在C＃中将数据列表动态绑定到自适应卡列表

Question

我有要在bot框架v4中使用C＃动态绑定到自适应卡的数据类文件列表 我在下面尝试过：

mycsfile.cs

private asynch Task < DialogTurnResult > GetDynamicAdaptiveCard(WaterfallstepContext stepContext, CancellationToken cancellationToken) {
  //This is my json file where  am having all the data
  string json = File.ReadAllText("path of json file where I have list of data");
  JObject o = JObject.Parse(json);
  JArray a = (JArray) o["Info"];
  //converting json data to list of class
  IList < InfoListClass > list = a.ToObject < IList < InfoListClass >> ();
  //This is my json file where  am having adaptive card
  string json1 = File.ReadAllText("path of json file where I have adaptive card");
  JObject o1 = JObject.Parse(json1);
  JArray a1 = (JArray) o1["body"];
  foreach(var item in InfoListClass) {
   ((JObject) body[0])["text"] = item.name;
  }
  Attachment attachment = new Attachment() {
   ContentType = "application/vnd.microsoft.card.adaptive",
    Content = JsonConvert.DeserializeObject(json.ToString()),
  };
  return await stepContext.PrompAsynch(nameof(TextPrompt), new PromptOptions() {
    Prompt = new Activity {
      Type = ActivityTypes.Message,
       Attachments = new List < Attachment > {
        attachment
       },
       AttachmentLayout = AttachmentLayoutTypes.Carausel
     },
     RetryPrompt = MessageFactory.Text("Please"), cancellationToken);
  }

//我的自适应卡

{
    "type":"AdaptiveCard",
    "body":[
    {
    "type":"TextBlock",
    "size":"Medium",
    "weight":"Bolder"
    "text":"ABC"//This property I am trying to change with my class property in c#
    },
    {
    "type":"ColumnSet",
    "columns":[
    {
    "type":"Column",
    "items":[
    {
    "type":"Image",
    "style":"Person",
    "url":"boy picture path"// This one also I wanted to chnge with a other picture from c# by class property
    "size":"small"
    }
    ],
    "witdh":"auto"
    },
    {
    "type":"Column",
    "weight":"Bolder",
    "text":"Dr"//Thsi will also change from c#,
    "wrap":true
    }
    ]
    ]
    }

输出：我应该获得多张卡片，因为我的班级文件中有多个数据，但是我只获得了一张具有最后一个列表值的卡片。 请有人告诉我如何获得多张具有不同值的自适应卡吗？有人可以帮助我。 预先感谢。
