Question

wpf 怎么为label 添加 图标？

Answer 1

直接定义在控件中，如下：

<Label Width="200" Height="100">

<Label.Content>

<DockPanel>

<Image Source="logo.png" Width="20" Height="20" DockPanel.Dock="Left"/>

<TextBlock Text="33333333333" DockPanel.Dock="Right" />

</DockPanel>

</Label.Content>

</Label>

 

在样式中定义如下：

• <Style x:Key="LabelStyle1" TargetType="{x:Type Label}">
              <Setter Property="Template">
                  <Setter.Value>
                      <ControlTemplate TargetType="{x:Type Label}">
                          <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                              <DockPanel>
                                  <Image Source="logo.png" Width="20" Height="20" DockPanel.Dock="Left"/>
                                  <ContentPresenter DockPanel.Dock="Right" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                              </DockPanel>
                             </Border>
                          <ControlTemplate.Triggers>
                              <Trigger Property="IsEnabled" Value="false">
                                  <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                              </Trigger>
                          </ControlTemplate.Triggers>
                      </ControlTemplate>
                  </Setter.Value>
              </Setter>
          </Style>

为什么在设计器里面可以看到 但一运行就看不到了

追答

你的图片资源属性没有配置正确。
在图片资源属性中配置
Build Aciton和Copy to Output Directory；
前者你配置成Content，后者配置为Copy always 或者 Copy if newer;
这样会在编译后的输出多一张图片。

当然你也可以将图片作为资源编译到exe中。
