C# /ASP.NET code behind showing how to process and use Tropo Result object.

Ask.cs

using System;
using TropoCSharp.Tropo;

namespace TropoDemo
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            // Create a new instance of the Tropo object.
            Tropo tropo = new Tropo();

            // A prompt to use with the Ask.
            Say say = new Say("This is a Tropo test application. Please enter a number 0 through 9.");

            // Choices for the Ask.
            Choices choices = new Choices("[1 DIGIT]");

            // Build the Ask object.
            tropo.Ask(3, false, choices, null, "test", true, say, 30);
            
            // Set the handler for the continue event, fired when the caller enters input.
            tropo.On("continue", "Result.aspx", null);

            // Render the dialog JSON for Tropo to consume.
            Response.Write(tropo.RenderJSON());

        }
