我有一个这样的视图模型:
public class CityModel
{
public int Id { get; set; }
[Required]
public int ProvinceId { get; set; }
[Required]
public string Caption { get; set; }
public string Description { get; set; }
}
和一个实体:
public class City : BaseEntity
{
public int ProvinceId { get; set; }
public string Caption { get; set; }
public string Description { get; set; }
public virtual Province Province { get; set; }
}
和一个 BaseEntity:
public abstract class BaseEntity
{
public int Id { get; set; }
public DateTime CreatedOn { set; get; }
public string CreatedBy { set; get; }
public DateTime ModifiedOn { set; get; }
public string ModifiedBy { set; get; }
}
我想使用 AutoMapper 在 Edit Action 中将 CityModel 类型的一个对象映射到 City 类型的对象上,
[HttpPost]
public ActionResult Edit(CityModel model)
{
if (ModelState.IsValid)
{
var entity = _cityRepository.GetCity(model.Id);
entity = model.ToEntity();
var operationStatus = _cityRepository.Edit(entity);
if (operationStatus.IsSuccess) operationStatus = _cityRepository.Save();
if (operationStatus.IsSuccess)
RedirectToAction("Index");
}
ViewBag.ProvinceId = new SelectList(_provinceRepository.Provinces, "Id", "Caption", model.ProvinceId);
return View(model);
}
ToEntity 是:
public static City ToEntity(this CityModel model)
{
return Mapper.DynamicMap<CityModel, City>(model);
}
最后创建从 CityModel 到 City 的地图使用此代码:
Mapper.CreateMap<CityModel, City>()
.ForMember(des => des.Caption, op => op.MapFrom(src => src.Caption.ToPersianContent()))
.ForMember(des => des.Description, op => op.MapFrom(src => src.Description.ToPersianContent()));
当我想从 CityModel 映射到 City 时,从数据库中获取 City。城市对象中的继承数据是正确的:
和 Mapping 之后,我想保留原始继承的映射和 automapper 忽略映射此基本属性,但 null 和默认值设置为此属性:
