导航属性中的另一个 class 未映射:AutoMapper

Another class within the Navigation Properties not getting mapped : AutoMapper

我正在尝试使用具有导航属性 (EmployeeLeave) 的 AutoMapper classes 进行映射,该属性具有另一个 class(Leave) 的实例。我能够映射导航 属性 但不能映射导航 属性

中的 class
namespace Project.Core.Entities
{
 public class ApplicationUser : IdentityUser<int>
    {
        public string Title { get; set; }
          [DisplayName("First Name")]
        [Required, MaxLength(50, ErrorMessage = "Name cannot exceed 50 characters")]
        public string FirstName { get; set; }

        [DisplayName("Middle Name")]
        public string MiddleName { get; set; }

        [DisplayName("Last Name")]
        [Required]
        public string LastName { get; set; }

        public EmployeePersonalDetails EmployeePersonalDetails { get; set; }
        public ICollection<EmployeeLeave> EmployeeLeaves { get; set; }
      }
}

第二个class是

namespace Project.Application.Models
{
 public class ApplicationUserModel 
    {
        public string Title { get; set; }
      [DisplayName("First Name")]
        [Required, MaxLength(50, ErrorMessage = "Name cannot exceed 50 characters")]
        public string FirstName { get; set; }

        [DisplayName("Middle Name")]
        public string MiddleName { get; set; }

        [DisplayName("Last Name")]
        [Required]
        public string LastName { get; set; }


         public EmployeePersonalDetailsModel EmployeePersonalDetailsModel { get; set; }
        public ICollection<EmployeeLeaveModel> EmployeeLeavesModel{ get; set;}
     }
}

还有一个class(Leave)是EmployeeLeave中的一个实例class

namespace Project.Core.Entities
{
   public class EmployeeLeave : Entity
    {
        public ApplicationUser Employee { get; set; }
        public int EmployeeId { get; set; }
        public Leave Leave { get; set; }
        public int LeaveId { get; set; }
        public string LeaveStatus { get; set; }
    }
}

这是映射到

namespace Project.Application.Models
{
   public class EmployeeLeaveModel : BaseModel
    {
        public ApplicationUserModel Employee { get; set; }
        public int EmployeeId { get; set; }
        public LeaveModel LeaveModel { get; set; }
        public int LeaveId { get; set; }
        public string LeaveStatus { get; set; }
    }
}

这就是我映射的方式classes

namespace Project.Application.Mapper
{
   public class EmployeeProfile : Profile
    {
        public EmployeeProfile()
        {
            CreateMap<Leave, LeaveModel>().ReverseMap();
            CreateMap<ApplicationUserModel, ApplicationUser>().ReverseMap()
                .ForMember(a =>a.EmployeeLeavesModel , b =>b.MapFrom( b => b.EmployeeLeaves));
            CreateMap<EmployeePersonalDetails, EmployeePersonalDetailsModel>().ReverseMap();
            CreateMap<EmployeeLeave, EmployeeLeaveModel>().ReverseMap();
           

        }
    }
}

这是计算员工年假的方法,其中 2 classes 正在映射

 public async Task<double> TotalAnnualLeaveTaken(int userId)
        {
            var employee = await _employeeLeaveRepository.GetEmployee(userId);

            var user = _mapper.Map<ApplicationUserModel>(employee);
    ///rest of the method

        }

在 TotalAnnualLeavetaken() 方法中,员工通过 _employeeLeaveRepository 从 ApplicationUser class 获取它的值,并且使用 'for member()' 映射导航 属性 EmployeeLeaves。我希望 EmployeeLeave class 的 Leave 也与 EmployeeLeaveModel 的 LeaveModel 映射。有没有办法映射它?

您从 EmployeeLeaveEmployeeLeaveModel 的映射不知道如何处理属性 EmployeeLeave.LeaveEmployeeLeaveModel.LeaveModel。你必须这样告诉他:

CreateMap<EmployeeLeave, EmployeeLeaveModel>()
    .ForMember(it => it.LeaveModel, it => it.MapFrom(it2 => it2.Leave));
