AutoMapper 实现DTO和领域Model之间的转换

首先需要在NuGet中引用AutoMapper的类库

声明：

若class类型参数一致则：

Mapper.Initialize(x => x.CreateMap<原始Class, 须赋值Class>()));

若扩展参数：

Mapper.Initialize(x => x.CreateMap<business_Labi_CourseEnrollOrder, business_Labi_CourseEnrollOrderDto>().ForMember(y=>y.OrderDetails,dto=>dto.MapFrom(s=>s.OrderDetails.Select(t=>new business_Labi_CourseEnrollOrderDto.OrderDetail

                {

                    ProductVersionID = t.ProductVersionID,

                    Qty = t.Qty,

                    SalePrice = t.SalePrice,

                }))));

 调用：

var info = Mapper.Map<business_Labi_CourseEnrollOrder, business_Labi_CourseEnrollOrderDto>(item);
