在尝试找出所需的代码后,我认为值得在这里发布最终版本
C++/CX
//.h
[Windows::Foundation::Metadata::WebHostHidden]
public interface class ICallback
{
public:
virtual void Exec( Platform::String ^Command, Platform::String ^Param);
};
//.cpp
ICallback ^CSCallback = nullptr;
void Direct3DInterop::SetCallback( ICallback ^Callback)
{
CSCallback = Callback;
}
//...
if (CSCallback != nullptr)
CSCallback->Exec( "Command", "Param" );
C#
public class CallbackImpl : ICallback
{
public void Exec(String Command, String Param)
{
//Execute some C# code, if you call UI stuff you will need to call this too
//Deployment.Current.Dispatcher.BeginInvoke(() => {
// //Lambda code
//}
}
}
//...
CallbackImpl CI = new CallbackImpl();
D3DComponent.SetCallback( CI);
