HorizontalAlignment="Left" Margin="396,668,0,0" VerticalAlignment="Top" RenderTransformOrigin="0.274,0.462"/> 368 </Grid> 369 </Window>
后台C#代码
1 public partial class CoverForm : Window 2 { 3 public CoverForm(Action workAction) 4 { 5 InitializeComponent(); 6 this.workAction = workAction; 7 System.Threading.Thread t = new System.Threading.Thread(ExecWorkAction); 8 t.IsBackground = true; 9 t.Start(); 10 } 11 private Action workAction = null; 12 private void ExecWorkAction() 13 { 14 try 15 { 16 var workTask = new Task(workAction); 17 workTask.Start(); 18 Task.WaitAll(workTask); 19 } 20 finally 21 { 22 this.Dispatcher.Invoke(new Action(() => { this.Close(); })); 23 } 24 } 25 }
调用的代码
1 new CoverForm(() => {耗时的代码 }); }).Show();
有需要的尽管拿去吧，要问我是谁，请叫我是雷锋。
