我们如何在Windows Phone 8.1应用中检测Windows 10？

Question

my app (developed in Windows Phone 8.1 RT environment) uses OpenFilePicker which allows me to choose image and capture an image, it works great however when I deployed this app on a Windows 10 device, this function just allowed me to pick an image from the library. I thought about a solution, writing a small code block which can help me to detect the version of the OS like this

#if WINDOWS_PHONE_APP
//codes
#endif

But I don't know exactly what I need to do, so please help me!

Read this link:

it purpose a simple solution to check is OS has Windows 10 features with reflection:

var analyticsInfoType = Type.GetType("Windows.System.Profile.AnalyticsInfo, Windows, ContentType=WindowsRuntime"); 
var versionInfoType = Type.GetType("Windows.System.Profile.AnalyticsVersionInfo, Windows, ContentType=WindowsRuntime"); 

if (analyticsInfoType == null || versionInfoType == null) 
{ 
 // That's not Windows 10
}
