当线程多的时候就会造成CPU内存占用率过高

 private void button1_Click(object sender, EventArgs e){Thread TH1, TH2, TH3, TH4, TH5;TH1 = new Thread(Thread1){IsBackground = true};TH2 = new Thread(Thread2){IsBackground = true};TH3 = new Thread(Thread3){IsBackground = true};TH4 = new Thread(Thread4){IsBackground = true};TH5 = new Thread(Thread5){IsBackground = true};TH1.Start();TH2.Start();TH3.Start();TH4.Start();TH5.Start();}public void Thread1(){while (true) ;}public void Thread2(){while (true) ;}public void Thread3(){while (true) ;}public void Thread4(){while (true) ;}public void Thread5(){while (true) ;}

上面这段代码，CPU的占用率高

解决方法：

只要我们上每个线程岔开时间执行即可，我们在每一段循环中增加thread.sleep(1)，让线程休眠等待。

        public void Thread1(){while (true)Thread.Sleep(1);}public void Thread2(){while (true)Thread.Sleep(1);}public void Thread3(){while (true)Thread.Sleep(1);}public void Thread4(){while (true)Thread.Sleep(1);}public void Thread5(){while (true)Thread.Sleep(1);}
