从 CardImage List 机器人框架中选择特定图像

Question

我目前正在构建一个能够构建英雄卡片动态轮播的机器人，但是我还没有找到很多示例来说明要在哪张卡片上使用哪个图像。

public async Task Styles(IDialogContext context, LuisResult result)
        {
            InfoClass IC = new InfoClass();
            int count = IC.BuildArray().Length;
            PolaroidObject[] glasses = IC.BuildArray();
            int x = 0;
            var reply = context.MakeMessage();
            reply.AttachmentLayout = AttachmentLayoutTypes.Carousel;
            //Storing Images into variables
            List<CardImage> images = new List<CardImage>();
            CardImage Ci1 = new CardImage("https://polaroideyewear.com/content/dam/products/brands/pld/2017/04/2003960807lm/high-res/2003960807lm_p00.jpg/_jcr_content/renditions/cq5dam.web.1280.1280.jpeg");
            CardImage Ci2 = new CardImage("https://polaroideyewear.com/content/dam/products/brands/pld/2017/01/20035406lbuc/high-res/20035406lbuc_p00.jpg/_jcr_content/renditions/cq5dam.web.1280.1280.jpeg");
            CardImage Ci3 = new CardImage("https://polaroideyewear.com/en/sunglasses/pld/2017/PLD-4049-S.html");
            CardImage Ci4 = new CardImage("https://polaroideyewear.com/en/sunglasses/pld/2017/PLD-4050-S.html");
            CardImage Ci5 = new CardImage("https://polaroideyewear.com/content/dam/products/brands/pld/2017/04/2003940010ex/high-res/2003940010ex_p00.jpg/_jcr_content/renditions/cq5dam.web.1280.1280.jpeg");
            CardImage Ci6 = new CardImage("https://polaroideyewear.com/content/dam/products/brands/pld/2017/04/2003960807lm/high-res/2003960807lm_p00.jpg/_jcr_content/renditions/cq5dam.web.1280.1280.jpeg");
            CardImage Ci7 = new CardImage("https://polaroideyewear.com/content/dam/products/brands/pld/2017/04/2003960807lm/high-res/2003960807lm_p00.jpg/_jcr_content/renditions/cq5dam.web.1280.1280.jpeg");
            images.Add(Ci1);
            images.Add(Ci2);
            images.Add(Ci3);
            images.Add(Ci4);
            images.Add(Ci5);
            images.Add(Ci6);
            images.Add(Ci7);
            for (int z = 1; z <= count; z++)
            {
                HeroCard hc = new HeroCard()
                {
                    Title = glasses[x].Shape,
                    Images = images
                };
                reply.Attachments.Add(hc.ToAttachment());
                x++;
            }
            await context.PostAsync(reply);
            context.Wait(MessageReceived);
        }

这是我目前的做法，虽然有效，但它只加载列表中的第一张图片。我正在寻找一种方法来使用类似于数组的方法，您可以在其中指定 "Images = images[z]".

另外，我不确定保存这些图像的最佳方式，我有一个包含图像的文件夹和一个 get/set class。我希望以与处理形状相同的方式调用它们，但是它抱怨并要求 List<CardImage> 而不是字符串。

您需要在每张卡片上附加一张图片，而不是整个列表 - 类似这样，假设 x 是索引：

HeroCard hc = new HeroCard()
{
    Title = glasses[x].Shape,
    Images = new List<CardImage> { images[x] }
};
