.net Parallel 介绍

可以并行执行，代码如下：

    public static void ParallelInvoke()
        {
            Stopwatch sp = new Stopwatch();
            sp.Start();
            Run1();
            Run2();
            sp.Stop();
            Console.WriteLine("Normal run " + sp.ElapsedMilliseconds + " ms.");
            sp.Restart();
            Parallel.Invoke(Run1, Run2);
            sp.Stop();
            Console.WriteLine("Parallel run " + sp.ElapsedMilliseconds + " ms.");
        }
        public static void Run1()
        {
            Thread.Sleep(2000);
            Console.WriteLine("I am Run1");
        }
        public static void Run2()
        {
            Thread.Sleep(3000);
            Console.WriteLine("I am Run2");
        }
