简单的注入器注册IMappingEngine(AutoMapper)

Question

之前我使用过Autofac,但现在我想尝试一下SimpleInjector.我的问题是,在我的方法中调用mappingEngine时,我收到以下错误:

缺少类型映射配置或不支持的映射.

映射类型:Something - > SomethingDto目标路径:IEnumerable`1 [0]

来源价值:

_mappingEngine.Map<IEnumerable<SomethingDto>>(IEnumerableOfSomething);

^-- doesn't work

Mapper.Map<IEnumerable<SomethingDto>>(IEnumerableOfSomething);

^-- works (That's not what I want)

Mapper.Map不是我想要的.我在这里注册Automapper:

用简单的注射器替换Ninject

container.Register<ITypeMapFactory, TypeMapFactory>();
container.RegisterAll<IObjectMapper>(
    MapperRegistry.AllMappers());
container.RegisterSingle<ConfigurationStore>();
container.Register<IConfiguration>(() => 
    container.GetInstance<ConfigurationStore>());
container.Register<IConfigurationProvider>(() => 
    container.GetInstance<ConfigurationStore>());
container.Register<IMappingEngine, MappingEngine>();

---

Mapper.Initialize(x =>
            {
                var profiles = container.GetAllInstances<Profile>();

                foreach (var profile in profiles)
                {
                    x.AddProfile(profile);
                }
            });

        Mapper.AssertConfigurationIsValid();

我的问题是,如何在SimpleInjector中注册IMappingEngine并正确添加我的个人资料？

提前致谢!

解决了!:-)

在启动MvcControllerFactory后,我注册了我的配置文件太晚了.我希望我的伪示例可以帮助您防止出现这样的错误.

// SimpleInjector
var container = new Container();

// AutoMapper registration
container.Register<ITypeMapFactory, TypeMapFactory>();
container.RegisterCollection(MapperRegistry.Mappers);
container.RegisterSingleton<ConfigurationStore>();
container.Register<IConfiguration>(container.GetInstance<ConfigurationStore>);
container.Register<IConfigurationProvider>(container.GetInstance<ConfigurationStore>);
container.RegisterSingleton(() => Mapper.Engine);

// AutoMapper Profiles registration
container.RegisterCollection<Profile>(new MappingAProfile(), 
                                      new MappingBProfile(), 
                                      new MappingCProfile());

// Adding AutoMapper profiles
Mapper.Initialize(x =>
    {
        var profiles = container.GetAllInstances<Profile>();

        foreach (var profile in profiles)
        {
            x.AddProfile(profile);
        }
    });

Mapper.AssertConfigurationIsValid();

container.Verify();

container.RegisterAsMvcControllerFactory();
