C#多线程、异步

1.如果数据仅用于展示，或者对数据的获取没有先后要求，可以使用如下线程

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

private void AutoUpdate_Loaded(object sender, RoutedEventArgs e) {Thread ThreadUpdate = new Thread(Update);}   private void Update() { try { Thread.Sleep(2000);   //执行更新 ExcuteUpdate();   Dispatcher.BeginInvoke(new Action(delegate { this.Close(); //执行界面层：关闭窗体 }));   } catch (Exception ex) { 　　MessageBox.Show(ex.Message); } }

2.异步
