AutoMapper - 在视图模型中映射子集合

使用AutoMapper库可以简化在应用程序中进行对象之间的映射操作。在某些情况下，我们需要将一个视图模型的子集合映射到另一个视图模型中。本文将介绍如何使用AutoMapper在视图模型中映射子集合，并提供一个案例代码来说明。

csharp
public class MappingProfile : Profile
{
    public MappingProfile()
    {
        CreateMap()
            .ForMember(dest => dest.ProductName, opt => opt.MapFrom(src => src.Name))
            .ForMember(dest => dest.ProductPrice, opt => opt.MapFrom(src => src.Price));
            
        CreateMap()
            .ForMember(dest => dest.OrderNumber, opt => opt.MapFrom(src => src.Number))
            .ForMember(dest => dest.Products, opt => opt.MapFrom(src => src.Products));
    }
}

csharp
public class OrderService
{
    private readonly IMapper _mapper;
    public OrderService(IMapper mapper)
    {
        _mapper = mapper;
    }
    public OrderDetailViewModel GetOrderDetail(OrderViewModel orderViewModel)
    {
        var orderDetailViewModel = _mapper.Map(orderViewModel);
        return orderDetailViewModel;
    }
}
