如何反向映射在 Automapper C# 中显式映射的实体的多个成员？

Question

我正在开发一个 C# 应用程序，我需要在其中映射 2 个实体。所以，我定义创建地图如下：

CreateMap<Source, Destination>()
                .ForMember(dest => dest.FirstName, map => map.MapFrom(src => src.Name.First))                                                                                           
                .ForMember(dest => dest.LastName, map => map.MapFrom(src => src.Name.Last))
                .ForMember(dest => dest.SSN, map => map.MapFrom(src => src.SSN))
                .ForMember(dest => dest.HomePhoneNo, map => map.MapFrom(src => src.HomePhoneNumber()))
                .ForMember(dest => dest.Address, map => map.MapFrom(src => src.Address))
                .ForMember(dest => dest.MaritalStatus, map => map.MapFrom(src => (int)src.MaritalStatus))

现在，我想做ReverseMap，但是当我为每个成员添加.ReverseMap 时，在下一行成员中，src 和dest 被切换了。那么，有什么方法可以在一个地方为所有成员做ReverseMap吗？

只将一个 ReverseMap() 放在所有自定义映射的末尾。

这对我有用：

using AutoMapper;

class Program
{
    static void Main(string[] args)
    {            
        var configuration = new MapperConfiguration(cfg =>
        {
            cfg.CreateMap<X, Y>()
            .ForMember(dest => dest.Bar1, map => map.MapFrom(src => src.Foo1))
            .ForMember(dest => dest.Bar2, map => map.MapFrom(src => src.Foo2))
            .ReverseMap()                ;                
        });
        configuration.AssertConfigurationIsValid();
        var mapper = configuration.CreateMapper();
        var x1 = new X() {  Foo1 = "1", Foo2 = "2"};
        var mappedY = mapper.Map<Y>(x1);
        var againX = mapper.Map<X>(mappedY);
        Console.WriteLine($"{againX.Foo1} {againX.Foo2}");
    }
}

class X
{
    public string Foo1 { get; set; }
    public string Foo2 { get; set; }
}

class Y
{
    public string Bar1 { get; set; }
    public string Bar2 { get; set; }
}
