我想调用一个对话框类（我添加了旋转木马）。
这是我的代码
[LuisIntent("Greeting")]
public async Task Greeting(IDialogContext context, LuisResult result)
{
context.Call(new GuesserBot, this.ResumeAfterOptionDialog);
}

我收到了这个错误：
错误CS0411：方法的类型参数＆＃39; IDialogStack.Call（IDialog，ResumeAfter）＆＃39;无法从使用中推断出来。尝试明确指定类型参数。
ResumeAfterOption：
private async Task ResumeAfterOptionDialog(IDialogContext context, IAwaitable<object> result)
{
await context.PostAsync("Do you want something else!");
}
你可以帮助我在调用一个意图时如何显示旋转木马吗？
我可以在我拥有luis对话意图的同一个类中添加轮播代码吗？
答案 0 :(得分：2)
问题是您正在尝试调用非对话框的内容，因此编译器无法推断出类型。通过查看您的代码，您似乎正在尝试调用GuesserBot（这不是对话框），但是您应该调用GuesserDialog。
[LuisIntent("Greeting")]
public async Task Greeting(IDialogContext context, LuisResult result)
{
context.Call(new GuesserDialog(), this.ResumeAfterOptionDialog);
}
顺便说一句，我注意到您的GuesserDialog不可序列化，因此请务必为其添加[Serializable]属性;否则以后就会失败。
关于你的第二个问题，是的，你可以在基于LuisDialog的课程中添加轮播代码。
