computed计算属性，你值得拥有
或者，写点击事件，筛选出所有的选中的行数据，第二张图渲染总数就可以了

wpf里ListView怎么设置选中行的颜色

我想让选中的那一行显示为蓝色，其他未选中的颜色不变，最好是在鼠标经过某一行时也能显示特定的颜色。wpf中ListView本来是自带这样的效果的，但是我想让显示效果扁平一些，所以想更改一下效果，找了好久都不太对，求大神指教，急

用触发器控制，代码如下~
<Style TargetType="x:Type ListBoxItem">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="x:Type ListBoxItem">
        <Border Background="TemplateBinding Background"
            BorderBrush="TemplateBinding BorderBrush"
            BorderThickness="TemplateBinding BorderThickness">
          <ContentPresenter />
        </Border>
        <ControlTemplate.Triggers>
          <Trigger Property="IsMouseOver" Value="True"><!--鼠标悬停-->
            <Setter Property="Background" Value="#FFDCDCDC"/><!--value中写你要的颜色的值-->
          </Trigger>
          <Trigger Property="IsSelected" Value="true"><!--选中-->
            <Setter Property="Background" Value="#FF0078E6"/>
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>
