There are some classes (of the .NET framework 3.5) that contain some methods that are supported in .NET Compact Framework, and some methods that are not supported. There are also some classes that does not exists for the .NET Compact Framework.
For example for the System.IO.File class, the File.Create function is supported by .NET Compact Framework, but the File.Encrypt function is not.
Another example: the System.IO.File class is supported by .NET Compact Framework, but the System.Diagnostic.StackTrace is not.
I need to tell to the compiler something like this:
#ifdef COMPACT_FRAMEWORK // I'm compiling this from a smart device project
MyEncryptMethod("filename");
#else // I'm compiling this from a desktop project
File.Encrypt("filename");
#endif
How can I do?
(The specific version is Windows Mobile 6.1 Professional).
Just to add, since you are showing windows-mobile and windows-mobile-6, you should change your #define constraint to PocketPC instead of COMPACT_FRAMEWORK.
#ifdef PocketPC // PocketPC is what the WM SDK uses
MyEncryptMethod("filename");
#else // I'm compiling this from a desktop project
File.Encrypt("filename");
#endif
Update:
Nick: What yms said. :) When building a project using one of the Smart Device projects, Visual Studio automatically add the conditional compilation symbol PocketPC to the project.
From within VS2008's Main Menu, click Project and select your project's Properties at the bottom.
On your project's Properties page, go to the Build tab, and there you will see where PocketPC is already defined for you.
