c# - FormFlow の「ヘルプ」コマンドと Scorables/GlobalMessage ハンドラの「ヘルプ」コマンド

Question

会話が FormFlow 内にあり、ユーザーが「ヘルプ」と入力すると、現時点では Scorables グローバル メッセージ ハンドラの「ヘルプ」が制御を引き継ぎます。FormFlows の「ヘルプ」コマンドはフォーム内にあり、Scorables の「ヘルプ」は他の会話にある場合にのみ使用したいと思います。これを達成する方法はありますか？

CancellationToken token)

     if (message != null) 
     { 
          var helpDialog = new HelpDialog(); 
          var interruption = helpDialog.Void<object, IMessageActivity>(); 
          this.task.Call(interruption, null); 
          await this.task.PollAsync(token); 
     } 
}

        var userHelpMessage = "You have reached Help Section.\n"

                               + "\n Your previous conversation is active 
         and you can return to prior dialog by typing 'Back' or 'Return'.";

        await context.PostAsync(userHelpMessage);

        context.Wait(this.MessageReceived);
    }

    private async Task MessageReceived(IDialogContext context, 
    IAwaitable<IMessageActivity> result)
    {
        var message = await result;

        var incomingMessage = message.Text.ToLowerInvariant();

        if ((incomingMessage != null) && (incomingMessage.Trim().Length > 0))
        {

            context.Fail(new Exception("Message was not a string or was an empty string."));
        }
    }
