Botframework 无法从Json文件获取自适应卡值

我有以下Json文件

{
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "type": "AdaptiveCard",
  "version": "1.0",
  "body": [
    {
      "type": "TextBlock",
      "size": "Medium",
      "weight": "Bolder",
      "text": "Customer Information Form",
      "horizontalAlignment": "Center"
    },
    {
      "type": "Input.Text",
      "placeholder": "First Name",
      "style": "text",
      "maxLength": 0,
      "id": "SimpleVal",
      "color": "Red"
    },
    {
      "type": "Input.Text",
      "placeholder": "Last Name",
      "style": "Url",
      "maxLength": 0,
      "id": "UrlVal"
    },
    {
      "type": "Input.Text",
      "placeholder": "Company Name",
      "style": "text",
      "maxLength": 0,
      "id": "companyname",
      "color": "Red"
    },
    {
      "type": "Input.Text",
      "placeholder": "Email",
      "style": "Email",
      "maxLength": 0,
      "id": "EmailVal"
    },
    {
      "type": "Input.ChoiceSet",
      "placeholder": "Country",
      "id": "CompactSelectVal",
      "value": "1",
      "choices": [
        {
          "title": "Country",
          "value": "1"
        },
        {
          "title": "United States",
          "value": "2"
        },
        {
          "title": "Algeria",
          "value": "3"
        }
      ]
    },
    {
      "type": "Input.Text",
      "placeholder": "Phone Number",
      "style": "Tel",
      "maxLength": 0,
      "id": "TelVal"
    }




  ],
  "actions": [
    {
      "type": "Action.Submit",
      "title": "Submit",
      "data": {
        "id": "1234567890"
      }
    }
  ]
}

这是我的机器人输入表单：

当我尝试从turnContext检索值时，得到的值为空。请参阅下面的代码：

messageActivityAsync上的受保护覆盖异步任务（iTurContext turnContext，CancellationToken CancellationToken）
{
随机r=新随机（）；
var cardAttachment=CreateAdaptiveCardAttachment（_cards[r.Next（_cards.Length）]）；
Wait turnContext.SendActivityAsync（MessageFactory.Attachment（cardAttachment），cancellationToken）；
Wait turnContext.SendActivityAsync（MessageFactory.Text（“您的请求已提交，谢谢”），cancellationToken）；
}

我想我应该从turnContext活动中获得价值。但它看起来是空的。

请尝试下面的代码，从自适应卡中获取价值：

//Captature sumitted value
var txt = turnContext.Activity.Text;
dynamic val = turnContext.Activity.Value;

希望有帮助

你的意思是我应该在MessageActivityAsync的这个方法中这样做吗？是的。在OnMessageActivitySync中插入代码以获取自适应卡值
