我有一个d3dDevice：
ComPtr<ID3D11Device1>d3dDevice;我在这里用它做dxgiDevice：
ComPtr<IDXGIDevice3> dxgiDevice2;
HRESULT hr;
hr = d3dDevice.As( &dxgiDevice2 ); // S_OK
hr = d2dFactory->CreateDevice( dxgiDevice2.Get(), d2dDevice.GetAddressOf() ); // E_INVALIDARG One or more arguments are invalid
hr = d2dDevice->CreateDeviceContext(
D2D1_DEVICE_CONTEXT_OPTIONS_NONE,
&d2dDeviceContext
);为什么运行时会发生此错误？

问题是，您还没有创建与DX11兼容的Direct2D设备。您需要传递正确的创建标志，还应该考虑定义所需的功能级别。类似于：
// This flag adds support for surfaces with a different color channel
// ordering than the API default.
// You need it for compatibility with Direct2D.
UINT creationFlags = D3D11_CREATE_DEVICE_BGRA_SUPPORT;
// This array defines the set of DirectX hardware feature levels this
// app supports.
// The ordering is important and you should preserve it.
// Don't forget to declare your app's minimum required feature level in its
// description. All apps are assumed to support 9.1 unless otherwise stated.
D3D_FEATURE_LEVEL featureLevels[] =
{
D3D_FEATURE_LEVEL_11_1,
D3D_FEATURE_LEVEL_11_0,
D3D_FEATURE_LEVEL_10_1,
D3D_FEATURE_LEVEL_10_0,
D3D_FEATURE_LEVEL_9_3,
D3D_FEATURE_LEVEL_9_2,
D3D_FEATURE_LEVEL_9_1
};
D3D_FEATURE_LEVEL m_featureLevel;
// Create 3D device and device context objects
D3D11CreateDevice(
nullptr,
D3D_DRIVER_TYPE_HARDWARE,
nullptr,
creationFlags,
featureLevels,
ARRAYSIZE(featureLevels),
D3D11_SDK_VERSION,
&d3dDevice11,
&m_featureLevel,
&d3dDeviceContext11); 页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
