我有一个文件夹，并包含多个文件夹，每个文件夹都有一个名为Package的xml文件。 我想创建一个树视图。 所以必须看看Treeview enter image description here
XML frist文件结构：

请尝试以下代码。我使用了xml linq和一个比你的代码简单得多的递归算法。

namespace TreeView_Test
{
class Program
{
static AutoResetEvent autoEvent = new AutoResetEvent(false);
[STAThread]
static void Main(string[] args)
{
MainWindow window = new MainWindow();
window.ShowDialog();
autoEvent.WaitOne();
}
}
public partial class MainWindow : Window
{
private TreeViewItem tree; // TreeViewItem reference
private TreeView xmlTreeView = new TreeView();
const string FILENAME1 = @"c:\temp\test1.xml";
const string FILENAME2 = @"c:\temp\test2.xml";
public MainWindow()
{
InitializeComponent();
this.Loaded +=new RoutedEventHandler(Window_Loaded);
}
private void InitializeComponent()
{
this.AddChild(xmlTreeView);
this.Activate();
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
tree = new TreeViewItem(); // instantiate TreeViewItem
tree.Header = "Projekt"; // assign name to TreeViewItem
xmlTreeView.Items.Add(tree); // add TreeViewItem to TreeView
XDocument doc = XDocument.Load(FILENAME1);
XElement element = (XElement)doc.FirstNode;
BuildTree(element, tree); // build node and tree hierarchy
doc = XDocument.Load(FILENAME2);
element = (XElement)doc.FirstNode;
BuildTree(element, tree); // build node and tree hierarchy
}
private void BuildTree(XElement element, TreeViewItem treeViewItem)
{
// TreeViewItem to add to existing tree
TreeViewItem newNode = new TreeViewItem();
treeViewItem.Items.Add(newNode);
newNode.Header = element.Name.LocalName;
if (!element.HasElements)
{
TreeViewItem newText = new TreeViewItem();
newNode.Items.Add(newText);
newText.Header = element.Value;
}
else
{
foreach (XElement child in element.Elements())
{
BuildTree(child, newNode);
}
}
}
}

其实我不使用treeview类。但我可以建议如何阅读ml文件。
class Object
{
public string Type { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public string Language { get; set; }
List<Object> Objects { get; set; }
}
class ObjectFinder
{
private XElement xmlContent;
public ObjectFinder(string filePath)
{
xmlContent = XElement.Load(filePath);
}
public List<Object> Objects()
{
List<Object> list = new List<Object>();
return xmlContent.Elements().Select(obj =>
{
return new Object
{
Description = obj.Attribute("Description").Value,
Language = obj.Attribute("Language").Value,
Name = obj.Value,
Type = obj.Attribute("Type").Value
};
}).ToList();
}
}
类的用法;
ObjectFinder objectFinder = new ObjectFinder("filePath");
List<Object> list = objectFinder.Objects();
阅读最顶层文件后，您可以阅读其他文件并将其附加到相关的对象中。如果您无法成功，请告诉我们
