线程和CPU使用率100

问题描述

如何使用线程使用无限循环....

当我执行以下代码时...占用100％的CPU使用率...

我如何将CPU使用率至少降低50％

hi ,

how to use the infinite loop using threading....

while i am executing below code... it''s taking 100 % usage of the CPU...

How i can reduce the CPU usage at-least 50 %

namespace ThreadingIssue
{
    class Program
    {
        static void Main(string[] args)
        {
            ThreadStart ts = new ThreadStart(Test);
            Thread th = new Thread(ts);
            th.IsBackground = true;
            th.Priority = ThreadPriority.Lowest;
            th.Start();

            ts = new ThreadStart(Test1);
            th = new Thread(ts);
            th.IsBackground = true;
            th.Priority = ThreadPriority.Lowest;
            th.Start();

            Console.ReadKey();
        }

        static void Test()
        {
            while (true)
            {

            }
        }

        static void Test1()
        {
            while (true)
            {

            }
        }
    }
}

推荐答案

MyEventWaitHandle.WaitOne();

或者，您可以将WaitOne与参数一起使用，这是超时.

在此调用中，操作系统关闭线程，并且从不将其调度回执行，直到将其唤醒.该线程将完全花费零CPU时间.只能从另一个线程调用MyEventWaitHandle.Set或Thread.Abort来唤醒该线程.就这样.

Alternatively, you can use WaitOne with a parameter, which is a timeout.

On this call OS switches the thread off and never schedules it back to execution until it is waken up. The thread will spend exactly zero CPU time. The thread can be waken up only be MyEventWaitHandle.Set or Thread.Abort called from the other thread. That''s it.

            _AREvt = new AutoResetEvent(false);

            ThreadStart ts = new ThreadStart(Test);
            Thread th = new Thread(ts);
            th.IsBackground = true;
            th.Priority = ThreadPriority.Lowest;
            th.Start();

            ts = new ThreadStart(Test1);
            th = new Thread(ts);
            th.IsBackground = true;
            th.Priority = ThreadPriority.Lowest;
            th.Start();

            Console.ReadKey();

        static void Test()

            while (true)
            {

                //do what you need todo
                _AREvt.WaitOne(10, true);

            }
        }
