c# wpf怎么在图片上加个label

添加一个Gird

Gird中添加一个label，位置你自己设；

Grid的Background设为该图片，ImageBrush，你自己查查吧；

至于margin随时变化，怎么个变法，你没说清，必要时可以后台代码 *** 作。

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>

1.使用绝对坐标

<Canvas>

    <Label Content="..." Width="60" Height="25" Canvas.Left="50" Canvas.Top="50" />

</Canvas>

2.使用 Grid

<Grid>

    <Grid.ColumnDefinitions>

        <ColumnDefinition Width="50" />

        <ColumnDefinition />

    </Grid.ColumnDefinitions>

    <Grid.RowDefinitions>

        <RowDefinition Height="50" />

        <RowDefinition />

    </Grid.RowDefinitions>

    <Label Content="..." Width="60" Height="25" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Left" VerticalAlignment="Top" />

</Grid>

方法多多
