在我的Messages控制器中,我想检查传入消息的堆栈中是否有某个对话框,然后再将其分配给对话框,以便我可以抑制某些条件行为.我尝试按照 this answer解析IDialogStack,如下所示： @H_403_2@public async Task<HttpResponseMessage> Post([FromBody] Activity incomingMessage) { try { if (incomingMessage.Type == ActivityTypes.Message) { using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container,activity)) { var stack = scope.Resolve<IDialogStack>(); } ...

这是在我的Global.asax中注册的模块：

@H_403_2@private void RegisterBotModules() { var builder = new ContainerBuilder(); builder.RegisterModule(new DialogModule()); builder.RegisterModule(new ReflectionSurrogateModule()); builder.RegisterModule(new DialogModule_MakeRoot()); builder.RegisterModule<GlobalMessageHandler>(); builder.RegisterModule(new AzureModule(Assembly.GetExecutingAssembly())); var store = new TableBotDataStore(/*connection string*/); builder.Register(c => store) .Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore) .AsSelf() .SingleInstance(); builder.Register(c => new CachingBotDataStore(store,CachingBotDataStoreConsistencyPolicy.ETagBasedConsistency)) .As<IBotDataStore<BotData>>() .AsSelf() .InstancePerLifetimeScope(); builder.Update(Conversation.Container); var config = GlobalConfiguration.Configuration; config.DependencyResolver = new AutofacWebApiDependencyResolver(Conversation.Container); }

但是,我得到以下例外：

{“An error occurred during the activation of a particular registration. See the inner exception for details. Registration: Activator = IDialogTask (DelegateActivator),Services = [Microsoft.Bot.Builder.Dialogs.Internals.IDialogStack,Microsoft.Bot.Builder.Dialogs.Internals.IDialogTask],Lifetime = Autofac.Core.Lifetime.CurrentScopeLifetime,Sharing = Shared,Ownership = OwnedByLifetimeScope —> Object reference not set to an instance of an object. (See inner exception for details.)”

内部异常：

“Object reference not set to an instance of an object.”

链接答案中的建议是否已弃用？我缺少一些模块注册吗？我会很感激任何方向！
