But there is no option to find the device orientation in the Windows Phone 8 . Could you please anyone help me on this ?

推荐答案

您可以使用加速度传感器的读数，然后采取ATAN2如下：<？ / p>

You can use the acceleration sensor readings and then take the atan2 as follows:

angle = Math.Atan2(-x,y) * 180.0 / Math.PI;

，其中角是设备的方向relativ到默认的纵向。

where "angle" is the device orientation relativ to the default portrait orientation.
