Question

使用僵尸模拟器：

在MessagesController中使用此代码：

 await Conversation.SendAsync(activity, () => new RootLuisDialog());

在RootLuisDialog中：

        [LuisIntent("")]
        [LuisIntent("None")]
        public async Task None(IDialogContext context, LuisResult result)
        {
            string message = $"Sorry, I did not understand '{result.Query}'. Type 'help' if you need assistance.";

            await context.PostAsync(message);

            context.Wait(this.MessageReceived);
        }

这是一个例外：

我不太确定我明白这是什么例外...... 一些帮助？

编辑：我使用参数 - activity的rootluisdialog的新构造函数解决了这个问题。

await Conversation.SendAsync（activity，（）=＆gt; new RootLuisDialog（activity））; 然后在RootLuisDialog中我有这个：

 Activity activity;
public RootLuisDialog(Activity activity)
        {
            this.activity = activity;

        }

Answer 1

Activity课程不可串行化，这是您所看到的错误。 LuisDialog中的所有公共或受保护属性都需要是可序列化的，以便它们可以存储为响应之间的上下文。

假设您的Dialog类继承自LuisDialog，那么这应该已经在处理从意图中获取活动 - 通常您将使用来自LUIS的上下文和结果而不是直接活动（就像你创建一个直接IDialog实现一样）。

从控制器传递它也不会做你期望的事情，因为它不会被包含在对话的后续呼叫中。
