Silverlight使用XmlReader读取XML数据到TreeView中

以前写的了，Silverlight用的人貌似不多。

主要是使用XmlReader读取XML的Attribute数据读取到TreeViewItem的Header和DataContext中，点击TreeView节点的时候将DataContext取出来。

读取XML核心代码：

        private void LoadCameraListTree(TreeViewItem parentItem,XmlReader reader,int CurrentLevel)
        {
            CurrentLevel = CurrentLevel + 1;
            //XmlReader的ReadSubtree不光是该节点的子节点，还包括该节点本身
            //因此要跳过第一个节点
            int i = 0;
            while (reader.Read())
            {
                if (0 != i && reader.IsstartElement() && reader.HasAttributes)
                {
                    TreeViewItem item = new TreeViewItem();
                    item.Header = reader.GetAttribute("name");
                    item.DataContext = CurrentLevel.ToString() + "&" + reader.GetAttribute("Id") + "&" + reader.GetAttribute("name");
                    parentItem.Items.Add(item);
                    LoadCameraListTree(item,reader.ReadSubtree(),CurrentLevel);
                }
                if (0 == i)
                {
                    ++i;
                }
            }
        }

                XmlReader reader = XmlReader.Create("demo.xml");
                while (reader.Read())
                {
                    if (reader.IsstartElement() && reader.GetAttribute("Id") == "1")
                    {
                        int CurrentLevel = 1;
                        TreeViewItem item = new TreeViewItem();
                        item.Header = reader.GetAttribute("name");
                        item.DataContext = CurrentLevel.ToString() + "&" + reader.GetAttribute("Id") + "&" + reader.GetAttribute("name");
                        treeView_XML.Items.Add(item);
                        LoadCameraListTree(item,CurrentLevel);
                    }
                }

        private void treeView_XML_selecteditemchanged(object sender,RoutedPropertyChangedEventArgs<object> e)
        {
            TreeView view = sender as TreeView;
            TreeViewItem SelectedItem = (TreeViewItem)view.SelectedItem;
            string SelectedItem_DataContext = (string)SelectedItem.DataContext;
            textBlock_Debug.Text = SelectedItem_DataContext;

            string[] SelectedItem_Attributes = SelectedItem_DataContext.Split("&".tochararray());
            string SelectedItem_Level = SelectedItem_Attributes[0];
            textBox_Level.Text = SelectedItem_Level;

            textBox_Id.Text = SelectedItem_Attributes[1];
            textBox_name.Text = SelectedItem_Attributes[2];
        }
