我在C#中定义了两个接口,如下所示:

[Guid("4938540B-3DB2-452c-A061-59EC499657E7")]
[InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IRADevice
{
   Void FA();
}

/// <summary>
/// IRADevice interface represents a given RADevice.
/// </summary>
[Guid("4938540B-3DB2-452c-A061-59EC499657E8")]
[InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IRADevice2 : IRADevice
{
    void FB();
}

在c ++代码中,我使用以下命令导入上面接口生成的tlb

#import "device.tlb"  raw_interfaces_only

创建的tlh文件如下:

struct __declspec(uuid("4938540b-3db2-452c-a061-59ec499657e7"))
IRADevice : IDispatch
{
//
// Raw methods provided by interface
//

virtual HRESULT __stdcall FA ( ) = 0;
};

struct __declspec(uuid("4938540b-3db2-452c-a061-59ec499657e8"))
IRADevice2 : IDispatch
{
//
// Raw methods provided by interface
//

virtual HRESULT __stdcall FB ( …
