Hi,
Is it just me or does the search pattern parameter in Directory.GetFi les()
have a problem with the '?' character?
'*.*' works to find all files, but '?.*' does not work to find all files
that have only a one letter (and infinite extension size) filename. In fact,
it seems to act the same as '*.*'...
Is this by design?
Thanks in advance.

Hi Julie,
No, it's not by design, it should work. How do you use it coz that should
work: Directory.GetFi les(<path>, "*.tx?") // or "?n.*"

What version of .Net are you using? I've just tried this in .Net 2.0 (VS
2005) and it works as expected... Only files that had exactly one character
before the point (.) were listed.
Dim listOfFiles As String() = Directory.GetFi les("C:\", "?.*")
For Each filename As String In listOfFiles
Console.WriteLi ne(filename)

I have constructed a string pattern for each day (DDMMYYxx.txt). So, for
example the string pattern for today is "110707xx.t xt". The search string I
use is "110707??.t xt". However, it picked up a file called "1107071.tx t". As
you can see, that only fills one ?, not both.
I find this very weird. I might do some test scripts to see if I can
reproduce it outside my application.

Well, I ran two simulations:
string[] files = Directory.GetFi les(dir, "100707??.c nc",
SearchOption.Al lDirectories);
foreach (string s in files)
Console.WriteLi ne(s);
This returned:
\1007070.CNC
\10070701.CNC
\10070702.CNC
\10070703.CNC
\10070704.CNC
\10070705.CNC
\10070706.CNC
\10070707.CNC
\1007071.CNC
\1007072.CNC
As you can see, its not working as expected... However, changing the search
string to "100707?.cn c":
string[] files = Directory.GetFi les(dir, "100707?.cn c",
SearchOption.Al lDirectories);
This produces:
\1007070.CNC
\1007071.CNC
\1007072.CNC
This works as expected.
This is .NET 2.0 btw :-)
It is .net 2.0. My previous post to Alex shows my problem with it not
working when two ? are used together. Referring to your example, what if
your search string was "??.*", would it only list files with TWO characters
before the period?

No. It would list files with none, one or two characters before the dot (.)

I believe it is by design. Clearly you're an old hand at the DOS
prompt where ? meant a single character as opposed to .NET where it
means zero or one
-- http://bytes.thinkersroom.com
I wrote a simple test program, and I found that ?? works like *. I dont know why.
If ? means 0 or 1 character, but why did files ending with more than 2 characters show in the results, when I searched for something like "abc??.txt" in the directory? I did not work as doc.

Can you be more precise about exactly what you tried, and exactly what you
expected? Include a "dir" so we can see what the directory looked like. I
just tried an example, where ? and ?? did exactly what they were supposed
to.
Also, see if the "dir" command provides the same results with the same
glob.

I'm using Directory.GetFiles to enumerate files in a directory. The problem

Is there another way to enumerate files and subdirectories recursively which

Hi,
I'm a newbie to C#, so forgive me if this is a dumb question.
What I want to do is parse a directory of IRC logfiles and dump all the .jpg
and .gif links to a text file. If I could get a single filename, I could
load it into a richedit control and do the parsing there but
Directory.GetFiles doesn't seem to do what I want.
Any tips on how to accomplisg this task?
