TreeView WPF绑定

Question

我正在使用TreeView WPF 我有以下课程：

class MyFiles : INotifyPropertyChanged
{
     public event PropertyChangedEventHandler PropertyChanged;
     public string displayName;
     public string fullPath;

     public string DisplayName
     {
         get{return displayName;}
         set{displayName = value; INofityPropertyChanged();}
     }
      public string FullName
     {
         get{return fullPath;}
         set{fullPath = value; INofityPropertyChanged();}
     }

     private void INofityPropertyChanged(string propertyName="")
     {
        if(propertyName != null && PropertyChanged != null)
             PropertyChanged (this, new PropertyChangedEventsArgs(propertyName);
     }
}

我想将类绑定到TreeView 我尝试了什么：

<TreeView Name=treeViewFiles>
    <TreeView.Resources>
            <HierarcjocalDataTemplate DataType="x:Static local:MyFiles" ItemSource="{Binding MyFiles}">
                <StackPanel Orientation="Horizontal">
                    <TextBlock Text={Binding DisplayName}>
                    <TextBlock Text={Binding FullName}>
                </StackPanel>
            </HierarcjocalDataTemplate>
    <TreeView.Resources>
</TreeView>

的.cs：

fileList = new ObservableCollection<MyFiles>();
fileList.Add(new MyFiles("Test","TestPath"));
treeViewFiles.ItemSource = fileList;

我得到的东西就像一个列表而不是树：\\ 我如何修复我的代码以获得一个真正的树与root等？ 谢谢！
