Question

下图是我的QnA KB，在这里我只期待输出你好，我怎么能帮到你？但是，当我在模拟器中进行测试以及回答时，我会在下面看到小图像，如第一张图像突出显示的那样。

以下是我的以下代码：我是编码新手。请告知以下代码是否需要更改。

将小图片放到我的答案下面

如果您向用户发送如下所示的空 HeroCard ，则会将其呈现为空白图像。

我是编码新手。请告知以下代码是否需要进行任何更改。

在您的代码中，我们可以发现您将消息转发到 BasicQnAMakerDialog 以获取QnAMaker GA服务，因此我假设您使用的是QnAMaker GA服务并使用GA QnAMaker服务用于启动QnAMakerDialog以响应用户查询的凭据。您可以参考以下示例代码来修改项目。

[Serializable]
public class RootDialog : IDialog<object>
{
    public async Task StartAsync(IDialogContext context)
    {
        /* Wait until the first message is received from the conversation and call MessageReceviedAsync 
        *  to process that message. */
        context.Wait(this.MessageReceivedAsync);
    }

    private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
    {
        /* When MessageReceivedAsync is called, it's passed an IAwaitable<IMessageActivity>. To get the message,
            *  await the result. */
        var message = await result;
        // var qnaAuthKey = Utils.GetAppSetting("QnAAuthKey");
        var qnaAuthKey = ConfigurationManager.AppSettings["QnAAuthKey"];
        var qnaKBId = ConfigurationManager.AppSettings["QnAKnowledgebaseId"];
        var endpointHostName = ConfigurationManager.AppSettings["QnAEndpointHostName"];

        // QnA Subscription Key and KnowledgeBase Id null verification
        if (!string.IsNullOrEmpty(qnaAuthKey) && !string.IsNullOrEmpty(qnaKBId))
        {
            await context.Forward(new BasicQnAMakerDialog(), AfterAnswerAsync, message, CancellationToken.None);
        }
        else
        {
            await context.PostAsync("Please set QnAKnowledgebaseId, QnAAuthKey and QnAEndpointHostName (if applicable) in App Settings. Learn how to get them at https://aka.ms/qnaabssetup.");
        }

    }

    private async Task AfterAnswerAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
    {
        // wait for the next user message
        context.Wait(MessageReceivedAsync);
    }

        Activity reply = ((Activity)context.Activity).CreateReply();
        string[] qnaAnswerDate = answer.Split(';');
        int dataSize = qnaAnswerDate.Length;

        if (dataSize > 1 && dataSize <= 4)
        {
            var attachment = GetSelectedCard(answer);
            reply.Attachments.Add(attachment);

            await context.PostAsync(reply);
        }
        else
        {

        }
    }

    private async Task AfterBasicQnAMakeAnswerAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
