wpf TreeView通过ItemSource设置的数据源。通过获取SelectItem时结果是实体类。怎么更改为TreeViewItem

Answer 1

XAML：

<TreeView TreeViewItem.Selected="TreeView_Selected" />

后台代码： 

private void TreeView_Selected(object sender, RoutedEventArgs e)
{
    TreeViewItem tviSelected = e.OriginalSource as TreeViewItem;
}

Answer 2

selected事件 里面的 参数e 有treeviewitem 对象 e.OriginalSource
比如说
private void treeView1_Selected(object sender, RoutedEventArgs e)
{
TreeviewItem t = e.OriginalSource as TreeViewItem;
}
这样就能获得 treeviewitem

Answer 3

YourClass yc = treeView.SelectedItem as YourClass;

Answer 4

if(e.item is TreeViewItem)
