窗口中的所有Button对象都将受到这个Style的影响，从而文本变成统一的蓝色CourierNew字体:

<Window.Resources>

<Style TargetType="Button">

<Setter Property="Foreground" Value="Blue"/>

<Setter Property="FontFamily" Value="CourierNew"/>

</Style>

</Window.Resources>

<Grid ShowGridLines="True">

<Grid.ColumnDefinitions>

<ColumnDefinition  Width="50*"/>

<ColumnDefinition Width="50*" />

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition  Height="25*"/>

<RowDefinition  Height="25*"/>

<RowDefinition  Height="25*"/>

</Grid.RowDefinitions>

<Button Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="0" Grid.RowSpan="1">button1</Button>

<Button Grid.Column="2" Grid.ColumnSpan="1" Grid.Row="1" Grid.RowSpan="1">button2</Button>

</Grid>

结果图：

 

添加x:key

<Window.Resources>

<Style TargetType="Button" x:Key="ButtonStyle">

<Setter Property="Foreground"  Value="Blue"/>

<Setter Property="FontFamily" Value="CourierNew"/>

</Style>

</Window.Resources>

<Grid ShowGridLines="True">

<Grid.ColumnDefinitions>

<ColumnDefinition  Width="50*"/>

<ColumnDefinition Width="50*" />

</Grid.ColumnDefinitions>

<Grid.RowDefinitions>

<RowDefinition  Height="25*"/>

<RowDefinition  Height="25*"/>

<RowDefinition  Height="25*"/>

</Grid.RowDefinitions>

<Button Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="0" Grid.RowSpan="1">normal button</Button>

<Button Grid.Column="1" Grid.ColumnSpan="1" Grid.Row="1" Grid.RowSpan="1" Style="{StaticResource ButtonStyle}">styled button1</Button>

<Button Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="2" Grid.RowSpan="1" Style="{StaticResource ButtonStyle}">styled button2</Button>

</Grid>

BaseOn继承属性值

<Window.Resources>

        <Style TargetType="Button" x:Key="ButtonStyle">

            <Setter Property="Foreground"  Value="Blue"/>

            <Setter Property="FontFamily" Value="CourierNew"/>

        </Style>

        <Style TargetType="Button" x:Key="TriggerButtonStyle" BasedOn="{StaticResource ButtonStyle}">

            <Style.Triggers>

                <Trigger  Property="IsPressed" Value="True">

                    <Setter Property="Foreground" Value="Red"/>

                </Trigger>

            </Style.Triggers>

        </Style>

    </Window.Resources>

    <Grid ShowGridLines="True">

        <Grid.ColumnDefinitions>

            <ColumnDefinition  Width="50*"/>

            <ColumnDefinition Width="50*" />

        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions>

            <RowDefinition  Height="25*"/>

            <RowDefinition  Height="25*"/>

            <RowDefinition  Height="25*"/>

        </Grid.RowDefinitions>

        <Button Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="0" Grid.RowSpan="1">normal button</Button>

        <Button Grid.Column="1" Grid.ColumnSpan="1" Grid.Row="1" Grid.RowSpan="1" Style="{StaticResource ButtonStyle}">styled button1</Button>

        styled button2字体颜色与字体是继承与ButtonStyle

        <Button Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="2" Grid.RowSpan="1" Style="{StaticResource TriggerButtonStyle}">styled button2</Button>

    </Grid>
