对于你的问题，假设所有的孩子都是相同的类型.. 只需在你的窗口资源中定义一个 HierarchicalDataTemplate 任何 x:key 并放置 DataType 这是你的 Child 对象的类型......你的整个树将填充..

For your problem, assuming all the childs are of same type.. just define one HierarchicalDataTemplate in your window's resources without any x:key and put the DataType which is type of your Child object...Your whole tree will populate..

<HierarchicalDataTemplate DataType="{local:YourParentType}"
                              ItemsSource="{Binding Childs}">
    <CheckBox IsChecked="{Binding isChecked}" Content="{Binding naam}" />
</HierarchicalDataTemplate>


<HierarchicalDataTemplate DataType="{local:YourChildType}" 
                          ItemsSource="{Binding Childs}">
    <CheckBox IsChecked="{Binding isChecked}" Content="{Binding naam}" />
</HierarchicalDataTemplate>

这里假设 local 是定义您的 Child 类的命名空间 (xmlns)

here assuming local is the namespace (xmlns) in which your Child class is defined
