Question

我正在替换静态AutoMapper API：

所以，在我有Profile之前：

public class DigitalResourceProfile : AutoMapper.Profile
{
    protected override void Configure()
    {
        AutoMapper.Mapper.CreateMap<DTO, Domain>();

        AutoMapper.Mapper.CreateMap<Domain, DTO>()
            .ForMember(dst => dst.Attachs, opts => opts.MapFrom(src => AutoMapper.Mapper.Map<List<AttachDomain>, List<AttachDTO>>(src.Attachs)))
            .ForMember(dst => dst.Timestamp, opts => opts.MapFrom(s => s.Timestamp.ToUniversalTime()));

        AutoMapper.Mapper.CreateMap<AttachDTO, AttachDomain>();

        AutoMapper.Mapper.CreateMap<AttachDomain, AttachDTO>()
            .ForMember(dst => dst.Timestamp, opts => opts.MapFrom(s => s.Timestamp.ToUniversalTime()));
    }
}

从现在开始，此个人资料类就像：

public class DigitalResourceProfile : AutoMapper.Profile
{
    protected override void Configure()
    {
        this.CreateMap<DTO, Domain>();

        this.CreateMap<Domain, DTO>()
>>>>>>>>>>>>>>>>>.ForMember(dst => dst.Attachs, opts => opts.MapFrom(src => AutoMapper.Mapper.Map<List<AttachDomain>, List<AttachDTO>>(src.Attachs)))
            .ForMember(dst => dst.Timestamp, opts => opts.MapFrom(s => s.Timestamp.ToUniversalTime()));

        this.CreateMap<AttachDTO, AttachDomain>();

        this.CreateMap<AttachDomain, AttachDTO>()
            .ForMember(dst => dst.Timestamp, opts => opts.MapFrom(s => s.Timestamp.ToUniversalTime()));
    }
}

但是，我不知道如何替换.ForMember(dst => dst.Attachs, opts => opts.MapFrom(src => AutoMapper.Mapper.Map<List<AttachDomain>, List<AttachDTO>>(src.Attachs)))。

有什么想法吗？

您可以通过Profile contructor传递映射引擎，而不是使用静态API。

您将在下面找到使用Unity的单元测试。

[TestClass]
public class UnitTest1
{
    public class TestA
    {
        public TestC valueA { get; set; }
    }
    public class TestB
    {
        public TestD valueB { get; set; }
    }

    public class TestC
    {
        public string value { get; set; }
    }
    public class TestD
    {
        public string value { get; set; }
    }

    private readonly IUnityContainer appContainer = new UnityContainer();

    public sealed class MappingConfiguration : Profile
    {
        private readonly IMappingEngine mappingEngine;

        // Inject mapping engine through constructor
        public MappingConfiguration(IMappingEngine mappingEngine)
            : base()
        {
            this.mappingEngine = mappingEngine;
        }

        protected override void Configure()
        {
            CreateMap<TestA, TestB>()
                .ForMember(dest => dest.valueB, o => o.ResolveUsing(src => 
                    this.mappingEngine.Mapper.Map<TestD>(src.valueA)));
            CreateMap<TestC, TestD>();
        }
    }

    [TestMethod]
    public void MappingTest()
    {
        // AutoMapper configuration
        var config = new MapperConfiguration(cfg =>
        {
            cfg.ConstructServicesUsing(type => appContainer.Resolve(type));
        });
        var mapper = config.CreateMapper();

        appContainer.RegisterInstance<IConfiguration>(config);
        appContainer.RegisterType<IMappingEngine, MappingEngine>(new InjectionConstructor(config, mapper));

        appContainer.Resolve<IConfiguration>().AddProfile(new MappingConfiguration(appContainer.Resolve<IMappingEngine>()));

        // Check config
        mapper.ConfigurationProvider.AssertConfigurationIsValid();

        var testIn = new TestA { valueA = new TestC { value = "This is a test" } };
        var result = mapper.Map<TestB>(testIn);
    }

}

替换静态AutoMapper API;替换Profile中的Map方法
