手动引发 ContextMenuClosing 事件
我从 ContextMenu 派生，在派生类中我需要手动引发 ContextMenuClosing 事件。我尝试了以下两种方法：
// On runtime tells me it can't convert from
// "System.Windows.RoutedEventArgs" to
// "System.Windows.Controls.ContextMenuEventArgs"
RaiseEvent(new RoutedEventArgs(ContextMenuClosingEvent));
// Second attempt: On compile time tells me,
// there's no constructor for ContextMenuEventArgs
OnContextMenuClosing(new ContextMenuEventArgs());
我是 RoutedEvents 的新手，有人可以帮助我如何手动引发 ContextMenuClosing 事件吗？谢谢！
I'm deriving from ContextMenu and inside the derived class I need to raise the ContextMenuClosing event manually. I tried the following two ways:
// On runtime tells me it can't convert from
// "System.Windows.RoutedEventArgs" to
// "System.Windows.Controls.ContextMenuEventArgs"
RaiseEvent(new RoutedEventArgs(ContextMenuClosingEvent));
// Second attempt: On compile time tells me,
// there's no constructor for ContextMenuEventArgs
OnContextMenuClosing(new ContextMenuEventArgs());
I'm new to RoutedEvents, can someone please help me how to raise the ContextMenuClosing event manually? Thanks!

在这个问题中，海报显示了他似乎能够使用的代码实例化 ContextMenuEventArgs，即使它的构造函数是私有的
In this question the poster shows code in which he seems to be able to instantiate ContextMenuEventArgs even though its constructor is private
