检查kinect是否已连接

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.目前我使用鼠标注释掉它的kinect代码.我需要知道kinect是否已连接,所以我不需要注释代码,因为它不能使用鼠标(没有像现在这样抛出异常),并且当它发生时使用kinect.我该怎么办？info:我正在使用官方的Microsoft Kinect SDK(大约一周前下载)

编辑 - 我正在使用这些

using System;
using System.ComponentModel;
using System.Threading;
using System.Windows;
using System.Windows.Media;
using System.Windows.Input;
using System.Windows.Media.Media3D;
using System.Windows.Media.Animation;

using System.Windows.Data;
using Microsoft.Research.Kinect.Samples.CursorControl;
using Coding4Fun.Kinect.Wpf;
using Coding4Fun;
using System.Speech.Synthesis;

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

编辑 -

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

我尝试了上面的代码和应用程​​序崩溃同样的错误它崩溃如果我使用任何Kinect代码与Kinect没有连接

这是"使用Microsoft SDK开始使用Kinect编程"一书中的代码,它可以很好地处理这个问题

// (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();
}
}
}
}
}
