Question

我有两个班级：

public class Customer
{
    public string FirstName { get; set;  }

    public string LastName { get; set; }

    public int Quantity { get; set; }
};

public class Customer_
{
    public string FirstNam { get; set; }

    public string LastNam { get; set; }

    public int Quantity { get; set; }
}

两者之间的映射与Automapper库：

Customer[] data =  new Customer[3];

var config = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<Customer, Customer_>()
   .ForMember(dest => dest.FirstNam, opt => opt.MapFrom(src => src.FirstName))
   .ForMember(dest => dest.LastNam, opt => opt.MapFrom(src => src.LastName));

});

IMapper mapper = config.CreateMapper();
Customer_[] desti = mapper.Map<Customer[], Customer_[]>(data);

它有效，但是如何仅映射满足条件的数组数据元素？例如：仅映射具有Quantity > x

的元素

感谢的

通常我会在映射到AutoMapper之前执行此操作：

Customer_[] desti = mapper.Map<Customer[], Customer_[]>(
    data.Where(c => c.Quantity > 10).ToArray());

不要试图将这种智能放入AutoMapper中，这会让人感到困惑并导致错误。
