C# constantly streaming serial data to arduino

Question

I am having trouble streaming comma delimited variables when a certain box is checked. I want the data stream to be constantly flowing to the arduino even if there is no change in the variables. The only time I have been able to get anything close I got stuck in an infinite loop. Here is the current code I have, any help would be appreciated.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Timers;

namespace feeder3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void streamBox_CheckedChanged(object sender, EventArgs e)
        {
            int a = 1;
            int b = 2;
            int c = 3;
                bool state = streamBox.Checked;
                while (state == true)
                {
                System.Console.WriteLine("{0},{1},{2}", a,b,c);

            }
        }

        private void stopStreamBtn_Click(object sender, EventArgs e)
        {
            streamBox.Checked = false;
        }
    }
}

I figured it out using the info barny gave me. I can now adjust the delay to match the baudrate.

  private async void streamBox_CheckedChanged(object sender, EventArgs e) { int a = 1; int b = 2; int c = 3; bool state = streamBox.Checked; while (state == true) { System.Console.WriteLine("{0},{1},{2}", a,b,c); await Task.Delay(10); } }
