C# 如何在由Microsoft bot frame work开发的聊天机器人中获得直接响应初始对话框

我现在正在开发聊天机器人，可以回答客户提出的问题。我想删除第一条通讯线路“键入一些单词以回答问题”。然而，我找不到路

初始化通信

if (member.Id != turnContext.Activity.Recipient.Id)
{
    var reply = MessageFactory.Text("質問を続けるには何か入力してください。");
    await turnContext.SendActivityAsync(reply, cancellationToken);
}

向客户提问

private async Task<DialogTurnResult> InputQuestionAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        _logger.LogInformation("MainDialog.InputQuestionAsync");
        var promptOptions = new PromptOptions { Prompt = MessageFactory.Text("ご質問を話し言葉で入力して下さい。") };
        return await stepContext.PromptAsync(nameof(TextPrompt), promptOptions, cancellationToken);
    }

private async Task<DialogTurnResult> ShowCardStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        _logger.LogInformation("MainDialog.ShowCardStepAsync");
        var receivedMessage = (string)stepContext.Result;
        var userProfile = await _userProfileAccessor.GetAsync(stepContext.Context, () => new UserProfile(), cancellationToken);
        userProfile.Question = receivedMessage;
        *
        *
        *
        *
        msg = msg + sec.ToString() + ".知りたい質問がありません\n\n" + third.ToString() + ".質問を変える\n\n";
        var reply = MessageFactory.Text(msg);
        list1.Add(sec.ToString());
        list1.Add(third.ToString());
        reply.Attachments.Add(Cards.GetHeroCard(list1).ToAttachment());
        await stepContext.Context.SendActivityAsync(reply, cancellationToken);

        var promptOptions = new PromptOptions { Prompt = MessageFactory.Text("番号を押してください") };
        return await stepContext.PromptAsync(nameof(TextPrompt), promptOptions, cancellationToken);
        }
    }

private async Task InputQuestionAsync（WaterCallStepContext stepContext，CancellationToken CancellationToken）
{
_logger.LogInformation（“MainDialog.InputQuestionAsync”）；
var promptOptions=newpromptoptions{Prompt=MessageFactory.Text（“ご質問を話し言葉で入力して下さい。") };
返回wait wait stepContext.PromptAsync（名称（TextPrompt）、提示、取消令牌）；
}

回答问题

    {
        _logger.LogInformation("MainDialog.InputQuestionAsync");
        var promptOptions = new PromptOptions { Prompt = MessageFactory.Text("ご質問を話し言葉で入力して下さい。") };
        return await stepContext.PromptAsync(nameof(TextPrompt), promptOptions, cancellationToken);
    }

private async Task<DialogTurnResult> ShowCardStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {

        var receivedMessage = (string)stepContext.Result;
        var userProfile = await _userProfileAccessor.GetAsync(stepContext.Context, () => new UserProfile(), cancellationToken);

        var reply = MessageFactory.Text(msg);

        var promptOptions = new PromptOptions { Prompt = MessageFactory.Text("番号を押してください") };
        return await stepContext.PromptAsync(nameof(TextPrompt), promptOptions, cancellationToken);
        }
    }

private async Task showcardstepsync（waterwallstepcontext stepContext，CancellationToken CancellationToken）
{
_logger.LogInformation（“MainDialog.ShowCardStepAsync”）；
var receivedMessage=（字符串）stepContext.Result；
var userProfile=await _userProfileAccessor.GetAsync（stepContext.Context，（）=>newuserprofile（），cancellationToken）；
userProfile.Question=receivedMessage；
*
*
*
*
msg=msg+sec.ToString（）+”。知りたい質問がありません\n\n“+third.ToString（）+”。質問を変える\n\n“；
var reply=MessageFactory.Text（msg）；
列表1.Add（sec.ToString（））；
list1.Add（third.ToString（））；
reply.Attachments.Add（Cards.GetHeroCard（list1.ToAttachment（））；
Wait stepContext.Context.SendActivityAsync（回复、取消令牌）；
var promptOptions=newpromptoptions{Prompt=MessageFactory.Text（“番号を押してください") };
返回wait wait stepContext.PromptAsync（名称（TextPrompt）、提示、取消令牌）；
}
}

添加

var accessor = ConversationState.CreateProperty<DialogState>(nameof(DialogState));
await Dialog.RunAsync(turnContext, accessor, cancellationToken);

var accessor=ConversationState.CreateProperty（nameof（DialogState））；
wait Dialog.RunAsync（turnContext、访问器、cancellationToken）；

在 OnMembersAddedAsync和OnMessageActivityAsync解决了此问题
