多次注册相同的接口 - Autofac

Question

我正在尝试注册一个具有不同配置的接口，如下所示：private static ContainerBuilder RegisterAzureStorage(this ContainerBuilder containerBuilder, IAzureStorageOptions azureStorageOptions)    {        containerBuilder.Register(c =>                new AzureStorageKeyValuePersistenceService(                    new AzureStorageKeyValuePersistenceConfig(                        azureStorageOptions.DctAzureBlobConnectionString,                        azureStorageOptions.DctAzureBlobContainerName)))            .As<IStreamableKeyValuePersistenceService>()            .Keyed<IStreamableKeyValuePersistenceService>(PersistenceStorageKeys.DctAzureStorage)            .SingleInstance();        containerBuilder.Register(c =>                new AzureStorageKeyValuePersistenceService(                    new AzureStorageKeyValuePersistenceConfig(                        azureStorageOptions.NcsAzureBlobConnectionString,                        azureStorageOptions.NcsAzureBlobContainerName)))            .As<IStreamableKeyValuePersistenceService>()            .Keyed<IStreamableKeyValuePersistenceService>(PersistenceStorageKeys.NcsAzureStorage)            .SingleInstance();        return containerBuilder;    }然后在我的构造函数中：public ReportingController(        [KeyFilter(PersistenceStorageKeys.DctAzureStorage)] IStreamableKeyValuePersistenceService dctStorage,        [KeyFilter(PersistenceStorageKeys.NcsAzureStorage)] IStreamableKeyValuePersistenceService ncsStorage)    {        _dctStorage = dctStorage;        _ncsStorage = ncsStorage;    }和用法：await _dctStorage.SaveAsync(........);await _ncsStorage.SaveAsync(........);但是，在执行时，它只会拾取最后一次注册并将两个对象保存到同一位置。我可以使用可枚举方法让它工作：public ReportingController(IEnumerable<IStreamableKeyValuePersistenceService> storage)    {        _storage = storage;    }然后对于可枚举的每个，但如果可能的话我更愿意使用键控方法。关于我所缺少的任何想法？

对于以后遇到这个问题的人，我错过了注册，在这种情况下，执行接口IReportingController需要注册WithAttributeFiltering()如下：

containerBuilder.RegisterType<ReportingController>().As<IReportingController>().WithAttributeFiltering();
