Parallel与PLINQ简单示例

            int[] nums = new[] { 1, 2, 3, 4 };
            Parallel.For(0, nums.Length, i =>
            {
                Console.WriteLine("下标：{0}，值：{1}", i, nums[i]);
            });

            var ltModel = new List<UserInfo>();
            for (int i = 1; i <= 5; i++)
            {
                var item = new UserInfo { No = i, Name = "名字" + i };
                ltModel.Add(item);
            }
            Parallel.ForEach(ltModel, item =>
            {
                Console.WriteLine("No:{0}, Name:{1}", item.No, item.Name);
            });

            var ltTask = new List<Action>();
            for (int i = 1; i <= 5; i++)
            {
                int j = i;
                ltTask.Add(() =>
                {
                    Console.WriteLine("启动任务" + j);
                });
            }
            Parallel.Invoke(ltTask.ToArray());

            var ltNum = new List<int>() {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
            var resultNum = (from n in ltNum.AsParallel() where n>=3 orderby n descending select n).ToArray();
            foreach (var item in resultNum)
            {
                Console.WriteLine("Num: {0}", item);   
            }
