Question

我必须创建一个具有名称城市且每个城市都有不同假日列表的自适应卡。我必须在下拉列表中显示城市名称，在选择每个城市时，我必须显示包含假日列表的子卡。

我开发了以下代码：

private async Task<DialogTurnResult> ShowCard(WaterfallStepContext stepContext, CancellationToken cancellationToken)
{
    List<string> city = new List<string>() { "Delhi", "Bangalore", "Mumbai" };
    List<string> date = new List<string>() { "1-Jan", "26-Jan", "15-Aug" };
    List<string> des = new List<string>() { "New Year", "Republic Day", "Independence Day" };

    List<string> date1 = new List<string>() { "1-Jan", "26-Jan", "15-Aug", "25-Dec" };
    List<string> des1 = new List<string>() { "New Year", "Republic Day", "Independence Day", "Christmas Day" };

    List<string> date2 = new List<string>() { "1-Jan", "25-Dec" };
    List<string> des2 = new List<string>() { "New Year", "Christmas Day" };

    List<AdaptiveCard> cards = new List<AdaptiveCard>();
    cards.Add(HolidayListAdaptiveCard(date, des));
    cards.Add(HolidayListAdaptiveCard(date1, des1));
    cards.Add(HolidayListAdaptiveCard(date2, des2));

    var mainCard = new AdaptiveCard(new AdaptiveSchemaVersion(1, 0));
    var column3 = new AdaptiveColumn();
    column3.Items.Add(new AdaptiveTextBlock() { Text = "Holiday City", Weight = AdaptiveTextWeight.Bolder });
    var columnSet1 = new AdaptiveColumnSet();
    columnSet1.Columns.Add(column3);
    var container1 = new AdaptiveContainer();
    container1.Style = AdaptiveContainerStyle.Emphasis;
    container1.Items.Add(columnSet1);
    mainCard.Body.Add(container1);

    List<AdaptiveShowCardAction> adaptiveShowCardActions = new List<AdaptiveShowCardAction>();
    for (int i = 0; i < city.Count; i++)
    {
        mainCard.Actions.Add(new AdaptiveShowCardAction() { Title = city[i], Card = cards[i] });
    }

    var attachment = new Attachment
    {
        ContentType = AdaptiveCard.ContentType,
        Content = mainCard
    };
    var reply = MessageFactory.Attachment(attachment);
    await stepContext.Context.SendActivityAsync(reply);
    return new DialogTurnResult(DialogTurnStatus.Waiting);
}

private AdaptiveCard HolidayListAdaptiveCard(List<string> date, List<string> description)
{
    var card = new AdaptiveCard(new AdaptiveSchemaVersion(1, 0));
    List<AdaptiveColumn> columns = new List<AdaptiveColumn>();
    var column = new AdaptiveColumn();
    var column1 = new AdaptiveColumn();
    var column2 = new AdaptiveColumn();

    var textBlock = new AdaptiveTextBlock();
    textBlock.Text = "Sr. No";
    textBlock.Weight = AdaptiveTextWeight.Bolder;
    textBlock.Size = AdaptiveTextSize.Large;
    textBlock.Color = AdaptiveTextColor.Accent;
    column.Items.Add(textBlock);

    var textBlock1 = new AdaptiveTextBlock();
    textBlock1.Text = "Date";
    textBlock1.Weight = AdaptiveTextWeight.Bolder;
    textBlock1.Size = AdaptiveTextSize.Large;
    textBlock1.Color = AdaptiveTextColor.Good;
    column1.Items.Add(textBlock1);

    var textBlock2 = new AdaptiveTextBlock();
    textBlock2.Text = "Description";
    textBlock2.Weight = AdaptiveTextWeight.Bolder;
    textBlock2.Size = AdaptiveTextSize.Large;
    textBlock2.Color = AdaptiveTextColor.Dark;
    column2.Items.Add(textBlock2);

    for (int i = 0; i < date.Count; i++)
    {
        column.Items.Add(new AdaptiveTextBlock() { Text = (i + 1).ToString() });
        column1.Items.Add(new AdaptiveTextBlock() { Text = date[i] });
        column2.Items.Add(new AdaptiveTextBlock() { Text = description[i] });
    }

    var columnSet = new AdaptiveColumnSet();
    columnSet.Columns.Add(column);
    columnSet.Columns.Add(column1);
    columnSet.Columns.Add(column2);
    var container = new AdaptiveContainer();
    container.Style = AdaptiveContainerStyle.Emphasis;
    container.Items.Add(columnSet);
    card.Body.Add(container);
    return card;
}

O / P：

问题：城市名称作为单独的按钮显示，但我需要下拉列表中的城市名称。

您可以通过使用Input.ChoiceSet元素并将style设置为"compact"在Adaptive Card中创建一个下拉菜单。请注意，紧凑样式是Teams中的默认样式。

仅当使用Web Chat时，才能扩展Adaptive Card功能，这样您将无法响应此下拉列表中的事件，并且在用户填写卡片时将无法对其进行修改。您需要让用户选择一个城市，然后单击“提交”按钮。尽管Teams确实允许消息更新，因此您可以响应提交操作来更新卡，但仅发送带有假日列表的全新卡可能会更好，更容易。

自适应卡：在下拉菜单中动态显示卡，单击自适应卡：Bot Builder
