问题描述
我是Bot Framework的新手，如果遇到任何错误，如何解决?
I'm new to Bot Framework, if i made any mistake, how to correct it?
我的Bot用于航班预订的简单场景，机器人从用户那里获取输入，用于输入城市，城市，出发日期，返回日期.收到返回日期后，我必须验证给定日期是否大于出发日期.
A simple scenario of my Bot which is used for flight booking, bot gets input from user for from city, to city, departure date, return date. After receiving return date, i have to validate whether the given date is greater than departure date.
如何将值从StepContext传递到Promptvalidatorcontext?
How to pass values from StepContext to Promptvalidatorcontext?

推荐答案
您应该使用turnContext将信息从stepContext传递到hintContext.promptContext.context.turnState.=
You should use turnContext to pass information from stepContext to promptContext.promptContext.context.turnState. =
