异步编程(三)

static void Main()
        {
            Console.WriteLine("Main Thread begin Thread ID:{0}",Thread.CurrentThread.ManagedThreadId);
            Program prgo = new Program();
            prgo.DoSomething(3);
            Console.WriteLine("Main Thread Lasting Thread ID:{0}", Thread.CurrentThread.ManagedThreadId);
            Console.Read();
        }

        public async void DoSomething(int id)//这里开启一个异步方法， Async 标志
        {
            await LoopingAjob(id);
           // await Task.Run(() => { Console.WriteLine("A task awit test {0}",id); });
        }
        public  Task LoopingAjob(int id)//这里是一个执行的任务
        {
            return Task.Run(()=> {
                Thread.Sleep(1000);
                Console.WriteLine("Task {0} run-> Thread ID:{1}",id,Thread.CurrentThread.ManagedThreadId);
            });   
        }
