l 多线程实现动画lambda
void mybtn_MouseLeave(objectsender,MouseEventArgs e)
{
//创建一个线程使用lambda表达式
Thread threa = newThread(() =>
{
//设定休息的时间
Thread.Sleep(1000);
mybtn.Dispatcher.Invoke(() =>
{
//用代码来触发点击事件
//RoutedEventArgs rea = new RoutedEventArgs();
//鼠标移入事件
MouseEventArgs mea= new MouseEventArgs(Mouse.PrimaryDevice, 0);
//指定触发事件的类型
mea.RoutedEvent= Button.MouseEnterEvent;
mybtn.RaiseEvent(mea);
});
});
threa.Start();
}
