一:{Binding ElementName=grid0, Path=Height}

ElementName=grid0:查找到名为grid0的控件。

, Path=Height:获取名为grid0的控件的Height属性值。

即:Lb1的属性值设置为grid0控件的Height属性设置值。

    <Grid Name="grid0">
        <Grid>
            <StackPanel Background="AliceBlue">
                <Border HorizontalAlignment="Left" Height="30" Cursor="Hand" Panel.ZIndex="2">
                    <Label Content="返回" HorizontalAlignment="Left" MouseLeftButtonUp="Label_MouseLeftButtonUp"></Label>
                </Border>
                <Border VerticalAlignment="Top" Margin="0,-30,0,0">
                    <Label name="Lb1" Content="123" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="{Binding ElementName=grid0, Path=Height}" FontSize="28" FontFamily="微软雅黑"></Label>
                </Border>
            </StackPanel>
        </Grid>
    </Grid>

 二: {StaticResource LabelPanelStyle}

x:key属性值等于LabelPanelStyle的且类型为Lable的样式,加载到当前样式(Lable)中

<UserControl.Resources>
  <Style x:Key="LabelPanelStyle" TargetType="{x:Type Label}">
      <Setter Property="Foreground" Value="White"/>
  </Style>
</UserControl.Resources>
<Grid>
    <Label x:Name="borderControl"  FontFamily="微软雅黑" FontSize="20"  Background="#FF62A0CA" Content="123"  Style="{StaticResource LabelPanelStyle}"></Label>
</Grid>
