获取Windows 8.1项目中的屏幕亮度级别

Question

是否可以使用C＃在Windows 8.1项目或通用Windows应用程序中获取设备（显示器/平板电脑/手机）的当前亮度级别？

我从System.Management dll获得了一个查询代码。

static int GetBrightness()
        {
            System.Management.ManagementScope s = new System.Management.ManagementScope("root\\WMI");

            System.Management.SelectQuery q = new System.Management.SelectQuery("WmiMonitorBrightness");

            System.Management.ManagementObjectSearcher mos = new System.Management.ManagementObjectSearcher(s, q);

            System.Management.ManagementObjectCollection moc = mos.Get();

            byte curBrightness = 0;
            foreach (System.Management.ManagementObject o in moc)
            {
                curBrightness = (byte)o.GetPropertyValue("CurrentBrightness");
                break;
            }

            moc.Dispose();
            mos.Dispose();

            return (int)curBrightness;
        }

但那不适用于应用项目。
