在 Bot Framework c# 的表单方法后回复英雄卡

Question

我有一个对话框，我从中开始表单，我想在用户完成表单后显示英雄卡片。我正在使用下面的代码启动表单，并分配 after form 方法。

var startFormDialog = Chain.From(() => FormDialog.FromForm(StartForm.BuildForm, FormOptions.PromptInStart));    
context.Call<StartForm>(startFormDialog,AfterMenuForm);

//AfterMenuForm method implementation
private async Task AfterMenuForm(IDialogContext context, IAwaitable<StartForm> result)
{
    message = (Activity)context.MakeMessage();
    Activity replyToConversation = message.CreateReply("Should go to conversation, with a hero card");
     replyToConversation.Recipient = message.From;
     replyToConversation.Type = "message";
     replyToConversation.Attachments = new List<Attachment>();
     //List<CardImage> cardImages = new List<CardImage>();
     replyToConversation.AttachmentLayout = "carousel";
     List<CardAction> cardButtons = new List<CardAction>();
     CardAction plButton = new CardAction()
     {
         Value = "https://en.wikipedia.org/wiki/Pig_Latin",
         Type = "openUrl",
         Title = "WikiPedia Page"
     };
     cardButtons.Add(plButton);
     HeroCard plCard = new HeroCard()
     {
         Title = "I'm a hero card",
         Subtitle = "Pig Latin Wikipedia Page",
         //Images = cardImages,
                    Buttons = cardButtons
      };
      Attachment plAttachment = plCard.ToAttachment();
      replyToConversation.Attachments.Add(plAttachment);
      await context.PostAsync(replyToConversation);
}

问题是，为了能够向用户发送英雄卡片答案，我需要 activity 对象，而这在 AfterMenuForm 方法中不可用。有没有办法在此方法中显示 activity 对象？

Answer 1

您可以使用 IDialogContext 创建一个新的 IMessageActivity 并发送一个 HeroCard。

尝试context.MakeMessage();。收到消息后，您可以使用它来发送卡片。您不需要对该消息执行 CreateReply，这不是必需的。

此外，根据情况，您可能会访问原始内容 activity。在 context.Activity.

上可用

最后，我不确定你为什么要使用 Chain.From；你应该只使用：

var startFormDialog = FormDialog.FromForm(StartForm.BuildForm, FormOptions.PromptInStart));    
context.Call<StartForm>(startFormDialog,AfterMenuForm);
