如何通过右键单击表单上的任何元素来显示带有按钮的上下文菜单?
表单中按钮的用途是:
显示x:执行右键单击(显示上下文菜单)的控件的名称。
总结一下,我想右键单击表单上的任何元素,以1个按钮显示上下文菜单"显示我的名字"应显示消息框显示:"我的名字是[x:元素名称]"

为每种控件定义隐式Style
:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="300" Width="300">
<Window.Resources>
<ContextMenu x:Key="cm">
<MenuItem Header="Show name" Click="MenuItem_Click" />
</ContextMenu>
<Style TargetType="Button">
<Setter Property="ContextMenu" Value="{StaticResource cm}" />
</Style>
<Style TargetType="TextBox">
<Setter Property="ContextMenu" Value="{StaticResource cm}" />
</Style>
</Window.Resources>
<StackPanel>
<Button x:Name="a" Content="a" />
<TextBox x:Name="b" />
</StackPanel>
</Window>
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
MenuItem mi = sender as MenuItem;
ContextMenu cm = mi.Parent as ContextMenu;
FrameworkElement fe = cm.PlacementTarget as FrameworkElement;
MessageBox.Show(fe.Name);
}
