C++CLI 中的 ComVisible

发布于 2024-08-02 01:39:45 字数 900 浏览 4 评论 0原文

我正在将 C++ 转换为 C++/CLI，并希望将一些托管类公开为 COM 对象。在 C# 中，设置 [ComVisible] & 很容易。从接口（也是 ComVisible）继承完成了这项工作。但是，作为 C++/CLI 构建的 C++ 项目不会导出 DllRegisterServer。

这是示例项目（从 VS 2008 中的 CLR 控制台应用程序项目开始）。

#include "stdafx.h"

using namespace System;
using namespace System::Runtime::InteropServices;

[ComVisible(true)]
[Guid("E3CF8A18-E4A0-4bc3-894E-E9C8648DC1F0")]
[InterfaceType(ComInterfaceType::InterfaceIsDual)]
public interface class ITestInterface
{
    void TestMethod();
};


[ComVisible(true)]
[Guid("1514adf6-7cb0-4561-9fbb-b75c0467149b")]
public ref class CliComClass : ITestInterface
{
    public: 
        virtual void TestMethod() 
        {
        }
};

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");
    return 0;
}

当我在输出 .exe 上运行 regsvr32 时，出现错误，提示未找到 DllRegisterServer。我尝试过谷歌寻求一些帮助，但没有成功。

i'm converting C++ to C++/CLI and would like to expose some managed classes as COM objects. In C# it was easy and setting [ComVisible] & inheriting from interface (also ComVisible) did the job.
However C++ project build as C++/CLI does not export DllRegisterServer.

Here is sample project (started from CLR Console Application project in VS 2008).

#include "stdafx.h"

using namespace System;
using namespace System::Runtime::InteropServices;

[ComVisible(true)]
[Guid("E3CF8A18-E4A0-4bc3-894E-E9C8648DC1F0")]
[InterfaceType(ComInterfaceType::InterfaceIsDual)]
public interface class ITestInterface
{
    void TestMethod();
};


[ComVisible(true)]
[Guid("1514adf6-7cb0-4561-9fbb-b75c0467149b")]
public ref class CliComClass : ITestInterface
{
    public: 
        virtual void TestMethod() 
        {
        }
};

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");
    return 0;
}

When I run regsvr32 on output .exe I got error saying DllRegisterServer was not found. I've tried google for some help but with no success.
