如何将 Automapper 与 Autofac 结合使用

我已经升级到最新版本的 AutoMapper (9.0) 并将静态配置更改为：

public static IMapper RegisterAutoMapper()
{
    var config = new MapperConfiguration(cfg =>
    {
        cfg.CreateMap<MyModel MyDto>;
        //etc...
   });
  
   var mapper = config.CreateMapper();
   return mapper;
}

使用之前的静态 API，我曾经执行以下操作Global.asax:

protected void Application_Start()
{
    GlobalConfiguration.Configure(WebApiConfig.Register);
    AutoMapping.Map();
}

WebApiConfig.Register注册路线并且还Autofac

我如何向 Autofac 注册 AutoMapper，因为目前我在此类行上遇到编译器错误：

var myDto = Mapper.Map<MyModel>(model);

并且编译器错误：

非静态字段、方法或属性“Mapper.Map(object)”需要对象引用

这是我之前做的一个：

public class YourAutofacModule : Module
{
    protected override void Load(ContainerBuilder builder)
    {
        //Also register any custom type converter/value resolvers
        builder.RegisterType<CustomValueResolver>().AsSelf();
        builder.RegisterType<CustomTypeConverter>().AsSelf();

        builder.Register(context => new MapperConfiguration(cfg =>
        {
            cfg.CreateMap<MyModel MyDto>;
            //etc...
        })).AsSelf().SingleInstance();

        builder.Register(c =>
        {
            //This resolves a new context that can be used later.
            var context = c.Resolve<IComponentContext>();
            var config = context.Resolve<MapperConfiguration>();
            return config.CreateMapper(context.Resolve);
        })
        .As<IMapper>()
        .InstancePerLifetimeScope();
    }
}

在global.asax.cs中

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        var builder = new ContainerBuilder();

        builder.RegisterModule<MyAutofacModule>();
        // Register anything else needed

        var container = builder.Build();

        // MVC resolver
        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

        // API Resolver
        GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container);
    }
}

然后你需要做的就是注入IMapper
