cpu使用率太高

Question

编写程序如下：
class Program
    {
        static void Main(string[] args)
        {
            Thread thread1 = new Thread(new ThreadStart(Fun1));
            Thread thread2 = new Thread(new ThreadStart(Fun2));
            thread1.Start();
            Thread.Sleep(1000);
            thread2.Start();
        }        static void Fun1()
        {
            int j = 0;
            while (true)
            {                for (int i = 0; i < 10000; i++)
                {
                    j = j + i;
                }
            }
        }        static void Fun2()
        {
            int j = 0;
            while (true)
            {                for (int i = 0; i < 10000; i++)
                {
                    j = j + i;
                }
            }
        }
    }
每次运行cpu使用率都是100%，怎么样能是cpu的使用率降下来呢？

Answer 1

你这个当然会100%的，在while(true)里加个Thread.Sleep(100);比如：
            while (true)
            {                for (int i = 0; i < 10000; i++)
                {
                    j = j + i;
                }
                Thread.Sleep(100);
            } 

Answer 2

  for (int i = 0; i < 10000; i++) 
                { 
                    j = j + i; 
                  加 Thread.Sleep(100);                }
