Summary: FileStream constructor throws incorrect exception
Original Submission: According to the MSDN docs and testing with Rotor, when
the FileStream constructor that takes a filename and mode is used, and the file
is not found, a FileNotFoundException should be thrown. Pnet throws the more
generic IOException ("operation not permitted"). IOException does not include
information about the file that caused the error, so catching IOException does
not permit a very descriptive error message.
The test case I'm attaching aborts with this error on Rotor:
Unhandled Exception: System.IO.FileNotFoundException: Could not find file
"/home/marcus/alpha/test-cases/DoesNotExist".
File name: "/home/marcus/alpha/test-cases/DoesNotExist"
at System.IO.__Error.WinIOError(Int32 errorCode, String str)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access,
FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath, Boolean
bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode)
at Testing.Main()

FileStream is not the culprit here from what I can tell. It handles the ENOENT
errno and deals with the directory and file not found exceptions. I've only
been able to trace back as far as pnet/support/file.c:ILSysIOOpenFile, both
functions, the first seams to only set EACCES, and the second ENOENT (perhaps
someone can explain to me why there are two..)
