  t.Start();
  Console.WriteLine("main()");
  Console.ReadKey();
 }
 static void DownLoadFile_My( ){

  Thread.Sleep(2000);
  Console.WriteLine("下载完成！");
 }

 public static void Main(string[] args){
  TaskFactory tf=new TaskFactory();
  tf.StartNew(DownLoadFile_My);
  Console.WriteLine("main()");
  Console.ReadKey();
 }
 static void DownLoadFile_My( ){
  Console.WriteLine("开始下载...  线程ID："+Thread.CurrentThread.ManagedThreadId);
  Thread.Sleep(2000);
  Console.WriteLine("下载完成！");
 }
