How can we stop another thread based on a timer?

I was trying to use timer to stop another thread. But I didn't got a success. To better illustrate my point and for your easy to understand the key issue. I made the following sample example.

Your help is really appreciated

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;
using System.Timers;

namespace TestCodes
{


    public static class Program
    {
        private static Thread nT = new Thread(PrintABC);
        private static System.Timers.Timer aTimer;

        public static void Main()
        {



            aTimer = new System.Timers.Timer(1000);
            aTimer.Elapsed += TimerCallback;
            aTimer.Interval = 1000;
            aTimer.Enabled = true;
            nT.Start();
            Console.ReadLine();
        }

        private static void TimerCallback(Object o, ElapsedEventArgs e)
        {
            nT.Join();
            Console.WriteLine("Complete the PrintABC");
            GC.Collect();
        }

        private static void PrintABC()
        {
            for (int iter = 1; iter < 300; iter++)
            {
                Console.WriteLine(iter+"abc");
                Console.ReadKey();
                //Thread.Sleep(100);
            }
        }
    }
