c# - 结束对话 C# 机器人

Question

我正在用 C# 构建一个 ChatBot，我希望在收到一些消息后对话停止，但我不知道该怎么做。我已经设置了消息限制，我希望在达到此限制后不再发送消息。有我的代码:

private int NombreDeMessages;

protected override async Task MessageReceived(IDialogContext context, IAwaitable<IMessageActivity> item)
{
    var message = await item;
    NombreDeMessages += 1; 

    if (message.Text != null && NombreDeMessages < 3)
    {
         await base.MessageReceived(context, item);
    } 
    else
    { 
         var reply = context.MakeMessage();
         await context.PostAsync(reply);
         context.Wait(this.MessageReceived);
    }                
}

我删除了 HeroCard 部分，因为它在这里没用。

我想要的是在末尾的 context.Wait 之后，添加对话结束，这样用户就不能再与聊天机器人交谈了。

谢谢，解决了我的问题。如果它可以帮助某人，我会发布代码!

private int NombreDeMessages;
        protected override async Task MessageReceived(IDialogContext context, IAwaitable<IMessageActivity> item)
        {
            var message = await item;
            NombreDeMessages += 1;
            string code = EndOfConversationCodes.CompletedSuccessfully;
            CancellationToken cancellationToken = default(CancellationToken);


            if (message.Text != null && NombreDeMessages < 3)
            {
                await base.MessageReceived(context, item);

            }
            else if (message.Text != null && NombreDeMessages == 3)
            {
                AdaptiveCard card = new AdaptiveCard();
                card.Body.Add(new TextBlock()
                {
                    Text = "STOP FLOODING",
                    Weight = TextWeight.Bolder,
                    IsSubtle = true,
                    Wrap = true,
                    Size = TextSize.Large
                });

                card.Body.Add(new TextBlock()
                {
                    Text = "You have reach the limit of queries",
                    IsSubtle = false,
                    Wrap = true,
                    Size = TextSize.Normal
                });

                card.Body.Add(new Image()
                {
                    Url = "http://images.roadtrafficsigns.com/img/dp/lg/traffic-stop-sign.png",

                    HorizontalAlignment = HorizontalAlignment.Center,
                    Size = ImageSize.Stretch
                });

                Attachment attachment = new Attachment()
                {
                    ContentType = AdaptiveCard.ContentType,
                    Content = card
                };
                var flood = context.MakeMessage();
                flood.Attachments.Add(attachment);

                await context.PostAsync(flood);

            }
            else
            {

                var reply = context.MakeMessage();

                reply.Type = ActivityTypes.EndOfConversation;
                reply.AsEndOfConversationActivity().Code = code;

                await context.PostAsync(reply, cancellationToken);

            }

        }
