Vortice.Windows:如何在WinUI中调用SetSwapChain()？
Vortice.Windows:如何在WinUI中调用SetSwapChain()？
提问于 2022-07-07 00:02:58
我正在尝试通过调用SwapChainPanel (调用ISwapChainPanelNative.SetSwapChain() )来初始化在文件中所描述的在文件中。
但是，我很难将我的Microsoft.UI.Xaml.Controls.SwapChainPanel转换为ISwapChainPanelNative。
我怎样才能从我的ISwapChainPanelNative WinUI SwapChainPanel得到一个
到目前为止我尝试过的是：
private void AssociateSwapChainPanel(
Microsoft.UI.Xaml.Controls.SwapChainPanel swapChainPanel,
Vortice.DXGI.IDXGISwapChain3 swapChain)
{
IUnknown swapChainPanelUnknown = swapChainPanel as IUnknown; // null
IInspectable swapChainPanelInspectable = swapChainPanel as IInspectable; // null
var swapChainPanelNative = swapChainPanel as Vortice.WinUI.ISwapChainPanelNative; // Doesn't compile
var swapChainPanelNative = swapChainPanelInspectable.ObjRef.AsInterface<Vortice.WinUI.ISwapChainPanelNative>(); // Exception
var swapChainPanelNative = WinRT.CastExtensions.As<Vortice.WinUI.ISwapChainPanelNative>(swapChainPanel); // Exception
var swapChainPanelNative = (Vortice.WinUI.ISwapChainPanelNative)(object)swapChainPanel; // Exception回答 1
