Question

我想创建动态树结构，我有一些红色的教程，但我不能正确。我的wpf treeview只显示了根元素。我做错了什么？

这是MainWindow：

<Window x:Class="test.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:test"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
  <Grid>
    <TreeView Name="tv" ItemsSource="{Binding}">
      <TreeView.ItemTemplate>
        <HierarchicalDataTemplate DataType="{x:Type local:Leaf}"
                                  ItemsSource="{Binding Childs}">            
          <TextBlock Text="{Binding Path=Name}" />
        </HierarchicalDataTemplate>
      </TreeView.ItemTemplate>
    </TreeView>
  </Grid>
</Window>

这是我的节点类

class Leaf
{
    public string Name { get; set; }
    public string Address { get; set; }
    public string Access { get; set; }
    public string Type { get; set; }
    public object Value { get; set; }
    public List<Leaf> Childs;

    public Leaf()
    {
        this.Name = "default";
        this.Childs = new List<Leaf>();
    }
}

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        List<Leaf> mainlist = new List<Leaf>();

        Leaf one = new Leaf();
        one.Name = "one";

        var two = new Leaf();
        two.Name = "two";

        one.Childs.Add(two);

        mainlist.Add(one);

        tv.DataContext = mainlist;
    }
}

好的，看起来Leaf of Leafs应该是这样的：

public List Childs {get;设置;}

问题解决了，抱歉对不起。
