaster).Include(s => s.SampleType).Include(s=>s.SamCutAssignmentMasters);

            var sampCutReqMasterssort = sampCutReqMasters.ToList().OrderByDescending(a => a.AddedDate);
            return View(sampCutReqMasterssort.ToList());
        }
}

SamCutReqMaster (상위)의 관점에서 SamcutAssignmentMaster (하위 클래스)의 "receivedBy"를 얻고 싶습니다. 그러나 SamCutReqMaster (FK는 SamCutReqID)와 관련된 SamcutAssignmentMaster에 데이터가 없을 수 있습니다.

아래 색인보기에서 SamcutAssignmentMaster.receivedBy에 액세스해야합니다.

   @model IEnumerable<WebArtSampler.Models.SampCutReqMaster>

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
