C#~异步编程再续~大叔所理解的并行编程(Task&Parallel)

返回目录

并行这个概念出自.net4.5，它被封装在System.Threading.Tasks命名空间里，主要提供一些线程，异步的方法，或者说它是对之前Thread进行的二次封装，为的是让开发人员更方便的调用它，对于异步与多线程我们在之前的几讲里已经介绍过了，今天主要说说并行，并行也可以叫并行计算，即对于一个大任务，使用多个线程去计算它，这可以充分发挥多核ＣＰＵ的优势，可以说是大事所趋！

对于两个任务，任务１执行需要１秒，任务２执行需要３秒，那么，如果顺序执行，它需要的时间为4秒（1+3），而如果是并行编程，那就运行时间为３秒，即（１和３一起运行，取最长的时间），这就是并行计算的魅力！

下面看两种并行的实现方式

一 Task实现的并行

      #region 并行Task

            Console.WriteLine(DateTime.Now);

            var task = Task.WhenAll(Task.Run(() => { Thread.Sleep(); }), Task.Run(() => { Thread.Sleep(); }));//多个task并行执行，不阻塞

            task.ContinueWith((ctw) =>//当task完成后，执行这个回调

            {

                Console.WriteLine("并行完成" + DateTime.Now);

            });

            Console.WriteLine(DateTime.Now);

       #endregion

二 Parallel实现的并行

　　　　　#region 并行Parallel

            Console.WriteLine(DateTime.Now);

            Parallel.Invoke(() =>

            {

                Console.WriteLine(Thread.CurrentThread.ManagedThreadId);

                Thread.Sleep();

            }, () =>

            {

                Console.WriteLine(Thread.CurrentThread.ManagedThreadId);

                Thread.Sleep();

            });

            Console.WriteLine(DateTime.Now);

            Console.ReadKey();

          #endregion

通过上面的图我们可以看到，在进行并行测试时，运行时间为两秒！
