C# 如何在MessageController.cs Post方法中使用PromptDialog.Confirm（）

我想在聊天窗口中用是非选项提示问题

public class MessagesController : ApiController
{
    public virtual async Task<HttpResponseMessage> Post([FromBody] Activity activity)
    {
        ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
        Activity reply;

        if (activity != null)
        {
            // check if activity is of type message
            if (activity.Type == ActivityTypes.Message)
            {
                await GetEntityFromLUIS(activity);
            }
            else if (activity.Type == ActivityTypes.ConversationUpdate)
            {
                    constructResponse = "Hi";
                    reply = activity.CreateReply($"{constructResponse}");
                    await connector.Conversations.ReplyToActivityAsync(reply); //After this we need Prompt question with Yes r No
            }
        }
        else
        {
            connector = new ConnectorClient(new Uri(activity.ServiceUrl));

            HandleSystemMessage(activity);
        }

        return new HttpResponseMessage(System.Net.HttpStatusCode.Accepted);
    }
}

您可以使用PromptDialog。这样确认

PromptDialog.Confirm(context, Confirmed,"Have question");

确认（）在用户回答后发生

public async Task Confirmed(IDialogContext context, IAwaitable<bool> argument)
    {
        bool isCorrect = await argument;
        if (isCorrect)
        { }
        else
        { }
    }

已确认公共异步任务（IDialogContext上下文，IAwaitable参数）
{
bool isCorrect=等待参数；
如果（不正确）
{ }
其他的
{ }
}

我需要在MessageController.cs中声明这个已确认的函数，或者需要创建任何其他类。我确实在同一个MessageController.cs中声明了，但是bot没有响应，即使它没有显示“Hi”。

public async Task Confirmed(IDialogContext context, IAwaitable<bool> argument)
    {
        bool isCorrect = await argument;
        if (isCorrect)
        { }
        else
        { }
    }
