在一些项目中，难免会有耗时的加载,如果加载时没有提示,给人一种假死的感觉，很不友好，那么现在福利来啦，WPF版的模态窗体，先上效果图
实际效果指针是转动的,话不多说，一大批干货来袭
XMAL的代码

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();
