使用 Automapper 将加入的域模型映射到视图模型

Question

在我的业务逻辑中 class 我加入了两个数据模型并作为 IEnumerable 返回到控制器。我需要使用 automapper 将这些集合映射到列表。但它没有按预期工作。

逻辑class

 public IEnumerable<object> GetPurchaseOrderDetailsByPersonId(long personId)
    {
        var purchaseOrderDetails = from pom in _unitOfWork.DbSet<PurchaseOrderMain>()
                                   join rep in _unitOfWork.DbSet<RepresentativeMaster>() on pom.REPM_ID equals rep.REPM_ID
                                   where pom.REPM_ID == personId
                                   select new { pom.RM_ID,pom.OrderNo,pom.OrderAmount,pom.OrderDate ,rep.RepName };

        return purchaseOrderDetails;
    }

控制器

public ActionResult Index()
    {
        List<object> purchaseOrder = _CLS_PurchaseOrder_BLL.GetPurchaseOrderDetailsByPersonId(PersonId).ToList();

        return View(purchaseOrder.ToEntity<OMOS.Models.PurchaseOrderDetails>());
    }

ToEntity() 扩展 class

  public static List<TDestination> ToEntity<TDestination>(this List<object> OBJSource)
    {
        AutoMapper.Mapper.CreateMap<object, TDestination>();
        List<TDestination> destination = new List<TDestination>();//Handling the null destination
        foreach (object source in OBJSource)
        {
            destination.Add(AutoMapper.Mapper.Map<object, TDestination>(source));
        }
        return destination;
    }

但映射结果与预期不符。

像这样更改您的代码。

public static List<TDestination> ToEntity<TDestination>(this List<object> OBJSource)
    {
        List<TDestination> destination = new List<TDestination>();//Handling the null destination

        foreach (object source in OBJSource)
            destination.Add(AutoMapper.Mapper.DynamicMap<TDestination>(source));

        return destination;
    }

使用 Automapper 将加入的域模型映射到视图模型
