我在Hero卡中添加了6个按钮并尝试显示它们.它在团队和模拟器中工作正常但在Skype上不起作用.它只显示3个按钮.

 private List<CardAction> GetCardButton(List<string> opts)
    {
        List<CardAction> cardButtons = new List<CardAction>();
        int i = 1;
        foreach(string opt in opts)
        {
            CardAction plButton = new CardAction()
            {
                Title = opt,
                Type = "postBack",
                Text = i.ToString(),
                Value = i.ToString()
            };
            cardButtons.Add(plButton);
            i++;
        }

        return cardButtons;

    }
 //passing list of strings.
 List<CardAction> cardButtons = GetCardButton(cardOpts);

        HeroCard plCard = new HeroCard()
        {
            Title = "Try here",
            Text = "with:",
            Buttons = cardButtons

        };
        plAttachment = plCard.ToAttachment();

但在Skype中我只看到前3个按钮.有什么方法可以使卡可滚动或减少按钮大小？

解决方法:

如前面的答案所示,每个频道都有可以显示的内容,按钮数量,文本长度等限制.似乎您遇到了这个限制.您可以做的一件事是,如果有三个以上的按钮显示另一张卡并将它们显示在列表或轮播中.

这是一个被黑客攻击的代码示例：

using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace Bot_Application13.Dialogs
{
    [Serializable]
    public class RootDialog : IDialog<object>
    {

        public Task StartAsync(IDialogContext context)
        {
            context.Wait(MessageReceivedAsync);

            return Task.CompletedTask;
        }

        private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
        {
            List<Attachment> cards = new List<Attachment>();
            List<CardAction> buttons = new List<CardAction>();
            for (int i = 0; i < 10; i++)
            {
                CardAction ca = new CardAction()
                {
                    Title = i.ToString(),
                    Type = "postBack",
                    Text = i.ToString(),
                    Value = i.ToString()
                };
                buttons.Add(ca);
            }

            var reply = context.MakeMessage();
            GetCardsAttachments(buttons, cards);
            //reply.AttachmentLayout = AttachmentLayoutTypes.List;
            //or
            reply.AttachmentLayout = AttachmentLayoutTypes.Carousel;
            reply.Attachments = cards;

            await context.PostAsync(reply);

            context.Wait(this.MessageReceivedAsync);
        }

        private Attachment GetHeroCard(List<CardAction> buttons)
        {
            var heroCard = new HeroCard();
            //heroCard.Title = "Title";
            heroCard.Buttons = buttons;
            return heroCard.ToAttachment();  
        }

        private void GetCardsAttachments(List<CardAction> buttons, List<Attachment> cards)
        {
            if (buttons.Count <= 3)
            {
                cards.Add(GetHeroCard(buttons));
            }
            else
            {
                var temp = new List<CardAction>();
                for (int i = 0; i < buttons.Count; i++)
                {
                    if (i % 3 != 0)
                    {
                        temp.Add(buttons.ElementAt(i));
                    }
                    else
                    {
                        if (i != 0)
                        {
                            cards.Add(GetHeroCard(temp));
                        }

                        temp = new List<CardAction>();
                        temp.Add(buttons.ElementAt(i));
                    }

                }
                cards.Add(GetHeroCard(temp));
            }
        }
    }
}
