Xamarin是否有#if或#ifdef来确定平台？

Question

例如,#ifdef iOS,#ifdef android等.如果有#if,那就更好了.

Answer 1

iOS版:

#if __MOBILE__
    Console.WriteLine ("__MOBILE__ is defined");
#endif 

#if __IOS__
    Console.WriteLine ("__IOS__ is defined");
#endif

#if __MOBILE__
    Console.WriteLine ("__MOBILE__ is defined");
#endif 

#if __ANDROID__
    Console.WriteLine ("__ANDROID__ is defined");
#endif
