c# - 检查kinect是否连接

Question

我正在创建一个 WPF/C# 应用程序，它使用 kinect 来移动对象，但它也可以使用鼠标运行。目前我注释掉了 kinect 代码，因为它可以使用鼠标工作。我需要识别 kinect 是否已连接的方法，因此我不必注释掉代码以在未连接时使用鼠标(不会像当前那样抛出异常)并在连接时使用 kinect。
我该怎么做？
信息:我正在使用官方的 Microsoft Kinect SDK(大约一周前下载)

无法添加引用和使用 Microsoft.Kinect，因为它会与其中一些产生冲突

Device dvc = new Device();
            if (dvc.Count.Equals(0))
                MessageBox.Show("apoellin");

我尝试了上面的代码，如果我在 Kinect 未连接的情况下使用任何 Kinect 代码，应用程序会崩溃并出现相同的错误

这是《Beginning Kinect Programming with the Microsoft SDK》一书中的代码，它很好地处理了这个问题

// (in your page/window constructor):

this.KinectDevice = KinectSensor.KinectSensors
.FirstOrDefault(x => x.Status == KinectStatus.Connected);

// (and create a property like this:)

public KinectSensor KinectDevice
{
get { return this._KinectDevice; }
set
{
if (this._KinectDevice != value)
{
//Uninitialize
if (this._KinectDevice != null)
{
this._KinectDevice.Stop();
this._KinectDevice.SkeletonFrameReady -= KinectDevice_SkeletonFrameReady;
this._KinectDevice.SkeletonStream.Disable();
this._FrameSkeletons = null;
}

this._KinectDevice = value;

//Initialize
if (this._KinectDevice != null)
{
if (this._KinectDevice.Status == KinectStatus.Connected)
{
this._KinectDevice.SkeletonStream.Enable();
this._FrameSkeletons = new
Skeleton[this._KinectDevice.SkeletonStream.FrameSkeletonArrayLength];
this.KinectDevice.SkeletonFrameReady +=
KinectDevice_SkeletonFrameReady;
ColorImageStream colorStream = this._KinectDevice.ColorStream;
colorStream.Enable();
this._ColorImageBitmap = new WriteableBitmap(colorStream.FrameWidth,
colorStream.FrameHeight, 96, 96, PixelFormats.Bgr32, null);
this._ColorImageBitmapRect = new Int32Rect(0, 0, colorStream.FrameWidth,
colorStream.FrameHeight);
this._ColorImageStride = colorStream.FrameWidth * colorStream.FrameBytesPerPixel;
ColorImageElement.Source = this._ColorImageBitmap;
this._KinectDevice.ColorFrameReady += Kinect_ColorFrameReady;

this.ColorImageElement.Dispatcher.BeginInvoke(new Action(() =>
{
this._ColorImageBitmap = new WriteableBitmap(colorStream.FrameWidth,
colorStream.FrameHeight,
96, 96, PixelFormats.Bgr32,
null);
this._ColorImageBitmapRect = new Int32Rect(0, 0, colorStream.FrameWidth,
colorStream.FrameHeight);
this._ColorImageStride = colorStream.FrameWidth *
colorStream.FrameBytesPerPixel;
this._ColorImagePixelData = new byte[colorStream.FramePixelDataLength];

this.ColorImageElement.Source = this._ColorImageBitmap;
}));
this._KinectDevice.Start();
}
}
}
}
}
