WPF遮蔽层的实现
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

后台C#代码
public partial class CoverForm : Window
{
public CoverForm(Action workAction)
{
InitializeComponent();
this.workAction = workAction;
System.Threading.Thread t = new System.Threading.Thread(ExecWorkAction);
t.IsBackground = true;
t.Start();
}
private Action workAction = null;
private void ExecWorkAction()
{
try
{
var workTask = new Task(workAction);
workTask.Start();
Task.WaitAll(workTask);
}
finally
{
this.Dispatcher.Invoke(new Action(() => { this.Close(); }));
}
}
}
调用的代码
new CoverForm(() => {耗时的代码 }); }).Show();
