PCL libraries and similar File.Exists functions

Question

Im new in the new version of Mono 4.2 and they implement the new PCL libraries, My question is there is a similar function like File.Exists that works on PCL, and if I mix this libraries with the full ones, there will be a problem with the compatibility of this dll in iOs. Thank you.

Answer 1

You can use my PCL Storage library for cross-platform file IO access. It doesn't have a separate method to check for existence of a file, but you can call IFolder.GetFileAsync and check if it throws a FileNotFoundException.

Answer 2

File System is handled differently on each operation system, so you are going to need to write platform specific code, or use pre-made cross-platform framework's plug-ins.

I suggest you to take a look at MVVMCross framework, for mobile development in general, and specifically at the File Plugin of MVVMCross.
