C#异步编程のParallel（并行）

Parallel是循环中开启多线程

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

Stopwatch watch1 = new Stopwatch(); watch1.Start(); for (int i = 1; i <= 10; i++) {     Console.Write(i + ",");     Thread.Sleep(1000); } watch1.Stop(); Console.WriteLine(watch1.Elapsed);   Stopwatch watch2 = new Stopwatch(); watch2.Start();   //会调用线程池中的线程 Parallel.For(1, 11, i => {     Console.WriteLine(i + ",线程ID:" + Thread.CurrentThread.ManagedThreadId);     Thread.Sleep(1000); }); watch2.Stop(); Console.WriteLine(watch2.Elapsed);

　　循环List<T>
