Silverlight调用摄像头

概述 CaptureSource source = new CaptureSource();         private void UserControl_Loaded_1(object sender, RoutedEventArgs e)         {             VideoCaptureDevice vcd;             //话筒就换成这个类 AudioCaptu

 CaptureSource source = new CaptureSource();
        private voID UserControl_Loaded_1(object sender,RoutedEventArgs e)
        {
            VIDeoCaptureDevice vcd;
            //话筒就换成这个类 AudioCaptureDevice 
            vcd = CaptureDeviceConfiguration.GetDefaultVIDeoCaptureDevice();

            source.VIDeoCaptureDevice = vcd;

            VIDeoBrush vIDeo = new VIDeoBrush();
            vIDeo.SetSource(source);
            rectangle1.Fill = vIDeo;

            //截图的回调              source.CaptureImageCompleted += new EventHandler<CaptureImageCompletedEventArgs>(source_CaptureImageCompleted);         }                //截图调用 source.CaptureImageAsync();          voID source_CaptureImageCompleted(object sender,CaptureImageCompletedEventArgs e)         {             WriteableBitmap img = e.Result;         }                 //此处开始启动         private voID button_Click_1(object sender,RoutedEventArgs e)         {             if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess())             {                 //启动摄像头 /麦克风以及其他 *** 作                  source.Start();             }         }
