Autofac 配置 - 如何将代码部分转换为 Autofac 配置

Question

我正在构建 Autofac 容器，如下所示

_container = ConfigureContainer(new ContainerBuilder()).Build();

我有 ConfigureContainer 方法 build/configure Autofac ContainerBuilder 如下

        private static ContainerBuilder ConfigureContainer(ContainerBuilder cb)
        {
            cb.RegisterModule(new QuartzAutofacFactoryModule());
            cb.RegisterModule(new QuartzAutofacJobsModule(Assembly.GetExecutingAssembly()));

            cb.Register(l => Logging.Logger.Instance()).As<ILogger>();

            var reader = new ConfigurationSettingsReader();
            cb.RegisterModule(reader);

            // How do I convert following lines to Autofac Config?

            cb.RegisterCollection<StandardTask>("IList<StandardTask>").As<IList<StandardTask>>();

            cb.RegisterType<HealthMonitoringMessageDispatcherTask>().Named<StandardTask>("HealthMonitoringTask1").MemberOf("IList<StandardTask>");
            cb.RegisterType<HealthMonitoringMessageDispatcherTask>().Named<StandardTask>("HealthMonitoringTask2").MemberOf("IList<StandardTask>");

            cb.RegisterType<PurgeMessageDispatcherTask>().Named<StandardTask>("PurgeTask1");
            cb.RegisterType<PurgeMessageDispatcherTask>().Named<StandardTask>("PurgeTask2");

            return cb;
        }

我有如下 Autofac 配置部分

<autofac>
    <components>
      <!--<component type="NAB.Custom.Logging.Logger, NAB.Custom.Logging" service="NAB.Logging.Core.ILogger, NAB.Logging" />-->
      <component type="NAB.Windows.ServicesConsole.Services.SchedulerService, NAB.Windows.ServicesConsole" service="NAB.Windows.ServicesConsole.Services.Core.ITopshelfService, NAB.Windows.ServicesConsole" />
      <component type="NAB.Windows.ServicesConsole.Jobs.HealthMonitoringMessageDispatcherJob, NAB.Windows.ServicesConsole" />
      <component type="NAB.Windows.ServicesConsole.Jobs.PurgeMessageDispatcherJob, NAB.Windows.ServicesConsole" />
    </components>
  </autofac>

它正确地解析了自定义配置部分中的配置组件，但是，我也想将以下注册从代码移动到自定义配置部分，在那里我找不到合适的解决方案...

            // How do I convert following lines to Autofac Config?

            cb.RegisterCollection<StandardTask>("IList<StandardTask>").As<IList<StandardTask>>();

            cb.RegisterType<HealthMonitoringMessageDispatcherTask>().Named<StandardTask>("HealthMonitoringTask1").MemberOf("IList<StandardTask>");
            cb.RegisterType<HealthMonitoringMessageDispatcherTask>().Named<StandardTask>("HealthMonitoringTask2").MemberOf("IList<StandardTask>");

            cb.RegisterType<PurgeMessageDispatcherTask>().Named<StandardTask>("PurgeTask1");
            cb.RegisterType<PurgeMessageDispatcherTask>().Named<StandardTask>("PurgeTask2");

有什么建议吗？小代码片段将非常有用。基本上我正在注册 named 集合，然后将组件注入集合，这是我注册的对象之一的构造函数参数。

Documentation on how configuration works in Autofac is here. Unless you're on the 4.0 beta, you're probably looking at the 3.x XML configuration style.

您了解了组件注册。要将 key/name 添加到注册中，只需添加该属性即可。

<component type="Service"
           service="IService"
           name="the-key-goes-here" />

没有 XML 命名集合的配置支持。如果您一直在使用它们并且不能仅移动到 IEnumerable<T> 那么最好将它们留在模块中并通过配置注册模块。

<modules>
  <module type="MyModule" />
</modules>
