Parallel类

1，用Parallel.For()方法循环

    class Program
    {
        static void Main(string[] args)
        {
            //=============================第一种
            Parallel.For(0,//第一个参数：开始索引
                10,//第二个参数：最大索引
                (i, parallelLoopState) =>//第三个参数：循环委托方法
                {
                    Console.WriteLine("索引：{0},任务id：{1},线程id：{2}", i, Task.CurrentId, Thread.CurrentThread.ManagedThreadId);
                });

            //=============================第二种
            Parallel.For<string>(0,//第一个参数：开始索引
                10,//第二个参数：最大索引
                //第三个参数：线程开始的方法
                () => { Console.WriteLine("线程开启:{0}", Thread.CurrentThread.ManagedThreadId); return "aa"; },
                //第四个参数：循环委托方法
                (i, pls, str1) => { Console.WriteLine("索引：{0},线程id:{1},任务id:{2}", i, Thread.CurrentThread.ManagedThreadId,Task.CurrentId); return "bb"; },
                //第五个参数：线程结束的方法
                str => Console.WriteLine("线程结束:{0}", Thread.CurrentThread.ManagedThreadId));
            Console.ReadLine();
        }
    }

2，用Parallel.ForEach()方法循环

    class Program
    {
        static void Main(string[] args)
        {
            string[] data = new string[] { "1", "2", "3", "4" };
            Parallel.ForEach(data, r => {
                Console.WriteLine(r);
            });

            Parallel.ForEach<string>(data, (r, p, l) =>
            {
                //r：遍历数组的值
                //l：数组的索引
                Console.WriteLine(r + "," + l);
            });
 
            Console.ReadKey();
        }
    }

3，用Parallel.ForEach()方法并行调用多个方法

    class Program
    {
        static void Main(string[] args)
        {
            Parallel.Invoke(Foo, Bar);
            Console.ReadLine();
        }
        private static void Foo()
        {
            Console.WriteLine("Foo; task:{0};threadis:{1}", Task.CurrentId, Thread.CurrentThread.ManagedThreadId);
        }
        private static void Bar()
        {
            Console.WriteLine("Bar; task:{0};threadis:{1}", Task.CurrentId, Thread.CurrentThread.ManagedThreadId);
        }
    }
