C#BotFramework Prompt.Confirm显示太多尝试异常

问题描述

我最近正在使用Microsoft的botframework开发聊天机器人.我正在使用hint.confirm接受用户的是/否输入，但是当我编写基本的是/否时，它显示了太多尝试异常.我不希望我的机器人显示过多尝试异常，而是希望在内部处理它.这是我的代码.

I was recently developing a chatbot using Microsoft's botframework. I am using prompt.confirm to take user's yes/no input but it shows too many attempts exception when I write basic yes/no. I don't want my bot to display too many attempts exception instead I want to handle it internally. Here's my code.

[LuisIntent("None")]
public async Task NoneIntent(IDialogContext context, LuisResult result)
{
    try
    {
        PromptDialog.Confirm(context, NextQuestionAsync, QuestionPrompt, attempts: 1, promptStyle: PromptStyle.Auto);
    }
    catch (Exception ex)
    {
        await context.PostAsync("Something really bad happened.");
    }
}

public async Task NextQuestionAsync(IDialogContext context, IAwaitable<bool> result)
{
    try
    {
        if (await result)
        {
            await context.PostAsync($"Ok, alarm 0 disabled.");
            //context.Wait(NoneIntent);
        }
        else
        {
            await context.PostAsync("You Said No");
        }
    }
    catch (Exception e)
    {

    }
}

推荐答案

感谢ezequiel，我通过重写PromptOptions构造函数解决了此问题.我使用PromptDialog.Choice实现了它，但是我也可以通过确认来完成它.这就是我所做的

I resolved this issue by overriding the PromptOptions constructor, Thanks to ezequiel. I used PromptDialog.Choice to achieve it however I could also have done it with confirm. Here's what I did

    List<string> questions = new List<string>();
    questions.Add("Yes"); // Added yes option to prompt
    questions.Add("No"); // Added no option to prompt
    string QuestionPrompt = "Are you sure?";
    PromptOptions<string> options = new PromptOptions<string>(QuestionPrompt, "", "", questions, 1); // Overrided the PromptOptions Constructor.
   PromptDialog.Choice<string>(context, NextQuestionAsync, options);
