映射时如何逃避编写大量重复代码？

Question

我使用实体框架有一个数据访问层（DAL），并且我想使用自动应用程序与上层通信。我将不得不将数据传输对象（DTO）映射到实体，作为每种方法的第一个操作，处理我的输入，然后继续从实体到DTOS映射。您会如何跳过编写此代码？

例如，请参见此处：

//This is a common method in my DAL
public CarDTO getCarByOwnerAndCreditStatus(OwnerDTO ownerDto, CreditDto creditDto)
{
    //I want to automatize this code on all methods similar to this
    Mapper.CreateMap<OwnerDTO,Owner>();
    Mapper.CreateMap<CreditDTO,Credit>();
    Owner owner = Mapper.map(ownerDto);
    Owner credit = Mapper.map(creditDto)

    //... Some code processing the mapped DTOs

   //I want to automatize this code on all methods similar to this 

   Mapper.CreateMap<Car,CarDTO>();
   Car car = Mapper.map(ownedCar);
   return car;
}

我将使用代码生成生成重复代码。
