If you're on Android 6.0+ you will need to perform a runtime check for permissions. This can be done like so:

if ((CheckSelfPermission(Permission.ReadExternalStorage) == (int)Permission.Granted) && 
    (CheckSelfPermission(Permission.WriteExternalStorage) == (int)Permission.Granted))

More information on this can be found in the android documentation here.
