Task的使用

在.net4.0的时候推出的Task

using System;

using System.Threading;

using System.Threading.Tasks;



namespace TaskDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine("Main Thread = {0}", Thread.CurrentThread.ManagedThreadId);

            Console.WriteLine();



            Action<object> action = (object obj) =>

            {

                Console.WriteLine("obj = {0}{3}Task = {1}{3}Thread = {2}{3}", obj.ToString(), Task.CurrentId, Thread.CurrentThread.ManagedThreadId, Environment.NewLine);

            };



            Task t1 = new Task(action, "t1 = new Task(Action<Object>, Object).Start()");



            Task t2 = Task.Factory.StartNew(action, "t2 = Task.Factory.StartNew(Action<Object>, Object)");

            t2.Wait();



            t1.Start();



            Console.WriteLine("t1 has been launched.");

            Console.WriteLine();



            t1.Wait();



            Task t3 = new Task(action, "t3 = new Task(Action<Object>, Object).RunSynchronously()");

            t3.RunSynchronously();



            t3.Wait();

            Console.ReadKey();

        }

    }

}

执行结果
