我 写着 优先级怎么没有用

  class Program
    {
        public static int count = 100;
        public static object objent1 = new object();
        static void Main(string[] args)
        {
            //Worker work = new Worker("aaa");
            //Worker work1 = new Worker("bbb");
            //work.thread.Priority = ThreadPriority.Highest;
            //work1.thread.Priority = ThreadPriority.Lowest;
            //work.thread.Start();
            //work1.thread.Start();
            
            Thread thread1 = new Thread(new ThreadStart(aaa));
            thread1.Start();
            Thread thread2 = new Thread(new ThreadStart(bbb));
            thread2.Start();
            thread1.Priority = ThreadPriority.Highest;
            System.Console.ReadLine();
        }
        static void aaa()
        {
            for (int i = 0; i < 50; i++)
            {
                jian1();
                System.Console.WriteLine(count.ToString()+"aaa");
            }
        }
        static int jian1()
        {
            //lock (Program.objent1)
            //{
                if (count > 0)
                {
                    count = count - 1;
                }
                else
                {
                    return 0;
                }
                return count;
            //}
        }
        static void bbb()
        {
            for (int i = 0; i < 50; i++)
            {
                jian1();
                System.Console.WriteLine(count.ToString()+"bbb");
            }

        }
        }
