Question

我有一个提示有4个选项，最后一个选项是用户可以退出提示，我想实现一些代码，以便机器人退出提示

   PromptDialog.Choice(context, this.OnOptionSelected, new List<string>() { FlightsOption, HotelsOption, TrainOption, GobackOption }, "Sure..! Tell me what booking would like to make..?", "Not a valid option", 3);

在上面的图片中，我已经实现了退出选项，如果用户选择退出，则转到切换退出的情况。

我也尝试过context.quit但是它会抛出错误

private async Task OnOptionSelected(IDialogContext context, IAwaitable<string> result)
    {
        try
        {
            string optionSelected = await result;

            switch (optionSelected)
            {
                case FlightsOption:
                    context.Call(new FlightDialog(), this.ResumeAfterOptionDialog);
                    break;

                case HotelsOption:
                    context.Call(new HotelsDialog(), this.ResumeAfterOptionDialog);
                    break;
                case TrainOption:
                    context.Call(new TrainDialog(), this.ResumeAfterOptionDialog);
                    break;
                case GobackOption:
                    //want some code here to quit the form
                    break;


            }
        }

首先，这不是表格流程。这是提示。现在您可以执行类似操作，或者从堆栈中退出对话框，如此

try
        {
            string optionSelected = await result;

            switch (optionSelected)
            {
                case FlightsOption:
                    context.Call(new FlightDialog(), this.ResumeAfterOptionDialog);
                    break;

                case HotelsOption:
                    context.Call(new HotelsDialog(), this.ResumeAfterOptionDialog);
                    break;
                case TrainOption:
                    context.Call(new TrainDialog(), this.ResumeAfterOptionDialog);
                    break;
                case GobackOption:
                    context.Done<object>(null);
                    break;


            }
        }

或者，您可以告诉某事，然后在同一个对话框中等待其他消息，如

 try
    {
        string optionSelected = await result;

        switch (optionSelected)
        {
            case FlightsOption:
                context.Call(new FlightDialog(), this.ResumeAfterOptionDialog);
                break;

            case HotelsOption:
                context.Call(new HotelsDialog(), this.ResumeAfterOptionDialog);
                break;
            case TrainOption:
                context.Call(new TrainDialog(), this.ResumeAfterOptionDialog);
                break;
            case GobackOption:
            await context.PostAsync("Ok, you came back. Now tell something new.");
            context.Wait(MessageReceivedAsync);
            break;
        }
    }

下一条消息将在此处

public virtual async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
        {
            var message = await result;
            context.Wait(MessageReceivedAsync);
        }

从Microsoft Bot Framework中的PromptDialog.Choice流程取消或退出
