Is there a type of object, to which I can cast both Buttons AND MenuItem objects in order to access their Tag properties?

void itemClick(object sender, EventArgs e)
{
    Control c = (Control)sender;
    MethodInvoker method = new MethodInvoker(c.Tag.ToString(), "Execute");
    method.Invoke();
}

object tag;
Button button;
MenuItem menuItem = sender as MenuItem;
if (menuItem  != null)
{
    tag = menuItem.Tag;
}
else if( (button = sender as Button) != null )
{
    tag = button.Tag;
}
else
{
    //not button nor MenuItem
}

object myControlOrMenu = sender as MenuItem ?? sender as Button;
if (myControlOrMenu == null)
// neither of button or menuitem
