1、設定事件繫結到函式TreeUAAddressSpace_SelectedItemChanged

 this.treeBrowseUASpace.SelectedItemChanged += new System.Windows.RoutedPropertyChangedEventHandler<object>(this.TreeUAAddressSpace_SelectedItemChanged);

2、繫結的響應函式如下：

 private void TreeUAAddressSpace_SelectedItemChanged(object sender, EventArgs e)
        {
            TreeViewItem treeValue = (TreeViewItem)treeBrowseUASpace.SelectedItem;

}

3、注：這裡的樹為TreeView treeBrowseUASpace;

      TreeViewItem treeValue即為當前選中的節點的值

4、顯示到介面上

       首先設定一個stackpanel控制元件(拖到介面上就行),classInstance為樹所在的類的物件

 PanelUAAddressSpace.Children.Add(classInstance.treeBrowseUASpace);
