Created an attachment (id=342582)
 --> (http://bugzilla.novell.com/attachment.cgi?id=342582)
Source code and test data to reproduce the bug.

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.7)
Gecko/20100106 Ubuntu/9.10 (karmic) Firefox/3.5.7

The System.IO.Directory.GetFiles(string directory, string searchPattern) method
fails to execute when searchPattern contains an existing directory (ad es:
'directory/*'). 

On ubuntu systems (9.10) upon a call of the following type:

string items[] = Directory.GetFiles(".", "test/*");

the reported error is the following:

Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a
part of the path "./test"
  at System.IO.Directory.GetFileSystemEntries (System.String path,
System.String searchPattern, FileAttributes mask, FileAttributes attrs)
[0x00000] 
  at System.IO.Directory.GetFiles (System.String path, System.String
searchPattern) [0x00000] 
  at FilesAndDirs.Program.Main (System.String[] args) [0x00000] 

On Windows systems the same lines of code produces the expected output, which
is the list of file names in the test directory.

The specification provided by the MSDN documentation for the method, which is
available at: http://msdn.microsoft.com/en-us/library/wz42302f.aspx, explicitly
states that searchPattern should not contain invalid path chars, but the .NET
framework implementation tested on Windows XP systems (.NET 2.0) nicely handles
this input.





Reproducible: Always

Steps to Reproduce:
1. Untar the attachment and move to the bin/Debug directory.
2. Create a local directory named 'test' (mkdir test)
3. Save four files into the 'test' directory.
   ls -al > test/file1.txt
   ls -sl > test/file2.txt
   ls -as > test/file3.txt
   ls -als > test/file4.txt

3. Run the test application with the following arguments: . test/\*
   mono FilesAndDirs.exe . test/\*

Actual Results:  
Testing Directory.GetFiles(.,test/file1.txt)...
Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a
part of the path "./test"
  at System.IO.Directory.GetFileSystemEntries (System.String path,
System.String searchPattern, FileAttributes mask, FileAttributes attrs)
[0x00000] 
  at System.IO.Directory.GetFiles (System.String path, System.String
searchPattern) [0x00000] 
  at FilesAndDirs.Program.Main (System.String[] args) [0x00000] 

Expected Results:  
Testing Directory.GetFiles(.,test/*)...[OK - 4 Found]
Testing Directory.GetDirectories(.,test/*)...[OK - 0 Found]
