多重采样不排他模式下工作(Multisampling doesn't work in exc

我想画的三角形就像在下面的图片时启用多重采样：

我找到了一种方法做SlimDX 另外一个问题 ，但它不以独占方式工作。

这里是我的代码：

void Form1_Load(object sender, EventArgs e)
{
    Direct3D d3d = new Direct3D();

    PresentParameters presentParams;

    presentParams.Windowed = false;
    presentParams.BackBufferFormat = Format.X8R8G8B8;
    presentParams.BackBufferWidth = 800;
    presentParams.BackBufferHeight = 600;
    presentParams.FullScreenRefreshRateInHertz = 60;
    presentParams.SwapEffect = SwapEffect.Copy;
    presentParams.BackBufferCount = 1;
    presentParams.PresentationInterval = PresentInterval.One;

    int multisampleQuality;
    Result result;
    if (d3d.CheckDeviceMultisampleType(adaptor, DeviceType.Hardware, Format.X8R8G8B8, false, MultisampleType.FourSamples, out multisampleQuality, out result))
    {
        if(multisampleQuality > 4)
        {
            presentParams.Multisample = multisampleType;
            presentParams.MultisampleQuality = 4;
        }
    }

    // Device creation
    Device device = new Device(d3d, adaptor, DeviceType.Hardware, this.Handle, CreateFlags.HardwareVertexProcessing, presentParams);
}

最后一行送花儿给人以错误crashs即使CheckDeviceMultisampleType总是返回真值与multisampleQuality没有错误和8。

它的工作原理，如果我使用窗口模式，或者如果我删除多重采样选项。

谁能告诉我有什么不对？

Answer 1:

与尝试

 presentParams.SwapEffect = SwapEffect.Discard;
