class Program
{
static void Main(string[] args)
{

         Thread thread1 = new Thread(new ThreadStart(fun_thread1));            
         Thread thread2 = new Thread(new ThreadStart(fun_thread2));
         thread1.Start();
         thread2.Start();
     }
    static void fun_thread1()
     {
         for (int i = 1; i < 60;i++ )
         {
            Console.WriteLine( "  1");
            Thread.Sleep(30);
         }
     }
    static void fun_thread2()
     {
         for (int i = 1; i < 60;i++ )
         {
            Console.WriteLine( "  2");
            Thread.Sleep(30);
         }
     }

}
为什么运行出来的结果是1、2交替的啊？？不应该是无序的吗？？？不知道是不是sleep和时间片的原因，把sleep去掉就是无序了，但是我需要让这两个进程隔一段时间执行一次而且要无序~~~

新人求助啊！！！
