How to pass user text directly to LUIS at Prompt choice for which the is option does not exist

Question

I have been working on the Bot Framework, in that i have created the Prompt choice as Yes, No, I'm independent type of question. But if i enter the any text which was not present the option List then i should pass the user text to LUIS for hitting the corresponding Intent. I have tried that by getting the user text in Catch block but (await result) not getting the user text.enter image description here

Consider the following prompt:

PromptDialog.Choice(context, this.ChoiceReceivedAsync, new List<string>() { "Choice 1", "Choice 2" }, "stuff and things");

in the resume after method, you can apply logic on the users choice like:

    private Task ChoiceReceivedAsync(IDialogContext context, IAwaitable<string> result)
    {
       Activity a = context.Activity as Activity;
        switch (a.Text)
        {
            case "Choice 1":
                //do stuff
                break;
            case "Choice 2":
                //do stuff
                break;
            default:
                context.Forward(new Luis(), afterLuis, context.Activity, CancellationToken.None);
                break;
        }

        a = a.CreateReply("things");
        context.PostAsync(a);
        return Task.CompletedTask;
    }

That way if the user enters anything other than a choice it will be sent to Luis() which in my case is a public class Luis : LuisDialog<object> or a Luis dialog to handle Luis calls.

You could also have done it like this calling the LUIS API rather than using a LUIS dialog.

    private async Task ChoiceReceivedAsync(IDialogContext context, IAwaitable<string> result)
    {
       Activity a = context.Activity as Activity;
        switch (a.Text)
        {
            case "Choice 1":
                //do stuff
                break;
            case "Choice 2":
                //do stuff
                break;
            default:
                using (HttpClient client = new HttpClient())
                {
                    string RequestURI = "https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/YOUR_MODEL_ID?" +
                                        "subscription-key=YOUR_SUBSCRIPTION_KEY&amp;verbose=true&amp;timezoneOffset=0&amp;q=" +
                                        a.Text;

                    HttpResponseMessage msg = await client.GetAsync(RequestURI);
                    if (msg.IsSuccessStatusCode)
                    {
                        var JsonDataResponse = await msg.Content.ReadAsStringAsync();
                        LUISData luisData = JsonConvert.DeserializeObject<LUISData>(JsonDataResponse);
                    }
                }
                break;
        }
        a = a.CreateReply("things");
        await context.PostAsync(a);
    }

in order to do it this way you would have to add classes like this to support the deserialization.

    public class LUISData
    {
        public string query { get; set; }
        public LUISIntent[] intents { get; set; }
        public LUISEntity[] entities { get; set; }
    }
    public class LUISEntity
    {
        public string Entity { get; set; }
        public string Type { get; set; }
        public string StartIndex { get; set; }
        public string EndIndex { get; set; }
        public float Score { get; set; }
    }
    public class LUISIntent
    {
        public string Intent { get; set; }
        public float Score { get; set; }
    }
