推荐答案

您可以尝试使用此方法，但是对于更具体的答案，请通过一些示例详细说明您的问题.
在此示例中，我使用了一个xml文件来填充树形视图，然后获取选定的值.

you may try this but, for more specific answers please elaborate your question possibly with some examples.
In this example i have used an xml file to populate the tree view and then getting the selected value.

private void _treeView_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
       {
           if ((((System.Windows.Controls.ItemsControl)(sender)).Items).Count > 0)
           {
               string CategoryName = (((System.Xml.XmlElement)(_treeView.SelectedItem))).Attributes[0].Value;
               string Name = (((System.Xml.XmlElement)(_treeView.SelectedItem))).Attributes[1].Value;
               string Imageref = (((System.Xml.XmlElement)(_treeView.SelectedItem))).Attributes[2].Value;
}
}

也许您会从此示例中得到一些提示..

probably you may get some hint from this example..
