[英]Luis + CustomVision in a single Microsoft Bot Framework
我是 C# 的新手,我想制作一個混合 Luis 服務和 customvision 的機器人。
我希望用戶能夠向機器人發送圖像或文本。
我從 microsoft bot 框架“core bot”* 和圖像處理 bot** 開始(* https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/13.core-bot,* * https://github.com/mandardhikari/ImageProcessingBot )
目前,我確實有這段代碼混合在兩個樣本之間

我正在獲取這些日志。
1>ImageProcessingBot.cs(78,41,78,46): error CS0136: A local or parameter named 'reply' cannot be declared in this scope because that name is used in an enclosing local scope to define a local or parameter
1>ImageProcessingBot.cs(72,33,72,67): error CS0163: Control cannot fall through from one case label ('case FlightBooking.Intent.Weather:') to another
我是 c# 的新手,因此對上述任何見解都將不勝感激!
這實質上是在重復@stuartd 在評論中所說的內容。 MessageFactory.Attachemnt
方法返回一個IMessageActivity
因此最好使用第二個變量而不是您的Activity reply
以避免強制轉換
case FlightBooking.Intent.Weather:
// 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 turnContext.SendActivityAsync(getWeatherMessage, cancellationToken);
var attachments = new List<Attachment>();
meesageReply = MessageFactory.Attachment(attachments); //new variable
messageReply.Attachments.Add(Cards.CreateAdaptiveCardAttachment());
break;
