C# 从WPF树视图中获取所选文本

我在WPF中显示一个树视图，如下所示

<TreeView Height="332" Background="Transparent" BorderBrush="White" HorizontalAlignment="Left" Margin="0,46,0,0" Name="treeView1" VerticalAlignment="Top" Width="182" MouseDoubleClick="treeView1_MouseDoubleClick" SelectedItemChanged="treeView1_SelectedItemChanged">

        <TreeViewItem >
            <TreeViewItem.Header>
                <StackPanel Orientation="Horizontal">
                    <Image Source="../Images/Logos/Gway.png" Height="24" Width="24"></Image>
                    <Label Content="Gway"></Label>
                </StackPanel>
            </TreeViewItem.Header>

            <!-- Child Item -->

            <TreeViewItem>
                <TreeViewItem.Header>
                    <StackPanel Orientation="Horizontal">

请帮帮我。

因为它是树状视图项目，所以它下面有一棵树，所以它不仅仅是一个简单的文本，所以为了获取内容，您可以参考以下内容并使用任何适合您需要的方法

• 显示标题的TreeViewItem的Header属性（仅当设置时）
• 用于检索以下集合绑定的ItemsSource属性
• DataContext用于检索绑定到它的数据（将其强制转换为适当的类型）并检索所需的值

是否要获取标签和图像值？

private void treeView1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
        object s = e.Source;

        TreeView obj = (TreeView) s;

        TreeViewItem item2 =(TreeViewItem)obj.SelectedItem;// item2 doesnt have any selctedText/ value property


    }
