WPF的樣式(Style)繼承 參考自http://www.cnblogs.com/SkyD/archive/2008/08/09/1264294.html，非常感謝。

用Style的BaseOn屬性可以實現(xiàn)WPF樣式的顯式繼承，例如，有一個基樣式：
Code
<Style?x:Key="BASE">
??????<Setter?Property="Control.Background">
??????????<Setter.Value>
?????????????<LinearGradientBrush?StartPoint="0,0"?EndPoint="1,1">
????????????????<GradientStop?Offset="0"?Color="Green"/>
????????????????<GradientStop?Offset="0.5"?Color="Blue"/>
????????????????<GradientStop?Offset="1"?Color="Red"/>
?????????????</LinearGradientBrush>
??????????</Setter.Value>
??????</Setter>
????</Style>
下面分別定義2個樣式繼承它：
Code
<Style?BasedOn="{StaticResource?BASE}"?TargetType="{x:Type?Button}">
??????<Setter?Property="BorderBrush"?Value="Red"></Setter>
????</Style>
????
????<Style?BasedOn="{StaticResource?BASE}"?TargetType="{x:Type?TextBox}">
??????<Setter?Property="BorderBrush"?Value="Black"></Setter>
????</Style>
而且還可以繼續(xù)繼承上面定義的樣式，例如對Button的樣式再次擴展：
<Style?BasedOn="{StaticResource?{x:Type?Button}}"?x:Key="NewButton"?TargetType="{x:Type?Button}">
??????<Setter?Property="Margin"?Value="10,0,0,0"></Setter>
????</Style>下面使用這些樣式：
<Grid>??
????<StackPanel?Width="250"?Height="400">
??????<Button?Height="30"></Button>
??????<TextBox?Height="30"></TextBox>
??????<Button?Style="{StaticResource?NewButton}"?Height="30"/>
????</StackPanel>
??</Grid>完整的代碼如下：
Code
<Page
??xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
??xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
??<Page.Resources>
????<Style?x:Key="BASE">
??????<Setter?Property="Control.Background">
??????????<Setter.Value>
?????????????<LinearGradientBrush?StartPoint="0,0"?EndPoint="1,1">
????????????????<GradientStop?Offset="0"?Color="Green"/>
????????????????<GradientStop?Offset="0.5"?Color="Blue"/>
????????????????<GradientStop?Offset="1"?Color="Red"/>
?????????????</LinearGradientBrush>
??????????</Setter.Value>
??????</Setter>
????</Style>

????<Style?BasedOn="{StaticResource?BASE}"?TargetType="{x:Type?Button}">
??????<Setter?Property="BorderBrush"?Value="Red"></Setter>
????</Style>
????
????<Style?BasedOn="{StaticResource?BASE}"?TargetType="{x:Type?TextBox}">
??????<Setter?Property="BorderBrush"?Value="Black"></Setter>
????</Style>
????
????<Style?BasedOn="{StaticResource?{x:Type?Button}}"?x:Key="NewButton"?TargetType="{x:Type?Button}">
??????<Setter?Property="Margin"?Value="10,0,0,0"></Setter>
????</Style>
??</Page.Resources>
??<Grid>??
????<StackPanel?Width="250"?Height="400">
??????<Button?Height="30"></Button>
??????<TextBox?Height="30"></TextBox>
??????<Button?Style="{StaticResource?NewButton}"?Height="30"/>
????</StackPanel>
??</Grid>
</Page>運行后的效果如下圖：
