c# automapper 总是转换空对象

Question

automapper 总是转换 null 对象并且它不会抛出任何异常这里是我的模型和我使用的方法...当我在 ProductModel 模型中初始化 ProductDetailsModel 时我想要什么我也想在 Product 模型中初始化... ProductModel 中的 ProductDetailsModel 和 CategoryModel 这两个对象都没有在 Product

中初始化

 public class Product
{
    [Key]
    public int ID { get; set; }
    public int? IDCategory { get; set; }
    public string Name { get; set; }
    public string Price { get; set; }
    public int Quantity { get; set; }
    public List<Image> Images { get; set; }
    [ForeignKey("IDCategory")]
    public Category Category { get; set; }

    public virtual ProductDetails ProductDetails { get; set; } 

}


 public class ProductModel
{
    [Key]
    public int ID { get; set; }
    [Required(ErrorMessage ="حقل الزامي")]
    public int? IDCategory { get; set; }
    public string Name { get; set; }
    [Required(ErrorMessage = "حقل الزامي")]
    [RegularExpression("([1-9][0-9]*)", ErrorMessage = "يجب ادخال ارقام فقط")]
    public string Price { get; set; }
    [Required(ErrorMessage = "حقل الزامي")]
    [RegularExpression("([1-9][0-9]*)", ErrorMessage = "يجب ادخال ارقام فقط")]
    public string Quantity { get; set; }
    public List<ImageModel> Images { get; set; } = new List<ImageModel>();
    public CategoryModel CategoryModel { get; set; } = new CategoryModel();
    public ProductDetailsModel ProductModelDetails { get; set; } = new ProductDetailsModel();
}


 public class ProfileMapper : Profile
{
    public ProfileMapper()
    {
        CreateMap<ProductModel, Product>().ReverseMap();
        CreateMap<ImageModel, Image>().ReverseMap();
        CreateMap<CategoryModel, Category>().ReverseMap();
        CreateMap<ProductDetailsModel, ProductDetails>().ReverseMap();

        

    }
}


public async Task Add(ProductModel entity)
    {
        try
        {
            var theObject = mapper.Map<ProductModel, Product>(entity);
            await Db.Product.AddAsync(theObject);
            
        }
        catch (Exception e)
        {
            await jSRuntime.ToastrError(e.Message);

        }

    }

private async Task AddProductsForm()
{

    await UnitOfWork.ProductRepository.Add(new ProductModel {ProductModelDetails = new ProductDetailsModel { Details="gg"},Images = new List<ImageModel> { new ImageModel { ImageUrl = defaultImage } } });
    await UnitOfWork.Complete();
    ProductModels = (ICollection<ProductModel>)await UnitOfWork.ProductRepository.GetALL();


}

您的映射不包括名称更改。例如来自 Category => CategoryModel

CreateMap<Product, ProductModel>()
    .ForMember(dest => dest.CategoryModel, opt => opt.MapFrom(src => src.Category))
    .ReverseMap();
