我是C＃的新手，我想做一个混合Luis服务和customvision的机器人。

我希望用户能够向机器人发送图像或文本。

我从microsoft bot框架“核心bot” *和图像处理bot **（* https://github.com/microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/13.core-bot，** https://github.com/mandardhikari/ImageProcessingBot）开始

目前，我确实有这段代码是在两个样本之间混合使用的

我正在获取这些日志。

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，对以上内容的任何见解将不胜感激！
