I think this is misleading. With Mono 2.0.1, I get
** (/tmp/a.exe:30553): WARNING **: FindNextFile: Bad encoding for
'/home/martin/work/3k/t/\xff'
Consider using MONO_EXTERNAL_ENCODINGS
when running the program
using System.IO;
class X{
public static void Main(string[] args){
DirectoryInfo di = new DirectoryInfo(".");
foreach(FileInfo fi in di.GetFiles())
System.Console.WriteLine("Next:"+fi.Name);
}
}
On the other hand, when I write
using Mono.Unix;
class X{
public static void Main(string[] args){
UnixDirectoryInfo di = new UnixDirectoryInfo(".");
foreach(UnixFileSystemInfo fi in di.GetFileSystemEntries())
System.Console.WriteLine("Next:"+fi.Name);
}
}
I get indeed all files listed (and can also find out the other
stat results). Of course, the resulting application will be
mono-specific (it links with Mono.Posix), and not work on Microsoft
.NET anymore. IOW, IronPython likely won't use this API.
Python, of course, already has the equivalent of that: os.listdir,
with a byte parameter, will give you access to all files. If
you wanted to closely emulate the Mono API, you could set
the file system encoding to the mono-lookalike codec.
