private delegate void ValidateEvent(int eventCode);

        private static void ValidateEventCallback(int eventCode)
        {
            Debug.Print("Validate Event:" + eventCode.ToString());
        }

c++

typedef void ( *CPPCallback )(
    int eventCode);

STDMETHODIMP CValidator::ValidateEvent(int procAddress)
{
    // TODO: 在此添加实现代码

    this->validateEventProc = (CPPCallback)procAddress;
    return S_OK;
}

传入：

var method = new ValidateEvent(ValidateEventCallback);
var methodAddress = Marshal.GetFunctionPointerForDelegate(method);
securityValidator.ValidateEvent(methodAddress.ToInt32());
