如何将函数的这个地址从C++写入C#？

Question

我正在学习DirectX,但我不太了解C++所以我决定使用SharpDX.但我在C++中坚持使用TypedEventHandler中的函数地址,但是我不知道如何在C#中编写它？有人可以帮忙吗？

ref class App sealed : public IFrameworkView
{
public:
virtual void Initialize(CoreApplicationView^ AppView)
{
    AppView->Activated += ref new TypedEventHandler
        <CoreApplicationView^, IActivatedEventArgs^>(this, &App::OnActivated);
}
virtual void SetWindow(CoreWindow^ Window) {}
virtual void Load(String^ EntryPoint) {}
virtual void Run() {}
virtual void Uninitialize() {}

void OnActivated(CoreApplicationView^ CoreAppView, IActivatedEventArgs^ Args)
{
    CoreWindow^ Window = CoreWindow::GetForCurrentThread();
    Window->Activate();
}
};

到目前为止我的转换

internal class App : IFrameworkView
{
    public void Initialize(CoreApplicationView AppView)
    {
        // Call OnActivated() when the Activated event is triggered
        AppView.Activated += new TypedEventHandler<CoreApplicationView, IActivatedEventArgs>(this,this.OnActivated);

    }
    public void SetWindow(CoreWindow Window) {}
    public void Load(String EntryPoint) {}
    public void Run() {}
    public void Uninitialize() {}

    public void OnActivated(CoreApplicationView CoreAppView, IActivatedEventArgs Args)
    {
        CoreWindow Window = CoreWindow.GetForCurrentThread();
        Window.Activate();
    }

}

对于C#事件连线,您不需要"this"参数:

public sealed class App : IFrameworkView
{
    public virtual void Initialize(CoreApplicationView AppView)
    {
        AppView.Activated += new TypedEventHandler <CoreApplicationView, IActivatedEventArgs>(OnActivated);
    }

    public virtual void SetWindow(CoreWindow Window)
    {
    }
    public virtual void Load(string EntryPoint)
    {
    }
    public virtual void Run()
    {
    }
    public virtual void Uninitialize()
    {
    }

    public void OnActivated(CoreApplicationView CoreAppView, IActivatedEventArgs Args)
    {
        CoreWindow Window = CoreWindow.GetForCurrentThread();
        Window.Activate();
    }
}
