我有一个包含属性和模型的DTO,例如,一个学生可以有多个模块,而一个模块可以与一个以上学生相关联。属性可以很好地映射,但是模型不能映射。
public class GetStudentByIdMapping : Profile
{
public GetStudentByIdMapping()
{
CreateMap<Student,StudentDetails>();
CreateMap<Module, StudentDetails>()
.ForPath(dest => dest.StudentModules.ModuleName, opt => opt.MapFrom(m => m.ModuleName))
.ForPath(dest => dest.StudentModules.ModuleCode, opt => opt.MapFrom(m => m.ModuleCode))
.ForPath(dest => dest.StudentModules.Description, opt => opt.MapFrom(m => m.Description))
.ReverseMap();
}
}
public async Task<StudentDetails> GetStudent(int studentId)
{
var student = context.Student
.Where(s => s.StudentId == studentId)
.FirstOrDefault();
var module = await context.Order
.Include(m => m.Module)
.Where(o => o.StudentId == studentId)
.Select(m => m.Module).ToListAsync();
var studMap = Mapper.Map<StudentDetails>(student);
Mapper.Map<StudentDetails>(module);
return studMap;
}
这些是我想映射到StudentDetails ViewModel中的模型模型的ViewModels
public class StudentDetails
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public StudentModule StudentModules { get; set; }
}
public class StudentModule
{
public string ModuleName { get; set; }
public string ModuleCode { get; set; }
public string Description { get; set; }
}
这些是我由EF Core生成的实体
public partial class Student
{
public Student()
{
Order = new HashSet<Order>();
}
public int StudentId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public virtual ICollection<Order> Order { get; set; }
}
public partial class Module
{
public Module()
{
Order = new HashSet<Order>();
}
public int ModuleId { get; set; }
public int? LectureId { get; set; }
public string ModuleName { get; set; }
public string ModuleCode { get; set; }
public string Description { get; set; }
public string ModulePath { get; set; }
public virtual Lecture Lecture { get; set; }
public virtual ICollection<Order> Order { get; set; }
}
答案 0 :(得分:0)
您只需将创建的目的地传递给第二个地图通话:
映射时只需尝试以下代码:
var studMap = Mapper.Map<Student,StudentDetails>(student);
Mapper.Map<Module,StudentDetails>(module,studMap);
然后studMap
将收到所有映射字段的值。
