手動提高ContextMenuClosing事件

Question

我從ContextMenu派生並派生類內部我需要手動提高ContextMenuClosing事件。我嘗試以下兩種方式：

// 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()); 

我是新來RoutedEvents，有人可以幫我如何手動提升的ContextMenuClosing事件？謝謝！
