我一直在自定义botframework（https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/13.core-bot）的corebot示例

尝试使其工作后，我意识到所提供的示例未处理与Luis意图无关的用户答案。

例如，我希望机器人在用户说“ blabla”时提示其重复。

在主对话框的代码下面。当我说“ blabla”（很显然Luis无法识别）时，该机器人会停止并从头开始重新启动。

// Call LUIS and gather any potential booking details. (Note the TurnContext has the response to the prompt.)
            var luisResult = await _luisRecognizer.RecognizeAsync<FlightBooking>(stepContext.Context,cancellationToken);
            switch (luisResult.TopIntent().intent)
            {
                case FlightBooking.Intent.BookFlight:
                    await ShowWarningForUnsupportedCities(stepContext.Context,luisResult,cancellationToken);

                    // Initialize BookingDetails with any entities we may have found in the response.
                    var bookingDetails = new BookingDetails()
                    {
                        // Get destination and origin from the composite entities arrays.
                        Destination = luisResult.ToEntities.Airport,Origin = luisResult.FromEntities.Airport,TravelDate = luisResult.TravelDate,};

                    // Run the BookingDialog giving it whatever details we have from the LUIS call,it will fill out the remainder.
                    return await stepContext.BeginDialogAsync(nameof(BookingDialog),bookingDetails,cancellationToken);

                case FlightBooking.Intent.GetWeather:
                    // We haven't implemented the GetWeatherDialog so we just display a TODO message.
                    var getWeatherMessageText = "TODO: get weather flow here";
                    var getWeatherMessage = MessageFactory.Text(getWeatherMessageText,getWeatherMessageText,InputHints.IgnoringInput);
                    await stepContext.Context.SendactivityAsync(getWeatherMessage,cancellationToken);
                    break;

                default:
                    // Catch all for unhandled intents
                    var didntUnderstandMessageText = $"Sorry,I didn't get that. Please try asking in a different way (intent was {luisResult.TopIntent().intent})";
                    var didntUnderstandMessage = MessageFactory.Text(didntUnderstandMessageText,didntUnderstandMessageText,InputHints.IgnoringInput);
                    await stepContext.Context.SendactivityAsync(didntUnderstandMessage,cancellationToken);
                    break;
            }

            return await stepContext.NextAsync(null,cancellationToken);
        }

我有办法解决这些问题吗？ 这可能真的很有用，我可以将其他意图留在循环中。

编辑

基于@billoverton的回答，如果要在切换之前，我想添加此内容。

if (luisResult.TopIntent().score < 0.5) 
{ FlightBooking.Intent = FlightBooking.Intent.None; } 

但是它说FlightBooking.Intent是类型而不是变量。
