WPF制作窗口的启动和关闭动画
但我们今天的主题是窗口启动时和关闭时都展示动画，如何进行动画处理，我以前写过一些WPF相关的文章。
要将窗口进行自定义，首先我们要去掉默认窗口的边框、背景色和标题栏。
这个不难，在WPF中，要把窗体彻底透明，只要做三件事即可：
（1）设置WindowStyle属性为None。
（2）AllowsTransparency属性设置为true。
（3）Background属性为Transparent。
为了使窗体易于控件，可以考虑设置ResizeMode="NoResize"。
窗口变成了透明，这使得窗口的整个区域就需要我们自己来设计了。
为了使自定义的窗口也有边框，在最外层，我们应该考虑使用Border，然后里面放一个Grid，这个Grid划分为两行，第一行作为标题栏，第二行作为窗口的客户区域。

<Border x:Name="wb" CornerRadius="5" BorderThickness="3" BorderBrush="#FF1A55AA">
<Border.Background>
<LinearGradientBrush EndPoint="0.8,1" StartPoint="0.33,0">
<GradientStop Color="#FF50B3E2" Offset="0"/>
<GradientStop Color="#FF084168" Offset="1"/>
</LinearGradientBrush>
</Border.Background>
<Grid x:Name="root" >
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
……
</Grid>
</Border>
<Border x:Name="wb" CornerRadius="5" BorderThickness="3" BorderBrush="#FF1A55AA">
<Border.Background>
<LinearGradientBrush EndPoint="0.8,1" StartPoint="0.33,0">
<GradientStop Color="#FF50B3E2" Offset="0"/>
<GradientStop Color="#FF084168" Offset="1"/>
</LinearGradientBrush>
</Border.Background>
<Grid x:Name="root" >
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
……
</Grid>
</Border>
以上是窗口的大致框架。
接下来就是对最外层的Border进行剪裁，即设置它的Clip属性。

<Border x:Name="wb" CornerRadius="5" BorderThickness="3" BorderBrush="#FF1A55AA">
<Border.Background>
<LinearGradientBrush EndPoint="0.8,1" StartPoint="0.33,0">
<GradientStop Color="#FF50B3E2" Offset="0"/>
<GradientStop Color="#FF084168" Offset="1"/>
</LinearGradientBrush>
</Border.Background>
<Border.Clip>

<RectangleGeometry x:Name="r3" Rect="50,0,90,1000"/>
<RectangleGeometry x:Name="r4" Rect="360,0,160,1000"/>
</GeometryGroup>
</Border.Clip>
<Grid x:Name="root" >
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
……
</Grid>
</Border>
<Border x:Name="wb" CornerRadius="5" BorderThickness="3" BorderBrush="#FF1A55AA">
<Border.Background>
<LinearGradientBrush EndPoint="0.8,1" StartPoint="0.33,0">
<GradientStop Color="#FF50B3E2" Offset="0"/>
<GradientStop Color="#FF084168" Offset="1"/>
</LinearGradientBrush>
</Border.Background>
<Border.Clip>
<GeometryGroup FillRule="Nonzero">
<RectangleGeometry x:Name="r1" Rect="0,50,1000,100"/>
<RectangleGeometry x:Name="r2" Rect="0,220,1000,100"/>
<RectangleGeometry x:Name="r3" Rect="50,0,90,1000"/>
<RectangleGeometry x:Name="r4" Rect="360,0,160,1000"/>
</GeometryGroup>
</Border.Clip>
<Grid x:Name="root" >
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
……
</Grid>
</Border>那么，通过这四个矩形的裁剪，窗口会变成什么模样呢。看下图。
下面就是窗口的启动动画，通过对这四个矩形进行动画处理，在窗体的Loaded事件中播放动画，当动画播放完成时，再把这些Clip去掉，即设为null。

上面的资源中，包含两个动画，后面一个是窗口关闭时的动画。
另外，我们的窗口还需要两个小按钮，就是标题栏上方的“最小化”和“关闭”按钮，用Button即可，不过我们要为Button类自定义一下控件模板。

由于这些小按钮都比较相似，因此，我们先定义一个通用的样式captionButtonStyle，而后的minCaptionButtonStyle和closeCaptionButtonStyle都是基于这个样式的。
注意按钮的字体要使用Segoe UI Symbol，这样我们可以通过编号来引用一些特殊符号，如关闭按钮上的 X 。
下面我们回到主窗体，现在我把整个代码贴出来。

在X按钮点击时，我们不是直接Close窗口，因为我们还要关闭动画，所以，单击X按钮时播放关闭动画，当动画结束时，才把窗口真正关掉。

好的，现在来看看这个窗口动画吧。
下图是窗口启动时的动画。
下图是窗体关闭时的动画。窗体一边旋转，一边缩小，一边淡出，直到消失。
