1.先看效果

2.实现

1.主界面是MainWindow

上面就只摆放一个Button即可。在Button的点击事件中需要new一个弹出的NotificationWindow。代码如下：

 public static List<NotificationWindow> _dialogs = new List<NotificationWindow>();int i = 0;private void Button_Click(object sender, RoutedEventArgs e){i++;NotifyData data = new WpfApplication1.NotifyData();data.Title = "This is Title:"+i;data.Content = "content content content content content content content ";NotificationWindow dialog = new NotificationWindow();//new 一个通知dialog.Closed += Dialog_Closed;dialog.TopFrom = GetTopFrom();_dialogs.Add(dialog);dialog.DataContext = data;//设置通知里要显示的数据dialog.Show();}private void Dialog_Closed(object sender, EventArgs e){var closedDialog = sender as NotificationWindow;_dialogs.Remove(closedDialog);}

其中NotifyData类只有两个属性分别是Title和Content，给NotificationWindow提供所要展示的消息数据。

GetTopFrom方法用来获取弹出通知框的底部应该在WorkArea（工作区）的哪个位置:

 double GetTopFrom(){//屏幕的高度-底部TaskBar的高度。double topFrom = System.Windows.SystemParameters.WorkArea.Bottom - 10;bool isContinueFind = _dialogs.Any(o => o.TopFrom == topFrom);while (isContinueFind){topFrom = topFrom - 100;//此处100是NotifyWindow的高isContinueFind = _dialogs.Any(o => o.TopFrom == topFrom);}if (topFrom <= 0)topFrom = System.Windows.SystemParameters.WorkArea.Bottom - 10;return topFrom;}

2.弹出的通知是一个NotificationWindow

这个Window就一个Image,一个Button，两个TextBlock。
就长这个样子：

• Image用来显示通知的图标，Button用来关闭当前window，两个TextBlock的Text属性分别banding到NotifyData类的Title和Content属性上，用来显示消息的标题和正文。

• 在NotificationWindow中添加如下代码：

public double TopFrom{get; set;}
private void NotificationWindow_Loaded(object sender, RoutedEventArgs e)
{NotificationWindow self = sender as NotificationWindow;if (self != null){self.UpdateLayout();SystemSounds.Asterisk.Play();//播放提示声double right = System.Windows.SystemParameters.WorkArea.Right;//工作区最右边的值self.Top = self.TopFrom - self.ActualHeight;DoubleAnimation animation = new DoubleAnimation();animation.Duration = new Duration(TimeSpan.FromMilliseconds(NotifyTimeSpan));//NotifyTimeSpan是自己定义的一个int型变量，用来设置动画的持续时间animation.From = right;animation.To = right - self.ActualWidth;//设定通知从右往左弹出self.BeginAnimation(Window.LeftProperty, animation);//设定动画应用于窗体的Left属性Task.Factory.StartNew(delegate{int seconds = 5;//通知持续5s后消失System.Threading.Thread.Sleep(TimeSpan.FromSeconds(seconds));//Invoke到主进程中去执行Invoke(self, delegate{animation = new DoubleAnimation();animation.Duration = new Duration(TimeSpan.FromMilliseconds(NotifyTimeSpan));animation.Completed += (s, a) => { self.Close(); };//动画执行完毕，关闭当前窗体animation.From = right - self.ActualWidth;animation.To = right;//通知从左往右收回self.BeginAnimation(Window.LeftProperty, animation);});});}
}
static void Invoke(Window win, Action a)
{win.Dispatcher.Invoke(a);
}

上面这段代码注释已经很明白了，没什么好讲的。

• 当Button按钮点击后执行关闭窗体操作,这段代码其实跟上面的类似：

private void ButtonClose_Click(object sender, RoutedEventArgs e)
{double right = System.Windows.SystemParameters.WorkArea.Right;DoubleAnimation animation = new DoubleAnimation();animation.Duration = new Duration(TimeSpan.FromMilliseconds(NotifyTimeSpan));animation.Completed += (s, a) => { this.Close(); };animation.From = right - this.ActualWidth;animation.To = right;this.BeginAnimation(Window.LeftProperty, animation);
}

3.结束了，就这么简单
