如何在托管C++中正确实现带事件的C#接口

public interface IEventInterface
{
    event EventHandler MyEvent;
    void TriggerEvent();
}

#include <vcclr.h>

using namespace System;

public ref class ManagedClass : public IEventInterface
{
public:
    virtual event EventHandler^ MyEvent;

    virtual void TriggerEvent()
    {
        MyEvent(this, EventArgs::Empty);
    }
};

class Program
{
    static void Main(string[] args)
    {
        IEventInterface managedClass = new ManagedClass();
        managedClass.MyEvent += MyEventHandler;

        managedClass.TriggerEvent();
    }

    static void MyEventHandler(object sender, EventArgs e)
    {
        Console.WriteLine("Event triggered!");
    }
}
