在 QnA Maker API 中，当没有找到结果时，它会返回一些默认消息，或者我们可以更改该消息，但是我想在没有结果时运行一个函数/方法。下面是代码。

public QnaDialog(): base(
        new QnAMakerService(new QnAMakerAttribute(ConfigurationManager.AppSettings["QnaSubscriptionKey"], 
        ConfigurationManager.AppSettings["QnaKnowledgebaseId"], "Hmm, I wasn't able to find any relevant content. Can you try asking in a different way? or try with typing help.", 0.5)))
    {
        //this is what i want to call, this is working but **i am not able to get query text here**
        SendEmail email = new SendEmail();
        email.SendEmailtoAdmin("Query_Text", "Email ID");
    }
