c# - 从循环列表中查找父类

Question

我有一个像下面这样的课，

public class Folder : BindableBase
{
    private string name;
    public string Name
    {
        get { return name; }
        set { name = value;  }
    }
    private List<Folder> subfolders=new List<Folder>();
    public List<Folder> Folders
    {
        get { return subfolders; }
        set{ subfolders= value; }
    }
}

此类绑定(bind)到 TreeView HierarchicalDataTemplate当我从 TreeView 中选择任何节点时我会得到 SelectedItem如 Folder class object .我如何找到 SelectedItem 的父类在 View Model .

分层数据模板

  <HierarchicalDataTemplate x:Key="Folders" ItemsSource="{Binding Folders}" >
        <StackPanel Orientation="Horizontal">                
            <TextBlock Foreground="Black" Text="{Binding Name}" />
        </StackPanel>
  </HierarchicalDataTemplate>

这些属性将冒泡并暴露出来，因为这就是 C# 继承的工作方式。只需直接绑定(bind)到基本属性，就好像它们存在于文件夹中一样。

public class BindableBase
{
    public string InheritedName { get; set; }
}

public class Folder : BindableBase
{
    private string name;
    public string Name
    {
        get { return name; }
        set { name = value;  }
    }
    private List<Folder> subfolders=new List<Folder>();
    public List<Folder> Folders
    {
        get { return subfolders; }
        set{ subfolders= value; }
    }
}

XAML:

<TextBlock Foreground="Black" Text="{Binding InheritedName}" />
