(Task)任务异步(TAP)的使用

任务有返回值例子：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;

 namespace Demo
 {
     class Program
     {

         static void Main(string[] args)
         {

             System.Threading.Tasks.Task<string> task = Task.Factory.StartNew<string>(Test);

             Console.WriteLine("Result:" + task.Result);
             Console.WriteLine("Status:" + task.Status);
             Console.WriteLine("IsFaulted:" + task.IsFaulted);
             Console.WriteLine("IsCompleted:" + task.IsCompleted);
             Console.WriteLine("IsCanceled:" + task.IsCanceled);
             Console.ReadKey();
         }

         public static string Test()
         {
             Console.WriteLine("调用test方法："+"ddddfdfd");
             return "调用异步方法返回的结果";
         }

     }
 }

下图是上面的代码的运行结果：

没有返回值的任务：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;

 namespace Demo
 {
     class Program
     {

         static void Main(string[] args)
         {

             System.Threading.Tasks.Task task = Task.Factory.StartNew(Test);

             Console.WriteLine("Status:" + task.Status);
             Console.WriteLine("IsFaulted:" + task.IsFaulted);
             Console.WriteLine("IsCompleted:" + task.IsCompleted);
             Console.WriteLine("IsCanceled:" + task.IsCanceled);
             Console.ReadKey();
         }

         public static void Test()
         {
             Console.WriteLine("调用test方法："+"ddddfdfd");
         }

     }
 }

下面是上述代码运行的结果：
