Question

我正在尝试制作一个简单的SlimDX示例来测试一些性能与GDI，不幸的是我一开始就陷入困境。我在VS2010中创建了简单的控制台应用程序，并将此代码添加到程序main方法：

        // 0. STEP
        SlimDX.Direct3D10.Device device = new SlimDX.Direct3D10.Device(DriverType.Hardware, DeviceCreationFlags.BgraSupport);
        SlimDX.Direct2D.Factory factory = new SlimDX.Direct2D.Factory();

        // 1. STEP
        Texture2DDescription textureDesc = new Texture2DDescription();
        textureDesc.Width = 512;
        textureDesc.Height = 512;
        textureDesc.MipLevels = 1;
        textureDesc.ArraySize = 1;
        textureDesc.Format = SlimDX.DXGI.Format.R8G8B8A8_UNorm;
        textureDesc.SampleDescription = new SampleDescription(1, 0);
        textureDesc.Usage = ResourceUsage.Default;
        textureDesc.BindFlags = BindFlags.RenderTarget;
        textureDesc.CpuAccessFlags = CpuAccessFlags.None;
        textureDesc.OptionFlags = ResourceOptionFlags.None;
        Texture2D maskTexture = new Texture2D(device, textureDesc);

        // 2. STEP
        SlimDX.DXGI.Surface surface = maskTexture.AsSurface();

        // 3. STEPpro
        RenderTargetProperties props = new RenderTargetProperties
        {
            HorizontalDpi = 96,
            VerticalDpi = 96,
            MinimumFeatureLevel = SlimDX.Direct2D.FeatureLevel.Default,
            PixelFormat = new PixelFormat(SlimDX.DXGI.Format.Unknown, AlphaMode.Premultiplied),
            Type = RenderTargetType.Default,
            Usage = RenderTargetUsage.None
        };
        RenderTarget target = RenderTarget.FromDXGI(factory, surface, props);

使用此消息在RenderTarget.FromDXGI调用中崩溃：

Additional information: E_INVALIDARG: An invalid parameter was passed to the returning function (-2147024809)

不幸的是，我无法启用此SO问题中所述的DirectX调试输出： DirectX 10 debug output not working

......所以，这就是我所拥有的一切。

但是，我在家里（win8.1，vs2013）和工作（win7，vs2010sp1）尝试了这一点，在家里，当我使用2013年的Graphics Diagnostics调试应用程序时，它可以工作当我开始定期调试或尝试手动启动exe时，它不起作用。在工作中它根本不起作用。

来自代码的任何想法？我在这里绝望。：（

我刚刚注意到你对我的另一个答案的评论。这是我使用的创建功能：

    public static Texture2D CreateRenderTexture(this RenderHelper helper, int width, int height)
    {
        Texture2DDescription description = new Texture2DDescription
        {
            ArraySize = 1,
            BindFlags = BindFlags.RenderTarget | BindFlags.ShaderResource,
            CpuAccessFlags = CpuAccessFlags.None,
            Format = SlimDX.DXGI.Format.B8G8R8A8_UNorm,
            Width = width,
            Height = height,
            MipLevels = 1,
            OptionFlags = ResourceOptionFlags.None,
            SampleDescription = new SlimDX.DXGI.SampleDescription(1, 0),
            Usage = ResourceUsage.Default,
        };

        return new Texture2D(helper.Device, description);
    }

E_INVALIDARG：将无效参数传递给返回函数
