WPF系列:样式

　　一般简单的样式我们可以直接写在控件中

<Button Canvas.Left="20" Canvas.Top="30" Width="100" Height="120" Content="A"/>

　　也可以通过Style属性定义该系列控件的样式

 <Style TargetType="{x:Type Button}">   <Setter Property="Background" Value="Green"></Setter>   <Setter Property="FontSize" Value="24" ></Setter> </Style>

　　然后通过键值，可以赋予该系列某一类型特定的样式，这个有点像CSS里的class

  <Style x:Key="ButtonMenu">    <Setter Property="Button.Background" Value="Red"></Setter>    <Setter Property="Button.Width" Value="100"></Setter>    <Setter Property="Button.Height" Value="100"></Setter>    <Setter Property="Button.FontSize" Value="24" ></Setter>  </Style>

　　WPF中的样式还可以通过BasedOn属性继承样式

 <Style x:Key="ButtonTitle" BasedOn="{StaticResource ButtonMenu}" TargetType="Button">   <Setter Property="Background">     <Setter.Value>       <LinearGradientBrush>         <GradientStop Offset="0.2" Color="LightBlue"></GradientStop>         <GradientStop Offset="0.5" Color="Blue"></GradientStop>         <GradientStop Offset="0.9" Color="DarkBlue"></GradientStop>       </LinearGradientBrush>     </Setter.Value>   </Setter>   <Setter Property="Button.Width" Value="100"></Setter>   <Setter Property="Button.Height" Value="100"></Setter> </Style>

　　最后把所有代码合在一起

  <Canvas>    <Canvas.Resources>      <Style TargetType="{x:Type Button}">        <Setter Property="Background" Value="Green"></Setter>        <Setter Property="FontSize" Value="24" ></Setter>      </Style>      <Style x:Key="ButtonMenu">        <Setter Property="Button.Background" Value="Red"></Setter>        <Setter Property="Button.Width" Value="100"></Setter>        <Setter Property="Button.Height" Value="100"></Setter>        <Setter Property="Button.FontSize" Value="24" ></Setter>      </Style>      <Style x:Key="ButtonTitle" BasedOn="{StaticResource ButtonMenu}" TargetType="Button">        <Setter Property="Background">          <Setter.Value>            <LinearGradientBrush>              <GradientStop Offset="0.2" Color="LightBlue"></GradientStop>              <GradientStop Offset="0.5" Color="Blue"></GradientStop>              <GradientStop Offset="0.9" Color="DarkBlue"></GradientStop>            </LinearGradientBrush>          </Setter.Value>        </Setter>      </Style>    </Canvas.Resources>    <Button Canvas.Left="20" Canvas.Top="30" Width="100" Height="120" Content="A"/>    <Button Canvas.Left="150" Canvas.Top="30" Style="{StaticResource ButtonMenu}" Content="B" />    <Button Canvas.Left="280" Canvas.Top="30" Style="{StaticResource ButtonTitle}" Content="C" />  </Canvas>
