使用自旋算法实现“两个线程轮流打印0到100奇偶数？”

volatile static int i = 0;
public static void Main(String[] args)
        {
            Thread thread1 = new Thread(() =>
            {
                while (i <= 100)
                {
                    if (i % 2 == 0)
                    {
                        Console.WriteLine(i + "== 偶数");
                        i++;
                    }
                }
            });
            Thread thread2 = new Thread(() =>
            {
                while (i <= 100)
                {
                    if (i % 2 ==1  )
                    {
                        Console.WriteLine(i + "== 奇数");
                        i++;
                    }
                }
            });
            thread1.Start();
            thread2.Start();
            Console.ReadKey();
        }
