WPF TreeView绑定字典集合

  <TreeView Name="Tree" HorizontalAlignment="Left"  Height="269"  Width="292" >
           
            <TreeView.ItemTemplate>
                <HierarchicalDataTemplate ItemsSource="{Binding Value}">
                    <StackPanel>
                        <TextBlock  Text="{Binding Key.DepartmentName}" Background="Red" />
                    </StackPanel>
                    
                    <HierarchicalDataTemplate.ItemTemplate>
                        <HierarchicalDataTemplate>
                            <TextBlock Text="{Binding Path=ParsonName}"/>
                        </HierarchicalDataTemplate>
                    </HierarchicalDataTemplate.ItemTemplate>
                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>

 Key为实体类，Valuey也是实体类,ParsonName是Value集合的实体类字段
