我有一个包含三个实体的场景:

#pragma  once
public interface class INativeWindow
{
    void Nothing();
};

#pragma  once
ref class NWHolder;
public ref class CLINativeWindow : System::Windows::Forms::NativeWindow, INativeWindow
{
public:
    NWHolder^ Parent;
    virtual void  Nothing() sealed;
    void DoIt();
};

#include "stdafx.h"
#include "CLINativeWindow.h"

void CLINativeWindow::Nothing()
{
    Console::Write("None");
}
void CLINativeWindow::DoIt()
{
    Parent->KeyDown(this, nullptr);
};

#pragma  once
#include "INativeWindow.h"
#include "CLINativeWindow.h"

public ref class NWHolder
{

internal:
    event System::Windows::Forms::KeyEventHandler^ KeyDown;
public:
    virtual property INativeWindow^ OwnNativeWindow
    {
        INativeWindow^ __clrcall get() sealed;
        void __clrcall set(INativeWindow^ value) sealed; 
    }

private:
    CLINativeWindow^ nativeWindow_;
};

#include "stdafx.h"
#include "NWHolder.h"


INativeWindow^ NWHolder::OwnNativeWindow::get()
{
    return nativeWindow_;
}

void NWHolder::OwnNativeWindow::set(INativeWindow^ value)
{
    nativeWindow_ = dynamic_cast<CLINativeWindow^>(value); 
}

最佳答案

C++/CLI 事件的“raise”内部方法总是声明为 protected 。在 NWHolder 上添加一个名为“FireKeyDownEvent”的方法，并为其提供您喜欢的任何可访问性。
