How to know the current OS / platform of the executing code (Android / iOS)

Question

Using Xamarin.Android and Xamarin.iOS, I need to now the current OS in a shared code section. Be it an enum, an int or a string, it doesn\'t matter.

I tried this:

Answer 1

I'm using DeviceInfo plugin. It supports Android, iOs, Windows Phone Silverlight, Windows Phone RT, Windows Store RT, Windows 10 UWP and it works perfectly.

It can be used in PCL like this (you must add the plugin to the platform projects and to PCL):

var platform = CrossDeviceInfo.Current.Platform;
    switch(platform){
        case Platform.iOS:
            // iOS
            break;
        case Platform.Android:
            // Android
            break; 
    }

This kind of code isn't a good practice in PCL, its better to use Dependency Injection (this plugin use that) to customize platform specific behaviour.
