如何在Microsoft Bot Framework中拥有多个选项对话框

Question

我正在为facebook messenger在azure bot框架中构建一个简单的自动响应机器人。

到目前为止，我有：

public async Task StartAsync(IDialogContext context)
    {
        await context.PostAsync("Welcome!");
        context.Wait(MessageReceivedAsync);
    }

    public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> argument)
    {
        var message = await argument;

        if (message.Text.StartsWith("REPORT"))           

              PromptDialog.Choice(
                  context, 
                  this.OnOptionSelected, 
                  new List<string>() { "Good Driving", "Bad Driving"}, 
                  "Report Driver for?", 
                  "Not a valid option", 3);


        }            
        else
        {               
            await context.PostAsync($"Thank you for messaging AutoConscience! We will get back to you shortly <br/> <br/>You can report drivers on the road by replying with REPORT followed by the license plate"
                +"(REPORT ABC 123)");
            context.Wait(MessageReceivedAsync);
        }
    }


    public async Task OnOptionSelected(IDialogContext context, IAwaitable<string> argument)
    {
        var confirm = await argument;
        if (confirm == "Good Driving")
        {
            //Having Trouble with the following
                  PromptDialog.Choice(context, 
                  this.OnOptionSelected, 
                  new List<string>() { "Used Signal", "Allowed Lane Merge", "Kept Intersection Open", "Followed Right of Way","Patient Driver","Defensive Driver","Nice Car"}, 
                  "Report Driver for?", 
                  "Not a valid option", 3);
            //await context.PostAsync("Good");
        }

我希望在第一个之后显示另一个多选对话框，但是在用户从第一个对话框中选择后，僵尸程序会失败。提前谢谢！
