我正在开发 Windows 8.1 商店应用程序。我想获取当前设备的操作系统类型并将其同步到服务器。
例如，我想知道我当前的操作系统是 Windows 10、Windows 8 还是 Windows 8.1。我找不到关于如何做到这一点的地方，目前我正在使用：
MachineInfo = new EasClientDeviceInformation();
MachineInfo.OperatingSystem;
但是，这只会给我“WINDOWS”。
我还需要其他信息，例如：
设备屏幕尺寸
提前致谢
我在 GitHub 上找到了这个：

ALPHA64 = 7,
MSIL = 8,
AMD64 = 9,

}
这是我使用它的方式：
public async Task<string> GetOSVersion()
{
var version = await WindowsStoreSystemInfo.GetWindowsVersionAsync();
string result = String.Format("{0} {1}", MachineInfo.OperatingSystem, version);
return result;
}
而且效果很好:)
