Windows.Ui.Xaml.Controls.Primitives.ButtonBase无法显式调用operator或accessor

错误发生在以下代码中：

 case 11:
                {
                    ButtonBase buttonBase2 = (ButtonBase)target;
                    WindowsRuntimeMarshal.AddEventHandler<RoutedEventHandler>(new Func<RoutedEventHandler, EventRegistrationToken>(buttonBase2, ButtonBase.add_Click), new Action<EventRegistrationToken>(buttonBase2, ButtonBase.remove_Click), new RoutedEventHandler(this.RemoveTrack));
                    break;
                }

Answer 1

这是编译时错误。来自MSDN WindowsRuntimeMarshal.AddEventHandler Method：

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

如果要向Click事件添加/删除事件处理程序，请使用+= and -= operators

buttonBase2.Click += this.RemoveTrack;

和

buttonBase2.Click -= this.RemoveTrack;
