问题与C＃Microsoft Bot Hero卡回发功能

Question

我正在创建一个简单的电影票预订应用程序，我使用英雄卡选择电影，在选择电影时，将显示带有YES / NO选项的确认消息。 这是高级代码流 1.使用HeroCard选择电影的MovieDialog 2.确认对话框以“是/否”显示确认选项

问题： 我在ConfirmationDialog中有一个resume方法（OnOptionConfirmationSelected），它应该在选择了prompt选项后执行，但是在单击movie按钮后会立即调用此方法。你能检查代码并告诉我问题在哪里吗？

代码：

MovieDialog

[Serializable]
public class ConfirmationDialog : IDialog<object>
{
    public async Task StartAsync(IDialogContext context)
    {


        context.Wait(MessageReceivedAsync);

        //return Task.CompletedTask;
    }





    public async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
    {
        Activity activity = (Activity)context.Activity;


        this.ShowOptions(context);

        //Below is Test line
        //context.ConversationData.TryGetValue(ContextConstants.MovieDateKey, out szMovieDate);
        //await context.PostAsync("List of movies in " + Convert.ToString(activity.Text));
        //If Context Forward is there then ContextWait is not needed. 
        //context.Wait(MessageReceivedAsync);
    }

    private void ShowOptions(IDialogContext context)
    {
        string szMovieDate = "";
        string szMovieLanguage = "";
        string szMovieName = "";
        context.ConversationData.TryGetValue(ContextConstants.MovieDateKey, out szMovieDate);
        context.ConversationData.TryGetValue(ContextConstants.LanguageKey, out szMovieLanguage);
        context.ConversationData.TryGetValue(ContextConstants.MovieNameKey, out szMovieName);

        string szConfirmationMessage = "";
        szConfirmationMessage = String.Format("You have booked ticket for movie {0} for this date {1}", szMovieName, szMovieDate);
        PromptDialog.Choice(context, this.OnOptionConfirmationSelected, new List<string>() { "Yes", "No" }, szConfirmationMessage, "Not a valid option", 3);
        //context.Wait(this.MessageReceivedAsync);
    }

    private async Task OnOptionConfirmationSelected(IDialogContext context, IAwaitable<string> result)
    {
        Activity activity = (Activity)context.Activity;
        var optionSelected = activity.Text;

        if (optionSelected.ToUpper() == "YES" || optionSelected.ToUpper() == "NO")
        {
            //await context.PostAsync(Convert.ToString(optionSelected));
            context.Done(optionSelected);
        }
        else
        {
            context.Wait(this.MessageReceivedAsync);
        }
    }
}

ConfirmationDialog

=Sum(iif(Fields!Category.Value="Labor", Fields!ActualCost.Value, 0), "Dataset1")

问题是在MessageReceivedAsync MovieDialog方法中你在if / else子句之外做context.Wait(this.MessageReceivedAsync);，所以你在同一个对话框中等待您要将邮件转发到ConfirmationDialog。您应该在PostAync

之后的if中移动等待线
