如何在 Bot Framework 中将 activity 传递给 formbuilder class

Question

我有下面的 LUIS 对话框 class，我从中将它重定向到 formbuilder class，我想将一个 context.Activity 传递给我的 formbuilder 方法，它驻留在另一个 class 是在 code.How 之后给出的吗？

public class LUISManager : LuisDialog<object>
{
    [LuisIntent("BookFlight")]
    public async Task BookFlight(IDialogContext context, LuisResult result)
    {    
        //context.Activity       
        FlightBooking cb = new FlightBooking();
        BuildFormDelegate<FlightBooking> MakeFlightBookingForm = FlightBooking.BuildForm;
        var flightBooking = new FormDialog<FlightBooking>(cb, MakeFlightBookingForm, FormOptions.PromptInStart, null);
        context.Call<FlightBooking>(flightBooking, FlightBookingComplete);
    }
}

[Serializable]
public class FlightBooking
{
public static IForm<FlightBooking> BuildForm()
{
    return new FormBuilder<FlightBooking>().Message("Tell me meeting details!")
    .Field(nameof(title))
    .Field(nameof(StartDate))//, validate: ValidateStartDate
    .Field(nameof(EntryTime), validate:ValidateCallTime)
    .Build();
}
},

我知道我们可以在 BuildForm 方法中传递 "IDialogContext context" 参数，但如何从 BuildFormDelegate

传递它

Answer 1

将构造函数更改为：

public static IForm<FlightBooking> BuildForm(IDialogContext context)
{}

然后你可以使用lambda表达式：

BuildFormDelegate<FlightBooking> MakeFlightBookingForm = ()=>FlightBooking.BuildForm(context);
