我正在构建使用相机的Windows Phone应用程序。我的代码:Windows Phone - 访问相机需要ISV相机功能
private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
if ((PhotoCamera.IsCameraTypeSupported(CameraType.Primary) == true) ||
(PhotoCamera.IsCameraTypeSupported(CameraType.FrontFacing) == true)) {
// Initialize the default camera.
_photoCamera = new Microsoft.Devices.PhotoCamera();
//Event is fired when the PhotoCamera object has been initialized
_photoCamera.Initialized += new EventHandler<Microsoft.Devices.CameraOperationCompletedEventArgs>(OnPhotoCameraInitialized);
//Set the VideoBrush source to the camera
viewfinderBrush.SetSource(_photoCamera);
}
else {
// The camera is not supported on the device.
this.Dispatcher.BeginInvoke(delegate() {
// Write message.
txtDebug.Text = "A Camera is not available on this device.";
});
}
}
private void OnPhotoCameraInitialized(object sender, CameraOperationCompletedEventArgs e) {
int width = Convert.ToInt32(_photoCamera.PreviewResolution.Width);
int height = Convert.ToInt32(_photoCamera.PreviewResolution.Height);
}
而且我不断收到异常:“访问摄像头需要ISV相机能力”
我有一个Lumia 900
,我知道它运行相机APIs
(样品表格MS工作正常)。但是当我把这段代码放到我的应用程序中时,我得到了这个异常。有谁知道可能会发生什么?我是一个好的C#
'呃,但Windows Phone对我来说是相当新的。
非常感谢! 布雷特
