ใช้ Threading กับ Class อันนี้ก็น่าสนนะผมว่า หุหุ

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

namespace Threading
{
    class MyThread
    {
        String myName;
        public MyThread(String name)
        {
            myName = name;
        }
        public void Runt()
        {
            for (int i = 0; i <= 100; i++)
            {
                Random RandomClass = new Random();
                int RandomNumber = RandomClass.Next(50, 100);
                System.Threading.Thread.Sleep(RandomNumber);
                Console.WriteLine(myName+" => "+RandomNumber);
            }
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            MyThread mm = new MyThread("Chiwa");
            Thread t = new Thread(mm.Runt);
            t.Start();
             mm = new MyThread("Pee");
            t = new Thread(mm.Runt);
            t.Start();
            Console.Read();
        }
    }
}
