Question

我在asp.net mvc中有一个表单HTML，我想将数据保存为db中的新行，我使用Mapper.Map作为viewmodel和domain本身。这是确切的错误：

“缺少类型映射配置或不支持的映射。\ r \ n \ r \ nMapping类型：\ r \ nCollateralViewModel - ＆gt; Collateral \ r \ nViewModels.CollateralViewModel - ＆gt; Domain.Entities.Collateral \ r \ n \ r \ n \ n目标路径：\ r \ nCollateral \ r \ n \ r \ nSource值：\ r \ nViewModels.CollateralViewModel“}

内部异常：null。

我的配置是：

Mapper.CreateMap<Collateral, CollateralViewModel>();

保存调用，然后保存从控制器创建。

 public CollateralViewModel Save(CollateralViewModel model, string username)
            {
                CollateralViewModel collateral = null;
                if (model.Id == 0)
                    collateral = CreateCollateral(model, username);
                else collateral = UpdateCollateral(model, username);

               return collateral;
            }

     private CollateralViewModel CreateCollateral(CollateralViewModel model, string username)
            {
                var newCollateral = ModelToDomain(model);

            }

    //this line throws an error 
     //Mapper.Map<CollateralViewModel, Collateral>(model);
    public Collateral ModelToDomain(CollateralViewModel model)
            {
                Collateral collateral = Mapper.Map<CollateralViewModel, Collateral>(model);
                return collateral;
            }

但它适用于调用此内容的UPDATE：

    public CollateralViewModel DomainToModel(Collateral collateral)
            {
                CollateralViewModel model = Mapper.Map<Collateral, CollateralViewModel>(collateral);

                return model;
            }

我也尝试过这样的实例化，但同样的错误：

public Collateral ModelToDomain(CollateralViewModel model)
        {
            Collateral collateral = new Collateral(); 
collateral  = Mapper.Map<CollateralViewModel, Collateral>(model);
            return collateral;
        }

我也尝试过这样做，对于不在域中的属性：

 Mapper.CreateMap<Collateral, CollateralViewModel>()
                .ForMember(x => x.AssetGroupTypes, opt => opt.Ignore())
                .ForMember(x => x.Client, opt => opt.Ignore())
                .ForMember(x => x.CollateralInstrumentTypes, opt => opt.Ignore())
                .ForMember(x => x.CollateralId, opt => opt.Ignore())
                .ForMember(x => x.Currencies, opt => opt.Ignore())
                .ForMember(x => x.RoundingMethods, opt => opt.Ignore());

有什么我错过的吗？我很擅长使用它。任何帮助？感谢
