WPF 可以自定义字段的Treeview

        <TreeView x:Name="tvProperties" Width="250" Padding="0" Margin="20.5,8,20.5,-8" BorderThickness="1">            <TreeView.ItemTemplate>                <HierarchicalDataTemplate DataType="{x:Type local:PropertyNodeItem}" ItemsSource="{Binding Children}">                    <StackPanel Orientation="Horizontal">                        <StackPanel.ToolTip>                            <TextBlock VerticalAlignment="Center" Text="{Binding Name}" TextWrapping="Wrap" MaxWidth="200" />                        </StackPanel.ToolTip>                        <Image VerticalAlignment="Center" Source="{Binding Icon}" Width="16" Height="16" Margin="0,0,2,2"/>                        <TextBlock VerticalAlignment="Center" Text="{Binding DisplayName}"/>                        <Image VerticalAlignment="Center" Source="{Binding EditIcon}" Width="16" Height="16" Margin="2,0,0,0"/>                    </StackPanel>                </HierarchicalDataTemplate>            </TreeView.ItemTemplate>        </TreeView>
