C# 更改视图模型自动映射器的映射规则

我有一个模型

public class Product : BaseEntity
    {
        private string _name;

        public string Name
        {
            get { return _name; }
            private set{_name = value;}
        }

        public decimal Price { get; set; }
        public double Weight { get; set; }
        public double Width { get; set; }
        public double Height { get; set; }
        public double Depth { get; set; }
        public DateTime DateAdded { get; set; }
        ...
        public string GeneralInfo {get{//some get logic}...}
}

和视图模型：

public sealed class ProductDetailsModel
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public decimal Price { get; set; }
        public double Weight { get; set; }
        public double Width { get; set; }
        public double Height { get; set; }
        public double Depth { get; set; }
        ...
        public string GeneralInfo {get;set;}
}

和控制器：

public class ProductController : Controller
{
  ...

public ActionResult Details(int id)
        {
            var product = _productRepository.GetProduct(id);
            var productViewModel = Mapper.Map<ProductDetailsModel>(product);
            return View(productViewModel);
        }
  ...
}

一切正常，但这是错误和不合逻辑的，因为我有一个视图模型来表示产品细节，所以我想将此逻辑添加到视图模型中，但我的视图模型实例是由mapper创建的，产品视图模型没有构造函数来传递产品实例以获取其一般信息，因为，正如我所说，它不需要在构造函数中。如何将此“如果为空，则为常规信息”替换逻辑添加到映射器或视图模型中？

请尝试AfterMap

Automapper.CreateMap<Product,ProductDetailsModel>()
    .AfterMap((p,pm) => {  
       // now you have access to both objects, so you can do whatever you please
     });

Automapper.CreateMap（）
.AfterMap（（p，pm）=>{
//现在您可以访问这两个对象，因此您可以随心所欲
});

public class Product : BaseEntity
{
    ...
    public string GeneralInfo
        {
            get
            {
                var gInfo = getGeneralInfoFromBD();
                if (gInfo==null) 
                     gInfo = GenerateGeneralInfoFromProductProperties();
                return gInfo;
            }
            set { SetPropertyValue(ProductPropertyType.GeneralInfo, value); }
        }
}

Automapper.CreateMap<Product,ProductDetailsModel>()
    .AfterMap((p,pm) => {  
       // now you have access to both objects, so you can do whatever you please
     });
