如何解析自适应卡片中的提交操作值？我知道在附近但无法解决它。如果我手动输入文本，我会前进到瀑布模型中的新对话框

卡片.json

{  
    "type": "AdaptiveCard",
  "body": [
    {
      "type": "TextBlock",
      "id": "textBlock",
      "text": "CREATE AN INCIDENT. "
    },
    {
      "type": "Input.Text",
      "id": "username",
      "placeholder": "Enter your email address"

    },
    {
      "type": "Input.Text",
      "id": "shortdescription",
      "placeholder": "Enter a short description"

    },
    {
      "type": "Input.Number",
      "id": "phonenumber",
      "placeholder": "Enter your phonenumber"

    }

  ],  
    "actions": [  
        {  
            "type": "Action.Submit",  
            "id": "submit",  
            "title": "Submit",  
            "data":{  
                        "action": "mychoices"  

            }  
        }  
    ],  
    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",  
    "version": "1.0"  
}

RequestDialog.cs

var askforSelectionSteps = new WaterfallStep[]
            {
                askForSelection,
                askForSelectionResult,
                CreateTicketFor_InstallSoftware
            };



public async Task<DialogTurnResult> askForSelection(WaterfallStepContext sc, CancellationToken cancellationToken)
        {
            _state = new GenericRequestState();
            await _accessor.SetAsync(sc.Context, _state);
            //return await sc.PromptAsync(choiceprompt, new PromptOptions()
            //{
            //    Prompt = MessageFactory.Text("Can you please let me know if the request is for you or someone else?"),
            //    Choices = new List<Choice> { new Choice("MySelf"), new Choice("Someone Else") },
            //    RetryPrompt = MessageFactory.Text("Please enter MySelf or Someone Else."),
            //});
            return await sc.PromptAsync(TextPrompt, new PromptOptions()
            {
                Prompt = CardHelper.GenericRequestIncidentChoices(sc, cancellationToken),
            });
        }
        public async Task<DialogTurnResult> askForSelectionResult(WaterfallStepContext sc, CancellationToken cancellationToken)
        {
            var isSuccess = sc.Result.ToString().ToLower();
            if (isSuccess == "incident" || isSuccess == "inc")
            {
                //return await sc.BeginDialogAsync(GenericRequestationStep_OneId);
                return await sc.PromptAsync(TextPrompt, new PromptOptions()
                {
                    Prompt = CardHelper.GenericCreateIncident(sc, cancellationToken),
                });


            }}

我查看了一些示例和 stackoverflow 本身，但无法将提交操作传递回对话框。任何帮助将不胜感激！

【解决方案1】：

protected override async Task OnEventAsync(DialogContext dc, CancellationToken cancellationToken = default(CancellationToken))
    {
        var value = dc.Context.Activity.Value;

        if (value.GetType() == typeof(JObject))
        {
            var result = await dc.ContinueDialogAsync();
            return;
        }
    }

你有没有像上面那样在 OnEventAsync 中编写 JObject 处理？

【解决方案2】：

想知道如何处理JToken？如果是这样，请参阅下面的代码。

                var token = JToken.Parse(turnContext.Activity.ChannelData.ToString());
                if (token["postBack"].Value<bool>())
                {
                    JToken commandToken = JToken.Parse(turnContext.Activity.Value.ToString());
                    var data = commandToken["Your_Data_ID"].Value<Your_Data_Type>();
                }

“Your_Data_ID”是电话号码、简短描述等... Your_Data_Type 是 int、string 等...
