来自其他表的自动映射器ID

Question

我有学生班：

@observable comparsionMap = new Map(); // the map that stores the sub stores


 neededStores.forEach(Store => {
   this.comparsionMap.set(
     Store.name,
     new Store(this.draftDto, this.handleUpdateCommonDto)
   );
 }); // the way i create my sub stores

 @computed get stuff() {
   console.log(this.comparsionMap)
   return this.comparsionMap.get("StoreB");
 } // my computed

和班级：

public class StudentsDTO
{
    public int Id { get; set; }
    public string FullName { get; set; }
    public int? FkGraduates { get; set; }
    public int FkClass { get; set; }
    public int? FkClassNavigationFkTeacher { get; set; }
}

我希望学生班上 public partial class Classes { public Classes() { Students = new HashSet<Students>(); } public int Id { get; set; } public string Title { get; set; } public int? FkTeacher { get; set; } public Teachers FkTeacherNavigation { get; set; } public ICollection<Students> Students { get; set; } } 班 为此，我使用自动映射器来映射值，这是我的方法：

FkTeacher

但是，这行不通，我得到 CreateMap<Classes, StudentsDTO>().ForMember(dto => dto.FkClassNavigationFkTeacher, opt => opt.MapFrom(x => x.FkTeacher)); 的{​​{1}}

我怎么了？

我没有得到的是，如果我在get方法中写了null：

fkClassNavigationFkTeacher

它返回var classes = _classesService.GetAllClasses();有什么意义？
