botframework - 如何将提示值从主对话框传递给调度程序？

Question

`命名空间 Microsoft.BotBuilderSamples { 公共类 DispatchBot : ActivityHandler { 私有 ILogger _logger; 私有 IBotServices _botServices；

    public DispatchBot(IBotServices botServices, ILogger<DispatchBot> logger)
    {
        _logger = logger;
        _botServices = botServices;
    }

    protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
    {
        // First, we use the dispatch model to determine which cognitive service (LUIS or QnA) to use.
        var recognizerResult = await _botServices.Dispatch.RecognizeAsync(turnContext, cancellationToken);

        // Top intent tell us which cognitive service to use.
        var topIntent = recognizerResult.GetTopScoringIntent();

        // Next, we call the dispatcher with the top intent.
        await DispatchToTopIntentAsync(turnContext, topIntent.intent, recognizerResult, cancellationToken);

    }

`我有一个描述的场景：当用户打招呼时，机器人会显示自适应卡片（每张卡片上都有 Action.Submit）。----假设卡片为： 1. 订票 2. 需要帮助
3. 每当用户单击任何选项时取消，我都会得到相同的用户单击值。喜欢

1. 如果用户选择“需要帮助”。我得到相同的价值..

2. 然后我像任何问题（查询）一样从用户那里获得输入。

3. 然后此查询将转到调度程序的特定意图，但不会从调度程序转到意图并显示错误（对象引用未设置为对象的实例）

所以我该怎么做？

供参考，我已经通过此链接“如何检索用户在自适应卡中输入的 c# 代码以及如何在提交按钮单击时调用下一个意图”

它应该在用户输入后从调度程序机器人中获取价值。
