How to forward from RootDialog to LuisDialog in Bot Framework

Question

I\'m creating a bot for FAQ . When bot start conversations send a PromptDialog with 2 options: english, french.

I want to forward the dialog to EnglishLuis when user

Answer 1

First, doing

context.Wait(this.MessageReceived);
context.Done(true);

it's wrong. You need to choose: or you wait for a new message in the EnglishDialog or you end the EnglishDialog (with Done)

Then, you are trying to send a string in the context.Forward and you need to forward an IMessageActivity. And I suspect you want to send the original message, so you will need to save that in global variable before continuing with the prompt. Try with:

var newMessage = context.MakeMessage();
newMessage.Text = this.originalMessageText //the variable that contains the text of the original message that you will have to save at MessageReceiveAsync
await context.Forward(new EnglishLuis(), ResumeAfterDialog, newMessage, CancellationToken.None);


MessageReceivedAsync in RootDialog should looks like:

 private async Task MessageReceiveAsync(IDialogContext context, IAwaitable result)
    {
        var reply = await result;
        if (reply.Text.ToLower().Contains("help"))
        {
            await context.PostAsync("You can implement help menu here");
        }
        else
        {
            this.originalMessage = reply.Text;
            await ShowMainmenu(context);
        }
    }
